"Reflex triode bremsstrahlung sources potentially provide warm X-ray sources (20 keV to 500 keV), capable of generating high doses (~10 cal/g gold) over exposure areas of ~20 cm2. This needed capability allows experimental verification of warm X-ray inducedthermomechanical response, SGEMP, and box IEMP models for achieving component and system certification to hostile environments.In a reflex trio ...

The purpose of the VMIS is to allow manufacturers the luxury of testing and perfecting manufacturing plans long before a single machine tool is turned on and resources are committed. The VMIS will allow the user to select an available machine tool and an available inspection device, specify a proposed inspection plan and a dimensional analysis procedure, and then build and inspect hundreds (or ev ...

A solution to the need for OD 3 to OD 10 neutral density filters in the infrared (2 to 25 um) with flat wavelength dependence is suggested using submicron thickness polymer films as substrates for multi-layer or co-deposited metallic alloy coatings. Initial studies used Lexan and although they showed feasibility, a stronger and more temperature resistant ultrathin substrate such as polyimide film ...

This project will advance the state of the art of ultrahigh-pressure (UHP) jet machining technology. Existing technology uses water as the working fluid that accelerates abrasive particles in high-velocity, highly coherent jets. Despite successful demonstration and industrial utilization of the technology in cutting, cleaning, drilling, turning, milling, and surface-preparation operations, it re ...

INTEGRATED CIRCUIT (IC) PRODUCTION LINES OPERATING UNDER MIL-I-38535 HAVE RADIATION HARNESS ASSURANCE (RHA) AND RELIABILITY DESIGNED AND BUILT INTO THEIR TECHNOLOGY. HARDNESS AND RELIABILITY ARE MAINTAINED BY APPLYING STATISTICAL PROCESS CONTROLS (SPCS) TO TEST STRUCTURES FABRICATED ALONGSIDE PRODUCT MICROCIRCUITS. MEASUREMENT AND DATA REDUCTION TECHNIQUES PRESENTLY EMPLOYED ARE SLOW AND COSTLY AN ...

THE RAPID AND ACCURATE MEASUREMENT OF INTERNALLY THREADED HOLES IS ONE OF TODAY'S MORE DIFFICULT MEASUREMENT PROBLEMS. THIS IS PARTICULARLY TRUE IN LIGHT OF THE RECENTLY ADOPTED FASTENER QUALITY ACT (PL 101-595/HR3000) AND MIL-SPEC 7742D FOR CLASS 3 SAFETY-CRITICAL FASTENERS. QUEST HAS PREVIOUSLY DEVELOPED A NUMBER OF MINIATURIZED ELECTRO-OPTIC-BASED MEASUREMENT SYSTEMS THAT WOULD BE ADAPTABLE FOR ...
