Abstract
A low temperature probe having a coil used in an NMR apparatus includes an opposed heat exchanger cooling a cooling medium, and a cooling apparatus having a first cooling stage capable of cooling to no more than 10K and a second cooling stage capable of cooling to at least 10K in series cooling the cooling medium from the opposed heat exchanger. A probe portion has a first heat exchanging portion executing heat exchange between the cooling medium and the coil, a circulation structure which circulates the cooling medium into the opposed heat exchanger, a second heat exchanging portion executing heat exchange between the cooling medium and a heat radiation shield. The heat radiation shield has a heat capacity greater than the heat capacity of the cooling medium.
