NASA's National Aeronautics and Space Administration (NASA) intends to procure the Kimball Physics EMG-4212 Electron Gun along with its matching EGPS-4212 Power Supply through a sole source contract with Kimball Physics Inc. This specialized equipment is designed as a modular subsystem compatible with vacuum systems, primarily for conducting analog experiments that simulate physical processes on airless celestial bodies, particularly focusing on space weathering studies related to the Moon in support of NASA's Artemis missions. The installation will take place at the Building 34 planetary magnetospheres laboratory at NASA's Goddard Space Flight Center in Greenbelt, Maryland, highlighting its significance to ongoing space exploration efforts. Interested organizations must submit their capabilities and qualifications in writing to the primary contact, Felecia Lorraine London, by 12 Noon Eastern Standard Time on January 22, 2025, to be considered for this procurement.
