Passive Object Detection System

Imaging with X-rays and gamma rays is a long established technique. It is possible with recent technological advances that standard transmission radiography may be extended to self-radiography, where the natural radioactivity of the object itself and the surrounding matrix is used as the source of X-rays. Self-radiography is much more complex than traditional radiography, chiefly because it depends on a distributed, non-quantified, and low intensity source. Mirmar Sensor builds high-pressure xenon spectrometers. These detectors provide medium resolution, highly stable, very large, room temperature spectrometers. The work proposed here leverages on the extensive detector work, nuclear search work, and soil assay work done by the team at Mirmar Sensor. Also important to this project is the additional interaction information and the flexibility of configuration provided by Mirmar Sensor’s patented gridless HPXe technology.
