Design and performance of a portable helium 3 cryogenic system for ground based instrumentation.

Author(s) : VERVEER J., RANDO N., ANDERSSON S., et al.

Type of article: Article

Summary

The authors report on the design and performance of a complete ground based cryogenic system consisting of a helium 3 cryosorption refrigerator, and designed to cool a 6 x 6 element detector array of tantalum based superconducting tunnel junctions (STJs). The refrigerator provides an operating temperature of 330 mK, with a hold time in excess of 7 h. The system is designed to be portable, to provide a very stable focal plane, and to minimize the use of magnetic materials.
