Development of a CZT-Silicon Detection System in Support of the Comprehensive Nuclear-Test-Ban Treaty

Creator:

Alhawsawi, Abdulsalam M.

Abstract:

The Comprehensive Nuclear-Test-Ban Treaty (CTBT) bans all nuclear explosion tests for military or civilian purposes. The International Monitoring System (IMS) was established to verify compliance with the treaty. It consists of several monitoring stations that detect: seismic activities, hydrocoustic activities, infrasound waves, and radionuclide particles and noble gases. Radioxenon detection...

A Two-element CZT-based Radioxenon Detection System for Nuclear Weapon Test Monitoring

Creator:

Ranjbar, Lily

Abstract:

Detection of xenon radioisotopes (radioxenons) has proven to be an important method for detecting nuclear explosions and is particularly well suited for detecting undeclared underground testing. The radioxenon isotopes ¹³¹mXe (t₁/₂ = 11.934 d), ¹³³mXe (t₁/₂ = 2.19 d), ¹³³Xe (t₁/₂ = 5.243 d) and ¹³⁵Xe (t₁/₂ = 9.14 h)...

Real-time radioxenon measurement using a Compton-suppressed well-type phoswich detector for nuclear explosion monitoring

Creator:

Alemayehu, Bemnet

Abstract:

Radioxenon detection is a technique used to monitor nuclear explosion and verify the Comprehensive Nuclear-Test-Ban Treaty (CTBT). Because of an ultra-low concentration of radioxenon at radioxenon monitoring stations, radioxenon detection systems must have high sensitivity. This sensitivity is measured in terms of detector's minimum detectable concentration (MDC). It is required...

Dissertation
Prototyping a triple-layer phoswich detection system

Creator:

Duncan, Christopher L.

Abstract:

Multi-layer optically coupled scintillation based radiation detectors, known as phoswich detectors, have rapidly evolved in recent years. During the same time, digital signal processing has improved radiation discrimination accuracy and enhanced reliability, while reducing complexity and size of traditional analog signal processing methods. A new generation of high-speed radiation detectors...
