Adelphi Technology Inc.

Adelphi Technology Inc., based in Redwood City, California, manufactures neutron generators, neutron optics, and advanced detection systems for federal research, medical, and defense applications, operating exclusively as a prime contractor on small-business set-aside and full-and-open federal contracts and grants. The company is a for-profit manufacturer with a small-business profile that competes predominantly under Total Small Business set-asides across SBIR and STTR programs, though it also wins full-and-open procurements from specialized agencies with unique technical requirements.

Adelphi's capability portfolio centers on compact and high-output neutron generator development, neutron scattering and diffraction instrumentation, advanced detection systems, and specialized scientific equipment for nuclear materials research, medical therapy, and counter-WMD applications. Recent representative work includes a $1.5 million Phase 2 R&D contract from the Department of Homeland Security's Countering Weapons of Mass Destruction Office (awarded August 2024, completing July 2027) for advanced neutron-based detection and mitigation technologies; a $500 thousand National Cancer Institute SBIR Phase I award (awarded September 2025) for a compact neutron source targeting pontine glioma therapy; a $997 thousand Department of Transportation SBIR Phase II award (completed July 2025) for a compact broadband leak detector for autonomous vehicles; a $405,175 Air Force Institute of Technology full-and-open purchase order (May 2025) for a high-output neutron generator supporting nuclear engineering education; and a $200 thousand Department of Energy Office of Science project grant (July 2024) for a powder neutron diffractometer to test irradiation effects in nuclear fuels and materials.

Customer concentration clusters heavily within the Department of Energy and its Office of Science. The top five funding entities by award count (Department of Energy Office of Science with 12 awards, Department of Energy with 11 awards, and Department of Homeland Security, Department of the Army, and Department of Agriculture with 3, 3, and 2 awards respectively) account for 53% of recent awards. When ranked by potential value, the picture shifts modestly: the Department of Homeland Security's Countering Weapons of Mass Destruction office, Defense Advanced Research Projects Agency, and Department of Transportation anchor the top-value positions, with these top five entities representing 83% of combined potential value across all awards. This divergence reflects Adelphi's dual posture — high award volume in DOE's smaller research grants paired with deeper dollar exposure in DHS and DoD R&D contracts.

Adelphi operates exclusively as a prime contractor; the vendor portfolio contains zero subcontract awards across the past thirty years. The company competes across small-business SBIR and STTR vehicles (the majority of its award volume) and selectively on full-and-open federal R&D procurements where its proprietary neutron technologies create competitive advantage. Across 59 total federal awards tracked in the source data spanning 1994 to February 2026, primary NAICS categories reflect research and development in physical, engineering, and life sciences (nine and seven awards respectively) and analytical laboratory instrument manufacturing (four awards). Recent activity has flattened — four awards each in 2022 and 2023, declining to three in 2024 and two in 2025 — with only one award recorded in 2026 through February. Two awards (combined potential value $3.3 million) reach ultimate completion within the next twenty-four months and represent recompete exposure.

Service Contract Inventory data covering FY2022–FY2024 captures limited federal services activity, with $483 thousand in invoiced revenue (prime only) recorded in FY2024 across 1.5 FTEs. SCI-reported government-paid hourly rates across prime service contracts ran from approximately $187/hr at the tenth percentile to $506/hr at the median and $824/hr at the ninetieth percentile, reflecting a mix of technical labor and specialized scientific support. The sub-engagement signal is minimal — an average of 4% of contractor hours performed by named subcontractors across prime contracts, with one named subcontractor reported. The vendor's federal work is dominated by product development and R&D instrumentation delivery rather than ongoing federal services, which explains the low SCI footprint and the minimal sub-reliance.
