NMR detection module

摘要

An NMR (nuclear magnetic resonance) detection module (such as an NMR probe) mounted in a vacuum vessel is offered. This module permits a transmit/receive coil to be cooled efficiently and to be placed closer to a sample container. The NMR detection module includes a core module (detection module) (54) consisting of a refrigerant block (118) and a transmit/receive coil formed on the inner surface of a detection hole (130). A sleeve (cylindrical partition wall) (122) forming a part of the vacuum vessel is inserted in the detection hole (130). A sample tube (56) is inserted in the sleeve (122). The refrigerant block (118) is connected to a heat exchanger via a support member (82). Since it is not necessary to form a bobbin inside the transmit/receive coil, the distance between the coil and the sample can be set small. Because the coil is entirely surrounded by the refrigerant block, the coil is cooled efficiently.
