The Department of Energy, through Brookhaven National Laboratory (BNL), is seeking proposals for the fabrication of Gallium Arsenide (GaAs) sensors, specifically strip and pixel sensors, as part of a competitive contract opportunity. The procurement involves the production of two GaAs wafers, each designed to accommodate multiple strip sensors and MMPAD pixel sensors, emphasizing the need for precise and miniaturized sensor technology for various research applications at BNL. Interested contractors must be registered under the NAICS code 334413 and are advised that the anticipated award date is around December 20th, 2024, with a three-month fabrication turnaround expected post-award. For further inquiries, interested parties can contact Cassandra (Cassie) Smith at csmith2@bnl.gov or by phone at 907-888-3142.
