Background

Currently, there are numerous applications in which high-energy resolution radiation detectors are needed to properly yield data with the fidelity required by the user. Proper measurement of an emitted or transmitted particle or photon energy is necessary to produce the science or application that the user requires. Scenarios in which high-fidelity (i.e. high energy resolution) data is required by users generally require expensive and/or complex and sensitive detectors to generate their required data. One such example is with gamma-ray spectroscopy, where high-purity germanium (HPGe) detectors are required due to their extremely good gamma-ray energy resolution. However, there are several complications to HPGe. Their detection efficiency is often very low. Their inability to handle high-count-rate situations (such as in high radiation fields) leads to high dead time and often degradation of the quality of data (i.e. peak deformation) and their requirement to be cooled to cryogenic temperatures limits the cases/locations of their deployment.

Technology Overview

Researchers at Idaho National Laboratory have developed a solution that offers the ability to resolve high-resolution data from low-resolution detectors (such as high-purity germanium detector-like data from much less expensive and simpler sodium iodide detectors). This solution would allow for the use of higher-efficiency and higher-rate capable detectors while also seeing at least 10x reduction in cost per detector.

Stage of Development

TRL 5, technology has been demonstrated in a laboratory environment with real-world conditions.
