摘要： 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.

摘要： There is provided a nuclear magnetic resonance probe in which the loss caused by a high frequency cable between a probe coil and a preamplifier is reduced and the sensitivity of an NMR signal is improved. A changeover switch for NMR probe is divided into a switch part including switch elements and a filter part for filtering a switch control signal and an RF transmission signal. The switch part is disposed in a probe body inserted in a magnet of the probe. The filter part is disposed near a measurement apparatus located outside the probe. As for the switch part, a section structure of thickness and width is reduced in conformity with a narrow and slender shape of the probe body. The length of a high frequency cable between the probe coil and the preamplifier is shortened remarkably, and consequently the loss can be reduced.
