DTRA Phase I R&D for Domestic Growth of Large-Format CZT Crystals

The Defense Threat Reduction Agency is seeking research to establish domestic, scalable growth of large-format CZT crystals for radiation detection. - Government buyer: Defense Threat Reduction Agency (DTRA), Department of War (DoW), DTRA SBIR/STTR Program. - Opportunity: Phase I SBIR topic DTR27BZ02-NV006, focused on domestic scalable growth of large-format pixelated cadmium zinc telluride (CZT) crystals for advanced radiation detection. - OEMs and vendors: No OEMs, vendors, or commercial part numbers are identified. No finished detector systems or crystals are being purchased; this is an R&D opportunity. - Technical target: Nominal crystal dimensions are 44 × 44 × 15 mm for room-temperature gamma-ray detection and spectroscopy supporting WMD detection, nuclear forensics, and related missions. - Phase I work: Assess domestic and allied growth capabilities and material sources; design a growth and machining process; demonstrate at least one near-target crystal or scalable proxy; and characterize material uniformity, performance, supply-chain risks, yield, and commercialization potential. - Follow-on work: Phase II would refine and scale the process to produce multiple crystals, with independent characterization of a lot of at least three to five crystals or equivalent validated output. Optional Phase III may support pilot production and commercial transition. - Key requirements: Crystal growth must be U.S.-based, use traceable U.S. or allied materials, demonstrate reproducible quality and performance, and include a credible commercial transition path. - Funding and duration: Phase I is limited to seven months and a $250,000 base amount, excluding TABA. Follow-on Phase II may run up to 24 months with a $1,500,000 ceiling, excluding TABA.
