ABSTRACT:
The invention provides a low temperature probe having a high sensitivity by reducing a heat intrusion into a receive coil. A heat making an intrusion into a coil is suppressed by inserting a heat radiation shield in which a temperature is controlled at about 100 K to a portion between an outer container of a probe and a coil portion. A heat radiation shield bore sleeve is provided in a heat radiation bore, is connected to the heat radiation shield, and is cooled by a second heat exchanger. Further, the coil portion is cooled by a first heat exchanger. In preparation for a contraction at a time of being cooled, the outer container, the heat radiation shield and the coil portion are connected by using a fixing portion, and a heat relieving mechanism or a contraction relieving mechanism is provided in a root side (an opposite side to the fixing portion) of the heat radiation shield and the coil portion. The fixing portion is formed in a shape and made of a material having a small heat intrusion amount and having a small heat contraction.
