Title:Improved Mixed-Mode Simulation Tools for Radiation Hardening of Nanoscale Semiconductor Integrated Circuits
Abstract:Strategic DoD satellite and missile systems (Space Based Radar, Space Tracking Surveillance Systems) operate in harsh radiation environments, and will be increasingly based on novel sub-100-nm semiconductor technologies and highly complex circuits. In order to ensure interruption-free operation, accurate prediction of the radiation response of these technologies and circuits is critical. To address this challenge, CFDRC, in collaboration with ISDE/Vanderbilt University, Mentor Graphics and Honeywell, proposes to develop an innovative mixed-mode simulation tool, which will feature: (a) Efficient coupling between CFDRC's NanoTCAD 3D device simulator and Berkeley SPICE circuit solver. This coupled tool will permit radiation-effects analysis at device-physics and full-scale circuit levels. (b) Improved quantum-physics models to accurately predict behavior of nanoscale technologies (90 nm, 65 nm). (c) Nanoscale radiation-effects models, such as Geant 4 particle ionization model, which are critical for deep-submicron technologies. In Phase I, the mixed-mode tool will be demonstrated for Single Event Effects in digital circuits. Additionally, alternative coupling mechanisms of NanoTCAD with ELDO circuit solver (Mentor Graphics) and with high-level behavioral simulator ModLyng (Lynguent) will be explored. In Phase II, analog circuitry and other radiation effects (Total Dose, Dose Rate) will be addressed, and the NanoTCAD interfaces with ELDO and ModLyng will be implemented.

Title:HIGH EFFICIENCY COMPACT MODELING OF RADIATION EFFECTS
Abstract:The objective of this research is prove the feasibility of automatically migrating radiation effects predicted in TCAD level tools to compact modeling tools. This transition will enable compact models that possess radiation effects to be quickly generated, which can then be used in circuit design activity. This "model-in-a-day" approach is a substantial improvement over the current ad hoc approaches. Lynguent will develop and demonstrate model-based design tools for systematically supporting the rapid deployment of radiation-enhanced compact models including the vital step of model validation. The intent is for these modeling and verification tools to be "added-on" as third party tools to existing commercial simulators, TCAD tools, and design environments promoting their rapid adoption and widespread use. The desire is to provide a standardized approach for modeling and collaborative design independent of the underlying design environment. Phase I will focus on radiation effects in 65 nm technology. We will investigate the prevalent radiation effects at this process node, modify a TCAD model to predict the effects on the device, and then demonstrate how these effects can be transitioned to compact models. Phase II will consist of expanding this work and fully automating this capability in a general sense using commercial applications.

Title:Radiation Effects in Semiconductor Electronics
Abstract:Radiation-effects modeling community has experienced a growing need for mixed-mode simulation capabilities when analyzing advanced semiconductor technologies. Space Micro Inc. and Silvaco International have worked closely to enable and test radiation-effects modeling capabilities in Silvaco's TCAD simulation framework in the past. This simulation framework also includes 2D- and 3D-mixed mode simulators targeted at commercial technologies but lacks the physics and computational stability/efficiency needed to address radiation-hardening methodologies for DoD strategic and commercial space applications. In addressing the current solicitation, we propose to implement physical radiation-effects models in Silvaco's MixedMode-3D software and, during Phase I, demonstrate the ability to address a set of key radiation hardening issues in digital CMOS/SOI technologies that cannot be analyzed using existing software. This innovation represents a cost-effective and rapid development method for radiation-effects-aware 3D mixed-mode modeling tools and will provide a path for rapid deployment of traditional radiation-hardening techniques into the design flow of advanced commercial as well as DoD-dedicated foundries.

Title:Reactive-Fiber-Reinforced Composites as Structural Materials
Abstract:We propose to develop reactive composite materials with sufficient strength and stiffness to serve as structural components for penetrating weapons and other munitions. The composites will consist of two materials that react with each other, in either oxidation-reduction (such as in a thermite) or bimetallic reactions. One component will be in the form of fiber, wire, or wire-mesh, within a bonding matrix of the other component or a third material, such as epoxy or other polymer. The result will be a fiber-reinforced composite material with substantial strength and stiffness properties that can be tailored to specific applications, while providing significant thermal energy release on impact. This greater energy on impact will provide increased weapons effectiveness, including in defeating hard and deeply buried targets. Various material systems and conventional composites fabrication techniques will be investigated.

Title:Novel Reactive Structural Materials
Abstract:Materials and Manufacturing Systems, Inc. (MATSYS) proposes to develop novel reactive structural materials for the enhancement of munitions lethality. This effort will combine our unique expertise in instrumented-Hot Isostatic Pressing (HIP) with new approaches in intermetallic design to develop a new generation of cost-efficient, high strength and reactive composites. The proposed material system will have a blend of three elemental powders, consisting of two highly reactive materials interspersed with a reactive "binder" material. The powder blend will be consolidated to full density to maximize the mechanical properties, and below the reaction temperature to preserve the energy for release upon target impact. The existence of three different powders will allow for tailoring of mechanical and reactive properties of the composite by varying the volume fraction of each element, and adjusting the particle size. MATSYS high temperature sensor for real-time monitoring of HIP combined with our consolidation models will enable rapid characterization of densification of powder mixtures, identification of mixtures of interest, and insertion of this new class of materials. MATSYS will demonstrate the versatility of the approach by fabricating high strength and reactive composites that will enhance the munitions lethality by releasing a large amount of exothermal heat upon target impact.

Title:Discontinuous Graphite Fiber Reinforced Al 520 Matrix Composite for Structural Reactive Material
Abstract:Discontinuous graphite fiber reinforced aluminum magnesium matrix composite with microscopically dispersed add-on oxidizer coating is proposed for the application of enhanced lethality munitions. The composite with the coating is light-weight and reactive, which will generate high reaction temperature and a large amount of reaction heat. The composite also has sufficient mechanical strength for many structural applications. And more importantly, the dynamic behaviors of the composite are inline with the requirements and applications of reactive materials. Upon impact, the composite is fractured into small fragments due to the presence of graphite fibers. These small fragments can react easily and quickly. During Phase I, MMCC will team up with University of California, San Diego to study the constitutive behavior of this composite.

Title:Novel Energetic Materials
Abstract:Reactive warheads increase lethality by igniting propellants/fuels in targets, by melting and destroying electronic components, by providing substantial blast overpressure effects inside of the target after impact, and by providing heat energy to destroy potential biological and chemical payloads. Currently, the range of reactive material options is largely limited to Al-polymer composites, thermites, and intermetallics. In the Proposed Phase i SBIR program, Powdermet will investigate a series of metal/salt nanocompostes that can be tailored to provide a wide range of thermal profiles and energies. By controlling structure at the nanoscale, ignition, burn rate, and safety issues can be addressed and tailored.

Title:Reactive Coating Materials as Lethality Enhancers
Abstract:In this SBIR Phase I/II effort, Structured Materials Industries, Inc. (SMI) will develop and demonstrate a thin film coating technology that can serve as both lethality enhancers and as functional coatings for munitions. The goal of this project is twofold: 1) we will fabricate and characterize reactive thin films that rapidly release large quantities of thermal energy and 2) we will develop a technology to manufacture lethality enhancing coatings based on such thin films. Reactive thin films are comprised of multilayer compositions of nano-energetic materials. Total film thickness typically is on the order of 1 - 10 um, with individual layer thickness ranging from 10 nm to 100 nm. Multilayer films are typically formed by alternating layers of a metal such as Al a with metal oxides such as CuO or Fe2O3. The potential of these materials to release large quantities of thermal energy is well established. The feasibility of energetic materials in thin film form has previously been demonstrated in an Al/CuO system. In this SBIR effort, SMI proposes to further develop reactive thin film technology to allow for larger quantities of thermal energies to be released upon ignition so as to make implementation in future weapons possible.

Title:Title: Chemical/Biological Agent Standoff Detection
Abstract:Spectral Sciences, Inc. proposes an innovative standoff detection system to enable military personal to detect the presence of chemicals agents and other hazardous materials from large (multiple kilometer) distances. The proposed system combines a revolutionary adaptive spectrometer concept with advanced signal processing algorithms to provide detection and quantification based on the thermal infrared signature of the agent. The adaptive spectrometer is a compact and inherently stable optomechanical system, with no moving parts, that exceeds the performance of current FTIR systems. The spectrometer's spectral range, resolution, and other operating characteristics can be set in software, on-the-fly, providing the flexibility to adapt to a variety of measurement scenarios. The spectrometer can be programmed to perform specific detection algorithms directly in hardware, thereby reducing processing time and increasing selectivity for detecting weak spectral signatures against complex spectral backgrounds. Phase I will demonstrate the feasibility of the approach and develop a conceptual design for a Phase II prototype standoff chemical monitor.

Title:High Resolution Radiation Detection with Sub-Micron Light Trapping Structures
Abstract:Intelligent Optical Systems proposes to develop an innovative optical fiber radiation detector whose light trapping efficiency will be greater than an order of magnitude higher than current radiation detectors. Photonic crystal-like optical fibers with novel liquid scintillating cores will be evaluated and tested. These novel photonic crystal light emitting fibers, or PCLEFs, are expected to have high light efficiency due to the quantum-confinement effect, and will increase sensitivity in numerous radiation sensing applications. The proposed technological advance will improve light efficiency in radiation detection, and thereby the sensitivity of radiation imaging devices, primarily in homeland defense, security, and medical (radiation therapy) applications. In Phase I, we will demonstrate an increase of the spontaneous emission response to radiation, at room temperature, that will suffice for energy resolution of 1% or better. The proposed technology will have societal benefits, in that it will help to obtain earlier and timely responses to radiation in homeland security applications, and for medical diagnostics. The understanding gained during this PCLEF development program will be applicable to a wide range of light emitter and detector designs. This technology also has potential implications for energy-savings in reducing the cost of luminous intensity per watt of electrical power consumption.

Title:Field-Deployable, High Resolution, High Pressure Xenon Gamma Ray Spectrometer
Abstract:There is a need for the detection and characterization of specific radioisotopes in the interest of homeland security, treaty verification, and customs. Current high resolution spectrometers require operating temperatures at liquid nitrogen levels and are highly expensive to maintain. Other spectrometers which operate at room temperatures do not afford the resolution required to distinguish and identify many radioisotopes of interest. Further, many devices are subject to acoustic interferences which significantly degrade their performance in field operations. Thus, there is a need for a rugged, self-contained, high resolution gamma ray spectrometer which is both portable and field-deployable. We propose using high pressure Xenon (HPXe) gas as a spectroscopic medium for building a portable, room temperature, high resolution gamma ray spectrometer. An innovative method of incorporating a reflective coating inside the detector will be developed so VUV scintillation light emission from the Xenon gas can be used to correct for geometric signal dispersion in the detector, producing a spectroscopic resolution approaching 0.45% at 662 keV in a device with high immunity to acoustic effects. At the end of the project, a full-scale, rugged, portable, self-contained, and high resolution HPXe spectrometer will be available for use in field operations.

Title:High Resolution, Room Temperature Semiconductor Detectors
Abstract:Proliferation of the weapons of mass destruction such as nuclear weapons is a serious threat in the world today. Prevention of the spread of nuclear weapons has reached a state of heightened urgency in recent years, especially since the events on September 11, 2001 and its aftermath. Gamma ray spectrometers are an important tool in checking the proliferation of the nuclear weapons. Important requirements for the gamma ray spectrometers used in this application include good energy resolution, high detection efficiency, compact size, light weight, easy portability, and low power requirements. None of the available gamma-ray sensors satisfy all these requirements. The goal of the proposed effort is to investigate a high efficiency semiconductor detector that promises high energy resolution at room temperature.

The dosimeter will have high sensitivity and multiple operational functions. A custom integrated circuit will be developed to achieve the proposed specifications. It will have long life and automatic data recording capabilities and will be developed to have low manufacturing cost for wide deployment in large quantities.

Title:Low-cost Individual Digital Dosimeters using Solid State Photomultipliers
Abstract:U.S. forces working in low-level radiation environments have unsatisfactory choices for monitoring radiation exposure. The currently available A/UDR-13 pocket dosimeter is able to meet sensitivity requirements, but is cost prohibitive at ~$400 per unit, and it fails in the high temperature environments faced our military. Careful monitoring and accurate reporting of the exposed dose will reduce threats to the defense of our soldiers and our nation. The solution to these problems is an integrated detector-on-a-chip using a solid-state photomultiplier (SSPM) fabricated with CMOS (complementary metal-oxide-semiconductor) technology. An array of CMOS avalanche photodiode (APD) pixels comprises the SSPM, which is monolithically integrated to the readout and USB data transfer electronics. Coupling this detector-on-a-chip to a scintillation crystal provides an integrated platform for a low-cost, rugged, digital dosimeter. The Phase I work will demonstrate the feasibility of utilizing a SSPM, coupled to a scintillation crystal, to provide a low-cost, rugged, temperature tolerant individual digital dosimeter by measuring the sensitivity and energy resolution of a prototype, at two temperature extremes, and performing an analysis of the production costs.

Title:Active Interrogation for Nuclear Materials Detection
Abstract:Physitron proposes the development of a Thermal Neutron Beam Concentrator for use in detecting strategic nuclear material (SNM) such as U, Pu, Th, etc. A compact neutron generator developed by Lawrence Berkeley National Lab will provide 2.4 MeV neutrons that will be moderated, concentrated into a high flux beam, and propagated in air across distances up to three meters. Any SNM in the beam's path will produce a neutron-gamma conversion process that can be detected and analyzed by a gamma spectrometer leading to the identification of the SNM. Phase I will be used to design, analyze and predict the properties of a TNBC. This unit will consist of three major subassemblies: the neutron generator, a moderator to lower the neutron's average energy, and a concentrating optic to form a high flux beam of thermal neutrons. Scientists from LBNL have been researching high fluence neutron generators while Physitron has developed both photon and neutron optics for concentrating, collimating and/or bending them for many different applications. The collaboration between LBNL and Physitron will allow these two areas to be combined and provide a significant increase in the available neutron fluence for detecting SNM.

Title:Non-Energetic Payload Technologies
Abstract:Conventional weapons rely on blast and fragmentation as the primary defeat mechanism, whereas non-energetic payloads rely on other means to defeat the target. Non-energetic weapons may defeat targets by the dispersion of aerosols (solid or liquid) or gases to interact with critical target elements. The objective is to cause some combination of denial, disruption, degradation, or destruction without the transfer of excessive energy to the target and thereby minimizing collateral effects. The target set includes hardened targets that vary in size, complexity, and may be above or below ground. Here we propose an innovative modification of reactive materials to improve performance and safety. We propose to develop sample compositions and characterize their key properties just enough to enable their comparison with the virgin composition. Thus, we can assess concept feasibility in Phase I. A detailed examination can then be conducted in Phase II.

Title:Non-Energetic Payload Technologies
Abstract:To address the needs of the Defense Threat Reduction Agency (DTRA), GSI will perform in three areas during the course of this effort. 1) GSI will evaluate a new formulation, capable of self-propagating reaction with the production of an electrically conductive aerosol, for the purpose of Intrusive Electronic Equipment Defeat. This material will be evaluated against electronic equipment (PC's) and also against dispersed Biological Agent simulants (Bt and Bg). GSI has the capability to evaluate performance against electronic targets and biological agent simulants in-house. 2) GSI will fabricate a non-hydrocarbon Black Smoke Generator (BSG) using an existing GSI formulation. The BSG will be demonstrated for DTRA at the GSI site. GSI will provide an additional device to DTRA for further demonstrations at an off-site location. 3) GSI will fabricate and demonstrate a High Temperature FireStart Device (HTFSD). GSI will show the effectiveness of this device in raising room temperature to the flashover point. GSI will utilize existing formulations for this task. General Sciences, Incorporated (GSI) has developed a formulation, which produces an electrically shunting, corrosive material from a thermally activated source, for use within a tunnel environment. This material is generated from a thermal decomposition of a material, travels as a fine mist in existing air currents as well as due to the slight overpressure developed during the reaction and then settles out on available surfaces. This residue is electrically conductive and corrosive, causing immediate failures of computers and other sensitive electronics, as well as delayed failure of "harder" targets, such as generators. GSI has also developed concepts involving enhanced obscurants and high temperature thermal sources, which can be, used as thermal accelerants; these concepts are better suited to smaller volumes or stealth applications. The proposed effort will build on progress to date to better address threats of interest to DTRA.

Title:Waterborne Transport Modeling Capability
Abstract:The Defense Threat Reduction Agency has expressed the need for waterborne transport and dispersion capability to compliment its existing models for Chemical, Biological, Radiological and Nuclear (CBRN) releases. DTRA's current capability is limited to the atmospheric transport of CBRN agents using the HPAC system. The objective of this proposed Phase I study is to couple Applied Science Associates (ASA) waterborne chemical transport and dispersion model, in a two-dimensional mode, with the HPAC system as a feasibility assessment for future complete integration of the modeling systems. An integration effort is proposed. Algorithm development is not needed due to ASA's existing operational waterborne chemical dispersion modeling capability. In addition, DTRA has advised that the source code for the HPAC system will not be available during Phase I of the project; hence the integration effort will focus on data access and sharing between ASA's CHEMMAP system and DTRA's HPAC system. Maintaining individual systems at this stage is also necessary since HPAC does not provide access to oceanographic information such as currents, temperature and salinity which are of critical importance to the transport of chemicals in marine and freshwater environments.

Title:Waterborne Transport Modeling Capability
Abstract:We propose to develop a computational model and associated software library to calculate the transport and dispersion (T&D) of hazardous materials into and through the water. The model is developed for incorporation into HPAC and will compliment its existing atmospheric T&D model for CBRN (including toxic industrial substances) releases. We will investigate existing T&D models including those developed by Arete for other DoD programs and develop prototype algorithms for (initially) a 2-D waterborne transport module. The computational algorithm developed will emphasize the balance between accuracy and speed so that it will be useful within the HPAC framework. The model will incorporate various databases where available and be sufficiently general to describe waterborne transport in various parts of the world having diverse geographic (e.g. rivers, ports and coastal regions) and environmental (tidal, seasonal, and weather) conditions. The model and software library developed in Phase I will serve as foundation to be enhanced in phase II to a fully 3-D T&D model with coupled air-sea interaction capability.

Title:Advanced Radiation Detector
Abstract:To address the DTRA need to prevent terrorist nuclear attacks by early identification of radiological dispersal devices (RDD) and improvised nuclear devices (IND), Physical Optics Corporation (POC) proposes to develop a new low-cost large area Advanced Radiation Detector (ARAD), highly sensitive to gamma and X-rays with energies up to 1 MeV. The ARAD is based on NaI(Tl) scintillator and large arrays of high-aspect-ratio microchannels in silicon wafers. The ARAD will have high sensitivity, high resolution, high SNR, and CCD readout. The ARAD design will be compatible with existing semiconductor production process, significantly reducing the cost of NaI(Tl) detectors to $5 per 2 in. square detector, unlike current detectors that cost $350. In Phase I we will design, fabricate, and test an ARAD prototype for hard X-ray energies up to 90 keV. In Phase II POC will demonstrate a working ARAD engineering prototype operating in the range up to 1 MeV with the CCD readout. The low-cost ARAD will find immediate application by DTRA to equip large numbers of personnel and outfit points of entry with nuclear and radiological detection systems for identification of RDDs and INDs.

Title:Low Cost Manufacturing Process for Sodium Iodide Detectors
Abstract:An unconventional, continuous, and flexible manufacturing process is proposed for the production of sodium iodide detectors. The steps of crystal growing and substantially simplified detector machining are integrated into one streamline process based on proven techniques with minimal capital investment. This new production process will drastically reduce the manufacturing cost. A leading commercial collaborator will evaluate the performance of prototype detectors prepared according to specifications to replace single crystal sodium iodide detectors (reference detectors) in its popular radiation detection system. Preparing prototype detectors as replacement detectors will help to jump-start the commercialization process once the new detectors meets the performance specified by the collaborator. Critical technical data, including acceptable detector performance specifications established in Phase I will guide the Phase II pilot production of low cost sodium iodide detector, and guide the collaborator­_s development of low cost electronics and detection systems. In addition, the flexibility of the new integrated production process permits new detector designs and innovative applications.
