THE NEED FOR INCREASING THE SENSITIVITY OF SPACE-BORNE SENSORS WILL REQUIRE DEVELOPMENT OF LONG-LIFE, HIGHLY EFFICIENT HELIUM LIQUIFIERS. CONVENTIONAL HELIUM LIQUIFIERS EMPLOY A JOULE-THOMSON EXPANSION VALVE TO EXPAND THE HELIUM AT TEMPERATURES BELOW ABOUT 10 DEG K. IT HAS BEEN SHOWN THAT GAINS OF UP TO 30% IN OVERALL CYCLE EFFICIENCY CAN BE OBTAINED IF THE JOULE-THOMSON VALVE IS REPLACED BY AN EX ...

This research project involves the application, development, and commercial scale up of a process for the deposition of copper and copper barrier materials such as ruthenium, titanium, and other metals. This process could replace copper electroplating currently used to fill deep trenches and thin-film deposition in microelectronic circuit manufacturing. In addition, physical vapor depo ...

This proposal describes the application, development and commercial scale-up of a process successfully developed under EPA contract number EP-D-04-042 for the deposition of copper and copper barrier materials such as ruthenium, titanium and other metals. This process could replace CU electroplating currently used to fill deep trenches and thin film deposition in microelectronic circuit manufactur ...

Bearing failure in satellite applications is related to lubricant starvation rather than fatigue, and health monitoring systems for these applications must be able to observe subtle changes related to lubrication state. Phase I included an experimental study to identify candidate monitoring approaches, and the data collected confirmed that cage motion characteristics and instability are highly sen ...

Lithium oxyhalide batteries offer energy densities several times higher than thermal batteries. Like thermal batteries, lithium oxyhalide batteries have unactivated storage lives in excess of 20 years and are mechanically rugged. Some of the main advantages that lithium oxyhalide batteries offer are flat discharge voltage profiles and potentially long operating lives. However, battery performanc ...

Ultra-high performance multi-function RF electronics are required by the United States Department of Defense to enable next generation radar and sensor networks in response to an increasingly diverse array of threats to our military and our homeland. An elegant potential solution is that of gallium nitride (GaN) RF electronics, which has shown great promise on currently available yet foreign subs ...

The current methodology for testing the penetration resistance of textile materials to various chemical agents has a number of drawbacks, including significant uncertainties in the resulting data, inefficiency and expense, risk to test personnel, and limited range of test conditions. The objective of the proposed work is to apply unique computer models for textiles with accompanying experimental ...

THE PROPOSED PROJECT WILL DEVELOP MATERIALS AND SUPPORTING THERMAL TECHNOLOGY LEADING TO DESIGN OF HIGH POWER PULSE CONDUCTORS FOR SPACE APPLICATIONS. IN PHSE I WE WILL EVALUATE AN EM GUN SYSTEM, IDENTIFY ALTERNATIVE MATERIALS AND THERMAL APPROACHES FOR SELECTED COMPONENTS, AND IDENTIFY TECHNOLOGY REQUIREMENTS. COMPONENT DEVELOPMENT FEASIBILITY AND BENEFITS WILL BE DEFINED.

Solid State Scientific Corporation proposes an triangular barrier photodiode (TBPD) detector for use on a dual mode sensor. The TBPD will function as a passive low-light visible-SWIR imager at long range and as a 3-D LADAR sensor at short range. The TBPD has the advantage of increased optical gain with decreased incident power, making it very attractive for applications with weak target signals, ...

The projected cost for the Mentis Sciences, Inc., (MSI) prototype PAC3 radome is 1/6th of the total cost of the present system. A Pareto analysis of the current MSI process indicates that the two largest costs in radome production are the direct labor associated with fabrication and the cost of the raw materials. In Phase I MSI demonstrated that COTS paint spraying technology reduced the direct ...
