The Department of Defense, through the United States Air Force Academy (USAFA), intends to award a firm-fixed-price single source contract to Bruker Biospin Corp for the acquisition of an X-Band Microwave Resonator. This specialized equipment is designed for electron paramagnetic resonance (EPR) and electron nuclear double resonance (ENDOR) microwave spectroscopy, with specific requirements including a resonant frequency of approximately 9.8 GHz and the capability to operate at cryogenic temperatures. The procurement is critical for advancing research in microwave spectroscopy, and interested parties are advised that this notice is not a solicitation for bids or proposals; however, they may submit documentation of their capabilities to the primary contact, John Perry, via email by August 18, 2025, at 10:00 MDT.
