REQUEST FOR INFORMATION (RFI) No. 80GSFC21001RFI NASA/Goddard Space Flight Center (GSFC) would like to survey the market for a Model BF-LD250S cryogen-free dilution refrigerator system. The principal purpose of this requirement is to provide, install, and commission the LD250S dilution refrigerator for NASA/GSFC. NASA is developing a cryogenic detectors, which will require a sub-Kelvin cryogenic systems for testing. This is in support of the development of millimeter, sub-millimeter, and IR detectors. The purpose of this RFI is to survey vendor capabilities to meet the NASA’s strategic research and development mission requirements. This request is for information and planning purposes and feasibility of the requirements. The requirements for the base LD250S system are provided by the following specifications: Base temperature < 30 mK Cooling power > 250 uW at 100 mK Cooling power > 360 uW at 120 mK System configured for 115V 60Hz main voltage System comes with Cryomech PT415-RM pulse tube Pulse tube voltage 200/230V 3Ph 60Hz Temperature controller provided with 8-channel resistive temperature measurement Four temperature control heaters Additional included options: 4K heater kit Vacuum can and radiation shields to have removable bottoms and side access port 6 SCuNi-CuNi coaxial cables from room temperature to the mixing chamber 1 DC wire set, Cu, 35AWG wire, 12 twisted pairs, room temperature to 4K 1 DC wire set, Cu, 35AWG wire, 12 twisted pairs, room temperature to 4K with intermediate breakout at 50K flange. 1 DC wire set, PhBr, 35AWG wire, 12 twisted pairs, room temperature to mixing chamber 1 DC wire set, PhBr, 35AWG wire, 12 twisted pairs, room temperature to mixing chamber with intermediate breakout at still flange. 2 optical fibers, single-mode 1550nm FC/PC-FC/PC installation set from room temperature to mixing chamber.
