PURPOSE: To obtain a weak field measuring device which can endure against tension/stress due to different temperature contraction while supporting an inserter stably in a Dewar vessel thereof and in which maintenance is facilitated by suppressing leakage of heat. CONSTITUTION: A sensor 12, a cross-connection module 6, a connection element 4, a neck plug 3 and a top plate 2 are interconnected through a connector so that they can be removed easily. Consequently, the inserter can be removed easily from the Dewar vessel and abutted resiliently against the bottom part and the wall of the Dewar vessel. The neck plug 3, i.e. a self-suppoting module comprising a radiation shield and cable wiring, introduces cold helium gas being fed out. |
