ABSTRACT:
An object of the present invention is to provide a cooled NMR probe including an antenna coil and capable of decreasing an operation temperature of the antenna coil by effectively cooling the antenna coil, thereby increasing detection sensitivity of an NMR signal. To attain this, a probe head according to the present invention includes a coil support member which supports the antenna coil, and a cooling member arranged around at least a portion of the coil support member, the cooling member providing a cooling space between the cooling member and the coil support member, the cooling space allowing a refrigerant to circulate therethrough. The cooling member is coupled to the coil support member such that the refrigerant flowing in the cooling space directly contacts an outer peripheral surface of the coil support member.
