Position-Sensitive Radiation Detector


Executive Summary


Gaseous ionization detectors are capable of measuring the energy and location of ionizing radiation. MSU researchers have developed an improved method of integrating multiple detection methods into a single parallel plate detector. By a novel means of arranging these various sensing methods, the x, y, and z coordinates of the ionizing radiation as well as the deposited energy and time are determined.


Description of Technology


This technology is the integration of a scintillator and a gaseous ionization in a dual mode parallel plate detector.  The perimeter of the detector is lined with scintillation light photo-sensors modified with segmented light sampling.  The segmentation of the photo-sensor light sampling allows improved resolution of the x, y coordinates of the impeding radiation.  This detector is applicable  to a diverse range of applications, including use in particle accelerator based research and industrial and medical radiation technologies.
