He-3 Dilution Refrigerator System

This contract pertains to the procurement of a He-3 Dilution Refrigerator System under solicitation number 1333ND24QNB680337, issued by the Department of Commerce's National Institute of Standards and Technology (NIST). The contract is designated as a total small business set-aside under NAICS code 333415, emphasizing the involvement of small businesses in fulfilling the requirements. The solicitation was posted on October 8, 2024, with a response deadline extended to July 11, 2024, at 3:00 PM. The contract scope involves the delivery and potential customization of a cryogenic system designed for advanced scientific measurements, with performance to be conducted at NIST's facilities in Gaithersburg, Maryland. An amendment to the original solicitation extends the response deadline and clarifies a technical detail regarding the cold stages of the system. Specifically, it addresses the inclusion of blanks for unused holes on the cold stages, which are features designed to accommodate various modular configurations. When certain holes are not utilized for a specific configuration, vendors are required to provide heat shields to cover these holes, preventing thermal radiation transfer between stages. This ensures the system's thermal integrity and performance. The amendment also includes a response to a vendor question about these holes, referencing relevant attachments for detailed specifications. The contract's point of contact includes Tracy Retterer and Forest Crumpler, who can be reached via email for further information.
