Abstract

A sample tube (50) is arranged in a sample temperature adjusting pipe, and a temperature adjustment gas is supplied. A vacuum vessel (28) is formed with the sample temperature adjusting pipe (24) and an outer wall body (26), and a detection coil (52) to be placed in a cooling state are arranged in the vacuum vessel. A sealed section between the sample temperature adjusting pipe and the outer wall body is sealed by a sealing structure. The sealing structure includes a high-vacuum O-ring (60) and a low-temperature O-ring (58). The high-vacuum O-ring has characteristics for sealing the sealed section in a regular temperature region. The regular temperature region is a temperature region excluding a low temperature region, and the low temperature region is a temperature region including a lower limit in a possible temperature adjustment range of the temperature adjustment gas. The low-temperature O-ring has characteristics for sealing the sealed section in the low temperature region.
