MODULAR PHOTON DETECTOR CRYOSTAT ASSEMBLY AND SYSTEM

摘要

Modular Photon Detector Cryostat Assembly and System In a photon detector system, such as a cryogenic gamma radiation detector cooled by a dewar, a vacuum-jacketed radiation detector is provided in a cryostat assembly. The detector can be used with any one of a plurality of cryostats without breaking the vacuum seal therearound when transferring from one cryostat or dewar to another. The detector is vacuum-jacketed and mechanically and thermally connected to an axially projecting conducting member, which member is received in a thermally conducting transition member contained in the cryostat. The transition member is thermally and mechanically coupled to the dewar and may include a fluid path completing a vacuum jacket in the dewar.
