Thermal batteries are employed in virtually every strategic defense and tactical weapon system. As systems capabilities continue to increase, future thermal batteries will be required to deliver higher power and energy in packages smaller and lighter than those available with baseline lithium-silicon (LiSi) / FeS2 technology. Although ENSER’s proprietary LiSi / cobalt disulfide (CoS2) system p ...

The impact of metal whiskers on the reliability of electronics has been exacerbated by environmentally-driven efforts to eliminate lead from tin plating and solders. Even exempt applications, such as military, are affected due to COTS. Foresite, Inc., a consultant, laboratory and test equipment development company, has a goal for the subject research, in collaboration with Purdue University, to ...

Stochastic parameterization of large scale models is becoming an important tool for evaluating climate predictability and for enabling accurate representation of effects of micro-scale and short time physics on long time climate statistics. The models currently used to evaluate climate risk do not incorporate these stochastic effects, but represent multi-year development and collaboration between ...

The overall goal of the Phase II effort is to develop the novel ultra-rapid chemical mechanical finishing (UCMF) process for SiC mirror manufacturing, and commercialize this process in collaboration with existing vendors using existing equipment infrastructure. Unlike glass and metallic systems, the high hardness and chemical inertness of SiC currently limit the finishing of SiC mirrors to mechani ...

A back-illuminated planar InGaAs photodiode tested to have 95% quantum effiiency (QE) at 1550 nm, area greater than 1 mm2, low capacitance (125 MHz) will be improved. Although the existing Phase I device exhibited bulk material dark current generation better than commercially available devices, the sidewall-generated dark current was found to dominate the noise equiva ...

A 128 x 128-format avalanche photodiode (APD) focal plane array (FPA), including a low-power dual-mode readout integrated circuit (ROIC) and low excess noise, high gain (M>1,200) will be developed for laser radar (LADAR) applications requiring reduced SWAP. The FPA gives LADAR seekers an advanced active tracking sensor capability, providing a sufficiently wide field of regard (FOR) to eliminate th ...

Thermal battery pellets must be manufactured to extremely tight weight and density tolerances. Currently, this production process is a rate-limiting step in thermal battery manufacture. Inspection of pellets is currently performed manually, slowing the

JRD, Raytheon, and Tuskegee University have successfully completed the Phase I effort for design and development of an advanced solid state cryocooler for infrared sensor components. In addition, it was decided that the lowest-risk path forward for Phase II is the two-stage hybrid pulse tube / Joule-Thomson design. These initial calculations predict that efficiency potential of the solid state c ...

Existing approaches to guidance and estimation for intercept of maneuvering targets are often dependent on assumed models of maneuvering target behavior. We have shown in Phase I that intercept lethality can be dramatically reduced when an interceptor guidance strategy optimized for a specific maneuvering target type encounters a target whose behavior differs from that of the assumed model. We th ...
