DTRA’s STTR topic seeks research and prototype development of compact, high-energy-density capacitors for portable pulsed-field X-ray generators.
- **Government buyer:** Defense Threat Reduction Agency (DTRA), DTRA SBIR/STTR Program, within the Department of War.
- **OEMs and vendors:** No OEMs, manufacturers, or vendors are named in the notice.
- **Requested prototypes:** 10 capacitors for Phase II Year 1 testing and refinement, followed by up to 10 compliant capacitors delivered in Year 2; no part numbers are specified.
- **Technical targets:** Maximum dimensions of 2 × 1 × 0.5 inches, 100 kV, 2 nF, 80% voltage-reversal tolerance, and more than 100,000 cycles. Voltage and voltage-reversal performance are the highest priorities.
- **Research and manufacturing work:** Phase I design selection and modeling, material-sample fabrication and testing, and a scalable manufacturing plan; Phase II process execution, optimization, and scale-up toward Technology Readiness Level 5; optional Phase III production scale-up.
- **Funding and schedule:** Phase I is generally up to $250,000 and 7 months; Phase II is limited to 24 months and up to $1.5 million. Phase III is optional, with no duration specified. The Phase I cap excludes Technical and Business Assistance (TABA).
- **Notable requirements:** The work is subject to ITAR or EAR export controls. The notice lists CMMC Level 1.
