Pulse shape discrimination applied to certain fast scintillators is usually performed offline. In sufficiently high-event rate environments data transfer and storage become problematic, which suggests a different analysis approach. In response, we have implemented a...

Development of a Phoswich Detector for Radioxenon Field Measurements
The Comprehensive Nuclear-Test-Ban Treaty Organization deploys a variety of radioxenon detection systems as part of its International Monitoring System to detect nuclear explosions. To achieve the high sensitivity required, the systems extract xenon from several cubic...
A 24-element Silicon PIN Diode Detector for High Resolution Radioxenon Measurements using Simultaneous X-ray and Electron Spectroscopy
The measurement of atmospheric radioxenon is an important tool for monitoring nuclear weapons testing. The development of new and improved xenon detection methods supports the monitoring program of the Comprehensive Test Ban Treaty Organization (CTBTO). In the current...
Proximity Electrode Signal Readout of High-purity Ge Detectors
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...
Radioxenon Measurements With a Coincidence Silicon Detector System
The radioxenon detectors currently used in applications related to nuclear explosion monitoring have a very high sensitivity to detect very small amounts of radioxenon. However, to better distinguish the radioxenon background created by nuclear power plants and...
