LumArray, Inc. proposes under Phase II to further improve its maskless zone-plate-array lithography system, to meet the requirements of manufacturers of custom chips for the DoD. Under Phase I, a prototype alpha tool was developed, the ZP-150ATM. Under Phase II we will develop and demonstrate a beta tool, the ZP-150BTM, which will have features beyond those available on the alpha tool. Specificall ...

There is a critical need for revolutionary approaches for thermal management of 21st century semiconductor devices and hardware, such as advanced high performance computers, high-power laser diodes and solar cells for the conversion of sun light to renewable energy. The one limiting factor for all of the above extremely important and compelling technologies is waste heat management that can remove ...

Science Research Laboratory proposes to develop a pulsed, tunable mid-IR source with average power greater than 55 watts and high pulse repetition frequency (20 kHz). The program is divided into a baseline and two options. In the baseline program we will develop a continuous-wave laser operating at a wavelength of 2.1 microns with a power of approximately 120 watts. In the option programs, the 2.1 ...

Laser diodes (LD) have many desirable properties, e.g. small size and high electrical-to-optical efficiency. For ease of use, most applications require coupling the LD photons to an optical fiber. Attaching the LD-die to a heat-sink is a key packaging procedure. The heat-sink material is generally copper since it is the lowest thermal-resistance metal but its CTE (coefficient of thermal expans ...

Alameda Applied Sciences Corporation (AASC) proposes to develop an all-solid-state, compact, portable, multi-gigawatt poer modulator for electron and ion beam diodes, high power microwave and x-ray sources. This modulator is based on Inductive Energy Store (IES) using an array of Diamond Opening Switches for power compression. Because power amplification using IES requires a much smaller volume ...

Alameda Applied Sciences Corporation (AASC) proposes to develop a new type of interferometer that is compact and portable and can be used to make in-situ measurements of gases and plasmas. This interferometer uses polarization maintaining optical fibers and diode lasers to duplicate the capabilities of existing Mach-Zender interferometers that use dicrete optical elements such as mirrors, lenses ...

Alameda Applied Sciences Corporation (AASC) proposes a three phase effort with the ultimate goal of producing a marketable diamond switch suitable for several pulsed power and other applications in the defence arena. The presently used spark gaps have several drawbacks including switch jitter, large and variable inductance, lifetime and physical size. A low inductance solid-state switch capable ...

Alameda Applied Sciences Corporation (AASC) proposes to develop two components of a three-component, survivable debris shield for large area test exposures to cold (1-5keV) x-rays. These elements also have commercial potential in accelerators and in radiography. The elements are: an ultrafast gas curtain designed to be located close to the x-ray source to deflect plasma debris as well as ~um siz ...

Alameda Applied Sciences Corp proposes to develop a fast pulse, portable, fast neutron source to detect SNM in the field. Our source offers a 20ns neutron pulse with a repetition rate up to 1kHz. The goal is to develop a source with 1000hrs of continuous operation at 1E8 n/s. The Ph I program will demonstrate the critical features of the source including pulse width, reproducibility and neutron yi ...

This proposal investigates the feasibility of using a systems analytic approach to model the critical processes supporting proliferation of weapons of mass destruction. It uses as a framework for synthesis a previously developed systems analysis model of biological weapons proliferation. The proposed approach consists of four tasks to: 1) extend the BW analytical process to encompass all WMD, 2) d ...
