Euclid Beamlabs LLC

Euclid Beamlabs LLC, based in Beltsville, Maryland, operates as a small business prime contractor delivering advanced research and development in charged particle beam physics, materials science, radiation-hardened electronics, and accelerator technologies to federal research and defense agencies. The vendor holds a 100% prime contractor footprint across 36 federal awards with no subcontractor engagement; it competes under full-and-open competition and total small business set-asides, with no recurring set-aside designation driving its prime portfolio.

Euclid Beamlabs' capability portfolio centers on SBIR Phase I and Phase II development work, including high-pressure high-temperature diamond substrate growth for radiation-tolerant applications, single-event-burnout hardened high-power diamond devices, deployable X-band accelerator systems (5–15 MeV), electronic brachytherapy sources for cancer radiotherapy, and large-area photocathode development. Representative prime work includes a $1.76 million SBIR Phase II definitive contract from the Air Force Research Laboratory (awarded May 1, 2024) for high-pressure high-temperature growth technology targeting nitrogen-vacancy diamond substrates; a $1.25 million SBIR Phase II award from AFRL (August 14, 2024) for a deployable high-current X-band accelerator system with ultimate completion in November 2026; a $910,986 SBIR Phase II award from the Shared Services Center (June 9, 2023) for single-event-burnout hardened diamond devices with completion through September 2026; and a $206,484 Department of Energy Office of Science Project Grant (July 10, 2023, CFDA 81.049) for development of a non-radioisotopic gamma-ray calibration source.

Customer concentration is heavily weighted to research and development funding agencies. The Department of Energy Office of Science leads by award count (18 awards), followed by the Air Force Research Laboratory Materiel Command (4 awards, $3.3 million combined potential value), and the Department of Energy broadly (3 awards). By dollar value, the Air Force Research Laboratory dominates ($3.3 million), followed by the Defense Advanced Research Projects Agency ($2.9 million on a single OT IDV), NASA's Shared Services Center ($1.1 million across 2 awards), and the Department of Homeland Security Countering Weapons of Mass Destruction ($996 thousand). These five customers account for 96% of combined potential value across the portfolio.

Euclid Beamlabs recently secured two significant vehicle positions. On January 21, 2026, the Missile Defense Agency awarded a multiple-award IDIQ titled Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) with a multi-billion-dollar ceiling and ultimate completion in December 2035, supporting research and development, prototyping, systems engineering, weapon design, test and evaluation, and modernization across air, missile, space, cyber, and hybrid defense domains; an initial $500 delivery order was issued the same day. On July 1, 2025, the Defense Advanced Research Projects Agency awarded an Other Transaction IDV with a $2.9 million ceiling for Large Area Photocathode research and development, aligning directly with Euclid Beamlabs' core photocathode competency.

Activity has remained modest and stable across the five-year window in the source: one award in 2022, three in 2023, three in 2024, three in 2025, and two in 2026 (most recent January 2026). Two awards totaling $2.2 million in combined potential value face completion within the next twenty-four months, presenting recompete exposure in the SBIR and small-agency research pipeline. Service Contract Inventory reporting, covering only federal service contracts above $150,000 and excluding goods and classified work, shows SCI-reportable invoicing of $213 thousand in FY2023 across 0.5 FTEs and $395 thousand in FY2024 across 1.6 FTEs on a single prime SBIR Phase II contract; hourly rates on these SCI-reportable records ranged from a median of $171.33/hr to $213.44/hr at the 90th percentile. The vendor self-performed all reported hours with no subcontractor utilization. SCI data represent only a narrow slice of Euclid Beamlabs' federal activity — most of its awards fall below or outside the SCI reporting threshold — and do not capture total company revenue or workforce scale.
