The Department of Defense, specifically the United States Air Force, is seeking innovative solutions through the Small Business Innovation Research (SBIR) program to develop a system for the recovery, purification, and reliquefaction of neon gas for infrared focal plane array characterization. The primary objective is to create commercial products that enable users to recover and liquefy neon gas at a small scale (less than 10 liters per day), thereby reducing reliance on expensive and limited liquid neon supplies. This technology is crucial for maintaining the operational efficiency of infrared detectors, particularly in remote settings where access to cryogenic liquids is challenging and costly. The solicitation is currently closed, with the application due date having been on June 12, 2024.
