Diode-Pumped Alkali Lasers (DPALs) have great potential for high-energy lasers. Proper design of these systems is challenging because many interrelated processes impact their performance, and critical kinetic rate coefficients are not well known. In response, our team is developing a comprehensive physics-based analysis/design tool, and experimentally determining key kinetic rate coefficients. The ...

We propose to develop a high-performance longwave infrared focal plane array (FPA) based on Type-II InAs/(In)GaSb strained-layer-superlattice (SLS) technology and deliver it packaged in a portable handheld CAMERA. In Phase 1, a matrix of recipes was designed and grown, several wafers were processed, arrays were fabricated and characterized, and material and process issues identified. In Phase 2, ...

Creare is developing a novel technique for forming biaxially oriented thin and thick films of high temperature superconductor YBa(2)Cu(3)O(x) on non-lattice matched substrates. These films should display high critical current densities because they will avoid the weak link problem that occurs between misaligned grains. Presently, the only effective means of achieving biaxial alignment is to either ...

Creare is developing an innovative capillary-based evaporator component for direct cooling of advanced electronic modules and for interfacing with capillary pumped thermal management loops for spacecraft. A reentrant capillary structure design will increase by an order of magnitude the pumping capacity of the capillary surface. Compared with current porous wick evaporators, this evaporator will ha ...

Sioux Manufacturing Corporation will develop a novel processing method for carbon-carbon composites manufacture with reduced processing time and costs. Current carbon deposition processes are unacceptably slow and expensive. The new feature of our process is the deposition of iron oxide onto the carbon filters to catalyze the deposition of carbon from methane. Laboratory tests have shown that this ...

THE OBJECTIVE OF THE PHASE II PROJECT IS TO EXPERIMENTALLY DEMONSTRATE THE PERFORMANCE OF SMALL STIRLING CYCLE CRYOCOOLER WITH INNOVATIVE DESIGN AND CONSTRUCTION FEATURES. THE EFFORT ENTAILS DESIGN AND DEVELOPMENT OF COMPONENTS, INTEGRATION INTO AN ENGINEERING MODEL CRYOCOOLER, AND TESTING OF THE CRYOCOOLER FOR PERFORMANCE AND ENDURANCE. ANTICIPATED BENEFITS OF THE INNOVATIVE DESIGN INCLUDE FIVE ...
