Test Report on the Qualification Program for the One-Quarter (1/4) Watt Split Stirling Common Module Cryogenic Cooler.

Abstract

This report describes the tests performed and the results obtained by CTI-CRYOGENICS from conducting a qualification program designed for a 1/4 Watt Split Stirling Cryogenic Cooler. Qualifications testing included evaluation of the 1/4 Watt Cryogenic Cooler under the following test conditions: low, room and high ambient temperature tests (-40 C, +23 C, +71 C); temperature shock testing (-54 C, +71 C); mechanical vibration testing; mechanical shock testing; audible noise testing; and reliability demonstration testing. The cryogenic cooler design consisted of a motor/compressor assembly, interconnecting stainless steel capillary tubing, and a remote expander assembly. Nominal operating voltage applied to the units was 17.5 VDC with a maximum input power of 35 watts. The cryogenic cooler assembly did not exceed the maximum weight limit of 2.5 pounds. Keywords: Cryogenic Refrigerator; Split Stirling; Cryogenic Cooler; 1/4 Watt Cooling System;Remote Expander; Compressor/Motor Assembly; Common Module Cooler.
