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 ...

For ultra high speed applications in DoD satellite systems, devices and circuits fabricated from III–V semiconductor compounds offer significant advantages over silicon-based technology in terms of operating speed and power. However, the uncertainty in single-event-effect (SEE) response of compound technologies forces the use of empirically-based hardening techniques with penalties in increased ...

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 PROPOSED FIBLOC SENSOR PROVIDES AN ECONOMIC MEANS TO PROTECT, LITERALLY, MILES OF A PREFERRED PERIMETER REGION AGAINST UNAUTHORIZED INTRUSIONS. THE OPTICAL FIBERS EMPLOYED INT HE FIBLOC SENSOR PROPAGATE CW OR PULSED INFRARED LIGHT SIGNALS WHOSE TRANSMISSION AND/OR REFLECTION SENSITIVITY IS AFFECTED BY MECHANICAL PRESSURE SUCH AS WOULD BE PRODUCED BY THE DISTENSION OF SURFACED MOUNTED FIBERS AL ...

A batteryless and wireless sensor for intrusion detection and assessment of threats which requires no battery, external power or wiring is proposed. These types of sensors derive energy from passing vehicles or persons, and indicate their presence, location, speed, etc., via a self-generated short-range radio signal. These sensors require no maintenance, and can be inconspicuously placed in window ...

THE PHASE I EXPERIMENTAL EFFORT WILL DEMONSTRATE THE FEASIBILITY OF A FIELD WORTHY GROUND MOTION SENSOR TO REPLACE PIEZO-ELECTRIC ACCELEROMETERS FOR CONVENTIONAL EXPLOSIVES AND NUCLEAR TESTING. THE OUTPUT SIGNALS OF PIEZO-ELECTRIC ACCELEROMETERS MUST BE INTEGRATED TWICE TO DETERMINE GROUND MOTIONS. THIS PROCESS REDUCES SYSTEM ACCURACY AND MEASUREMENT BANDWIDTH. ADDITIONALLY, AS PIEZO-ELECTRIC SENS ...

THIS PROJECT DEMONSTRATES AN EFFECTIVE METHOD FOR RESOLVING THE PROBLEM OF TRANSIENT BACKGROUND PHOTON NOISE (TEMPORIAL REDOUT VARIATIONS) CAUSED BY AN INTERMEDIATE ALTITUDE (40 TO125 KM) NUCLEAR FIREBALL WHICH AFFECTS THE FUNCTIONS OF BMD OPTICAL SENSORS. THE OBJECTIVE OF THE PHASE I STUDIES IS TO:1) DEVELOP A PERMANENT DATA BASE FROM DIGITIZED IMAGE EN- HANCE ORIGINAL TEST FILM IN WHICH TO DEMON ...

Physitron proposes development of an x-ray/gamma-ray telescope that can be used for treaty verification and compliance testing. In particular, the x-ray/gamma-ray telescope can be mounted in the Open Skies Treaty aircraft to provide a capability of detect, characterize and identify nuclear weapons development work. Objectives of the development program include: (1) adapting an existing gamma-ra ...
