Microwave Technologies Incorporated is proposing the development of a very compact radio-frequency (rf) electron beam accelerator which appears to be well-suited for BMDO's directed energy applications. This novel concept employs a single short rf cavity operating in circular polarization to accelerate a low-energy ma ~netized pencil beam to energies that range from 2 to 10 MeV. The proposed accel ...

In this Phase I study, we will demonstrate high power, continuous wave (CW) single spatial mode laser action at the 1 um wavelength. There are two innovative aspects in our proposal: the incorporation of commercially available very high power, not necessarily single mode, semiconductor laser diodes as pump sources; and, a novel single mode fiber, doped with the appropriate rare earth ions. The pum ...

Brimrose proposes to produce an improved material for optical power l miting at near infrared wavelengths to protect sensors against jamming and to build a prototype device. The proposed material, vanadium doped cadmium telluride, is relatively new and will be used to fabricate an electro-optic power limiter (EOPL). This approach of using a doped II-VI semiconductor for power limiting was first de ...

A true single longitudinal mode distributed feedback (DFB) fiber laser will be developed. The first and only, a preliminary demonstration of this laser has just been published, but it is not truly single frequency. We shall develop and commercialize the world's first DFB fiber laser with Bragg gratings written directly onto the core of the fiber. We shall implement an innovative external technique ...

Current CRT phosphors rely upon 3-12 micron sized semiconductor grains to convert the electron beam emitted by the cathode into light. These phosphors suffer from low conversion efficiencies (25%), and efforts to improve these systems over the past few decades by altering the stoichiometry have resulted in only minor improvements. Quantum Dot Phosphors(TM) (QDP(TM)) of doped and undoped II-VI semi ...

The quality and durability of coatings produced by virtually all thermal spray techniques could be improved by, among other things, increasing the velocity with which coatings particles impact the coated surface and by better control of the chemical and thermal environment seen by the particles during flight. A new and innovative approach to thermal spraying is proposed that can increase coating p ...

CURRENT STUDIES CONCENTRATE ON GLOBAL POSITIONING SYSTEM (GPS) AS A SPACECRAFT ATTITUDE DETERMINATION TOOL. TWO GPS ANTENNAS RECEIVING THE SAME SIGNAL CAN COMPARE THEIR RELATIVE PHASES TO DETERMINE THE ANGLE BETWEEN THE TWO ANTENNAS AND THE GPS SATELLITE. BY COMPUTING THE ANGLE TO THREE OR MORE SATELLITES, THE COMPLETE INERTIAL ORIENTATION MAY BE DETERMINED. APPLYING ADVANCES IN GPS INTERFEROMETRY ...

Global production and use of ceramic capacitors exceeds several hundred million units per day. With the projected growth in demand for more demanding electronic products, electronic vehicles and related technologies, the need for more reliable, higher energy density, higher power density, higher breakdown strength, efficient ceramic capacitors can not be overstated. Multilayered ceramic capacitors ...

The very high cost of forming finished parts from advanced engineering ceramics severely limits their widespread use. Superplastic forming can help address this technology barrier. Unfortunately, until recently, nothing could be done to induce superplasticity in ceramics. This program will utilize recent breakthroughs that now reproducibly suggest the potential of superplastic forming. It is ant ...

A NEW RANGE-DOPPLER LASER-RADAR FOR SOLID TARGET DETECTION WITH 1 M RANGE AND 0.5 M/S VELOCITY RESOLUTION AT RANGES UP TO SEVERAL HUNDRED KILOMETERS IS PROPOSED. A MULTI-BEAM AGILE SCANNER FEATURE WILL PROVIDE ANGULAR DISCRIMINATION ACROSS A LARGE FOV IMAGE WITH A WIDE FIELD OF REGARD. RANGE RESOLUTION, DOWN 1O 1 M, AND VELOCITY RESOLUTION DOWN TO 0.5 M/S (WITH A DYNAMIC RANGE UP TO 11,000 KM/S) A ...
