Pulsed High-power Laser Accelerators to Study radiation Hardening (PHLASH)
SBIR Opportunity Analysis
DARPA is seeking SBIR proposals for Pulsed High-power Laser Accelerators to Study radiation Hardening, focused on advancing compact laser-plasma acceleration technology for radiation testing of space microelectronics. The work centers on designing and building a prototype laser driver that can generate 50-MeV electron beams at greater than 100 Hz, with a path to scaling the system to 100 GeV and 1 kHz within a compact 250 m3 footprint. The effort emphasizes scalable system design, including beam-focusing optics, gas-target behavior at higher energies and repetition rates, and evidence of feasibility through prior compact LWFA design and supporting simulation and/or experimental data; the base period is structured around fixed payable milestones over 24 months, ending with a prototype demonstration and final scale-up design. Proposals are due May 13, 2026, under solicitation HR0011SB20254-13.
