SiPM Readout System

Fermi National Accelerator Laboratory (Fermilab), a civilian agency under the Department of Energy, is soliciting firm-fixed price proposals for a Silicon Photomultiplier (SiPM) Readout System consisting of electronic components for an Underwater Muon Detector. The procurement requires 62 64-Channel Citiroc Units and 10 Collector Boards designed to precise technical specifications including dual-gain sensitivity, 13-bit A/D conversion, 0.5 nanosecond time resolution, and support for both spectroscopy and timing modes. This is a best value source selection where the award will be made to the lowest-priced technically acceptable offeror, with the government intending to make an award without discussions. All proposals must include a completed RFP page, SARC (Subcontractor Annual Representations & Certifications) form, and PUR-466 (Proposal Certifications) form, with proposals exceeding $10,000 requiring both the SARC and PUR-466 documents. The proposal deadline is 5:00 PM Central Time on November 13, 2025, with all freight charges to be included in the quotation.

This solicitation carries no set-aside designation and represents an open competition. The 72 total units will be shipped to Fermilab Receiving Warehouse 2 in Batavia, Illinois, with all delivery and logistics coordinated through Fermi Forward Discovery Group, LLC (FFDG), the managing entity under Department of Energy prime contract DE-AC02-07CH11359. While no specific award value range is disclosed in the solicitation notice, interested vendors should anticipate that proposal requirements escalate at the $10,000 threshold and potentially at higher dollar values of $150,000 and $550,000 based on the tiered certification structure outlined in the PUR-466 form. Prospective offerors with questions should contact Spencer Keske, Procurement Specialist III, at skeske@fnal.gov or 630-840-3323, with the procurement following FFDG General Terms and Conditions for Commercial Products and Commercial Services dated August 2025.
