Purchase of a low temperature, low vibration helium cryo-cooler for ICEE facility

The NASA/NSSC has a requirement for the purchase of a low temperature, low vibration helium cryo-cooler for the ICEE facility. The cryo-cooler should be capable of a 9 K, or lower, minimum temperature and have a cooling power of 60 Watts or greater at 77K. The scope of work includes the delivery and installation of the cryo-cooler, as well as technical manuals and an installation kit. The period of performance shall be from award to 12/20/2026. The key features of the cryo-cooler include: * A minimum temperature of 9 K or lower * A maximum temperature of 355 K * Temperature stability of 3 mK or less * A cooling power of 60 Watts or greater at 77K * A low vibration design with displacement of the sample due to vibrations of +/- 5 nm * A temperature controller integrated with the cryostat * Interconnecting cables to the cryostat * A price that includes packing and shipping.
