The Goddard Space Flight Center (GSFC) is seeking a vendor to supply specific filters necessary for the testing of superconducting detectors used in astrophysics and cosmology research. The primary objective is to develop cryogenic test facilities capable of illuminating these detectors at controlled wavelengths. The requested products include three lowpass and three highpass filters with edge frequencies around 3 and 6 THz, along with a lowpass blocking filter at 10 THz. These filters must be 50 mm in diameter, exhibit over 90% transmission in their passband, and effectively block over 99% of out-of-band power at cryogenic temperatures below 1 K. The performance verification will take place at the GSFC in Greenbelt, MD, with all filters to be delivered by January 1, 2025. This procurement is vital for ensuring that the detector technologies meet mission requirements for future space exploration initiatives.

NASA's NASA/NSSC is seeking to acquire custom lowpass and highpass filters specifically designed for cryogenic operations. The agency plans to issue a sole source contract to Celtic Terahertz Technology Limited, recognized as the unique provider of these filters. The procurement will be managed at the NASA Goddard Space Flight Center (GSFC) and will adhere to the commercial item procurement guidelines outlined in FAR Parts 12 and 13. The relevant NAICS code for this acquisition is 334516. Interested parties may submit their qualifications by 4:00 p.m. Central Standard Time on October 25, 2024. The government retains discretion over whether to proceed with a competitive procurement based on the submitted capabilities. Communications regarding this notice must be in writing, as oral communications will not be accepted. The applicable ombudsman for this contract is accessible via the provided NASA link. This initiative underscores NASA's commitment to sourcing specialized technologies essential for their operations.
