5W Pulse Tube CryoCooler

The Department of Energy‑funded Fermi National Accelerator Laboratory is seeking a single, high‑performance pulse‑tube cryocooler assembly for its 3 MeV Project at the Illinois Accelerator Research Center. The cryocooler must meet stringent temperature, cooling‑capacity, size, power, and vibration‑control specifications and be delivered as a firm‑fixed‑price, fully assembled unit. This solicitation is a best‑value, “lowest price technically acceptable” award with no discussions anticipated. • Scope: Supply a complete 5 W @ 4.2 K pulse‑tube cryocooler (cold head, compressor, gas lines, vibration‑dampening bellows, instrumentation and power cables). • Technical Requirements: ≤ 4.2 K operating temperature, ≥ 5 W first‑stage cooling at 4.2 K, ≥ 30 W second‑stage at 45 K, ≤ 30 kW power consumption, specific dimensional limits, and compatibility with a mobile trailer envelope. • Procurement Terms: Firm‑fixed‑price, FOB Fermilab, Net‑30 payment, no deviations accepted, award without discussions, submission deadline October 28 2026 5 PM CDT.
