Proximity electrode signal readout of semiconductor based radiation detectors is accomplished by measuring the charge induced on electrodes positioned close, but not electrically connected, to the detector material. This technology can be applied to high-purity Ge...

A Fast Pulsed Neutron Source for Time-of-flight Detection of Nuclear Materials and Explosives
AASC has built a fast pulsed neutron source based on the Dense Plasma Focus (DPF). The more current version stores only 100 J but fires at ∼10–50 Hz and emits ∼106n/pulse at a peak current of 100 kA. Both sources emit 2.45±0.1 MeV (DD) neutron pulses of ∼25–40 ns...
Development of a Phoswich Detector System for Radioxenon Monitoring
Measurement of radioactive xenon in the atmosphere is one of several techniques to detect nuclear weapons testing. For high sensitivity, some existing systems use beta/gamma coincidence detection to suppress background, which is very effective, but increases...
Radioxenon Measurements With the Phoswatch Detector System
Many of the radioxenon detector systems used in the International Monitoring System and in other applications employ beta/gamma coincidence detection to achieve high sensitivity. In these systems, the coincidence detection is implemented by requiring simultaneous...
High Rate Pulse Processing Algorithms for Microcalorimeters
Microcalorimeters, cryogenic radiation detectors measuring the energy of photons by the increase of temperature in an absorber, can achieve energy resolutions more than an order of magnitude better than HPGe detectors. However, due to the thermal nature of the pulse...
