Description
このパルス管の低温端部付近の外側に部分的に蓄冷管を同心的に配置し、この蓄冷管と前記パルス管との間に、第1の断熱管を前記パルス管と前記蓄冷管とが重なる位置に配置するとともに、前記第1の断熱管よりも高温端側に、第2の断熱管を、前記第1の断熱管と直列に結合され、かつ、前記第1の断熱管と内部が連通するようにして配置し、かつ前記蓄冷管と前記第1の断熱管との間に蓄冷機能を有する金網で構成したメッシュパイプを収めるとともに、前記パルス管と前記蓄冷管とを両者の低温端側で連通させ、さらに、前記パルス管と前記第1の断熱管および前記第2の断熱管との間に真空層を設けるとともに、この真空層内の前記第1の断熱管と前記パルス管との間の前記第1の断熱管と第2の断熱管の結合部付近に限定して輻射熱遮断体を配置することにより、前記パルス管と前記蓄冷管とを熱的に絶縁したことを特徴とするのである。
