Specifications - Sources Sought Notice HPGe FY20.docx

This document outlines requirements for a high-purity germanium gamma ray spectrometer system and sources sought notice. The Defense Threat Reduction Agency requires a portable gamma ray spectrometer weighing less than 10 pounds with dimensions under 2500 cubic centimeters, capable of cryogenic cooling with a 3-hour maximum cooldown time. The system must achieve an energy resolution of at least 2.5 keV at 1332 keV, 10-12% efficiency relative to a 3"x3" sodium iodide detector, and operate within an energy range of 40 keV to 3 MeV. Responses to the sources sought notice must include company information and be submitted by the published deadline to be considered for a future solicitation for this tactical gamma ray detection requirement.
