High-resolution scintillation crystals and crystal arrays are important components of current and future handheld and arrayed detectors (used for DOD/DTRA applications), and scintillation spectrometers (routinely used in high energy physics research, medical imaging, diffraction, homeland security, nuclear waste clean-up, nuclear treaty verification and safeguards, and geological exploration). Un ...

SIMOX (Separation by Implanted Oxygen) technology achieves total dielectric isolation of active device regions from the substrate and reduces the collection path for ionized charges via the built-in buried oxide which restricts charge movement. Advances in SIMOX technology include radiation hardened memories and gate arrays for space applications, ULSI DRAMs for low voltage operation, thin film SO ...

THE BUILT-IN BURIED OXIDE OF SIMOX SOI MATERIAL HAS PROMOTED RECENT ADVANCES IN RADIATION-HARDENED, AEROSPACE, AUTOMTIVE, AND COMMUNICATIONS APPLICATIONS. A SIGNIFCANT ISSUE RELATED TO THE USE OF SIMOX TECHNOLOGY IS THE CAPABILITY OF THE SI AND BURIED OXIDE LAYERS TO SUPPORT ADBANCED CMOS AND BIPOLAR CIRCUITRY. RECENT TECHNIQUES FOR SILICON AND BURIED OXIDE DEFECT DENSITY MEASUREMENTS SHOW THAT FU ...

A DYNAMIC SCENE PROJECTION SYSTEM IS PROPOSED WHICH CAN SIMULATE MULTI-SPECTRAL SCENES IN THE ULTRAVIOLET, VISIBLE, AND NEAR-THROUGH LONG-WAVE INFRARED WAVELENGTH BANDS. IT IS BASED ON ALIGHT VALVE TECHNOLOGY WHICH USES CRT ELECTRNICS TO DRIVA A DENSE ARRAY OF DEFORMABLE MIRRORS. THIS LIGHT VALVE, CALLED AN ELECTRON BEAM-ADDRESSED MEMBRANCE MIRROR LIGHT MODULATOR (EMLM), IS A MATURING TECHNOLOGY W ...

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 ...

Until now gamma radiation detection has required large single crystals of sensitive materials that are difficult to produce consistently on an industrial scale. In collaboration with a research group at the University of Texas at Arlington, Agiltron proposes to develop a new class of nanocomposite scintillator materials. The radiation detection characteristics of the synthetic nanoparticles in the ...

The Defense Nuclear Agency hase undertaken several related programs to develop new technologies for countering the proliferation of weapons of mass destruction, including weapons which disperse dry spore biological agents. These initiatives require an increased understanding of the response o fthese agents and their surrogates to the environments generated by various weapons, including penetratin ...

The Ktech Team proposes a feasibility study of a fuel/air driven flux compression power unit (FCPU) for electric guns. Through variations of inductance gradients and through changes in scale, the proposed technology will be applicable to both electrothermal/chemical and electromagnetic guns. In the Phase 1 effort, we develop simulation models to predict the performance of the flux compression po ...
