A new custom cryogen-free dilution refrigerator with base temperature of 17 mK and cooling power of 120 μW@100mK was developed in collaboration with the University of Roma, Italy; and Janis Research Company, Inc. (USA). The design is specifically geared for integrating with an existing telescope on alt-azimuth mount. The first lab-based test results show that the system is maintaining its design specifications in its tilted position up to as much as -20 degree and +50 degree from the cryostat vertical axis. © Published under licence by IOP Publishing Ltd.

Abstract
A new custom cryogen-free dilution refrigerator with base temperature of 17 mK and cooling power of 120 μW@100mK was developed in collaboration with the University of Roma, Italy; and Janis Research Company, Inc. (USA). The design is specifically geared for integrating with an existing telescope on alt-azimuth mount. The first lab-based test results show that the system is maintaining its design specifications in its tilted position up to as much as -20 degree and +50 degree from the cryostat vertical axis. © Published under licence by IOP Publishing Ltd.File | Dimensione | Formato | |
