Comprehensive Testing of a Neon Cryogenic Capillary Pumped Loop

摘要

This paper describes a comprehensive test program of a cryogenic capillary pumped loop (CCPL) using neon as the working fluid in the temperature range between 30K and 40K. The test article was originally designed to be used with nitrogen in the 70K to 100K temperature range, and was refurbished for testing with neon. Tests performed included start up from a supercritical state, power cycle, sink temperature cycle, heat transport limit, low power limit, reservoir set point change and long duration operation. The neon CCPL has demonstrated excellent performance under various conditions.
