Title: A cryostat to hold frozen-spin polarized HD targets in CLAS. HDice-II

Abstract

The design, fabrication, operation, and performance of a helium-3/4 dilution refrigerator and superconducting magnet system for holding a frozen-spin polarized hydrogen deuteride target in the Jefferson Laboratory CLAS detector during photon beam running is reported. The device operates both vertically (for target loading) and horizontally (for target bombardment). Moreover, the device proves capable of maintaining a base temperature of 50 mK and a holding field of 1 Tesla for extended periods.
