Summary

This report describes the development of low vibration cooling systems with pulse tube (PT) cryocoolers. Generally, PT cryocoolers have the merit of lower vibration than GM cryocoolers. However, the cooling systems for a cryogenic laser interferometer observatory (CLIO), which is a gravitational wave detector, require sufficiently lower operational vibration than that of a commercial PT cryocooler. The required specification for vibration amplitude on cold stages is less than plus or minus 1 microm. Therefore, during the development of the low vibration cooling systems for CLIO, advanced countermeasures were introduced for commercial PT cryocoolers. The cooling performance and the vibration amplitude were evaluated.
