AMERICAN SCIENCE & ENGINEERING INC

American Science & Engineering Inc. specializes in the design, manufacturing, and sustained operation of high-performance X-ray inspection systems, particularly the Z-Portal series, for cargo, vehicle, and personnel screening. The company provides end-to-end support including preventative and corrective maintenance, system upgrades, operator training, and full contract closeout services for mission-critical radiation-based detection platforms. Their technical expertise centers on irradiation apparatus engineering, precision X-ray imaging systems, and the integration of radiation safety protocols with ruggedized field-deployable hardware. A key differentiator is their deep domain knowledge in maintaining and sustaining complex, government-operated scanning systems under demanding operational conditions, ensuring continuous availability and regulatory compliance. The contractor maintains a strong, long-standing relationship with the Department of Homeland Security, delivering sustained maintenance and upgrade services for deployed X-ray inspection systems. They also support the Department of Defense with vehicle and cargo inspection infrastructure and the Department of State with international deployment and lifecycle management of screening equipment. These engagements reflect a pattern of repeat, mission-critical support rather than one-time procurement, indicating trusted operational partnerships. Their primary industry focus is irradiation apparatus manufacturing, where they engineer and sustain non-intrusive inspection systems using advanced X-ray and gamma-ray technologies. Secondary work in electronic equipment repair and physical sciences R&D reinforces their role as a technical services provider for specialized sensing and detection platforms. They are positioned as a niche supplier of hardened, field-deployable radiation detection systems for high-security government applications. Based in Billerica, Massachusetts, American Science & Engineering Inc. operates as a small business under the 2L entity structure. While no formal government certifications are listed, their consistent performance on sensitive national security contracts demonstrates proven reliability and technical competence within the federal defense and homeland security market.
