摘要： An object of the present invention is to solve the bending of an NMR probe and a room temperature shim coil so that they can be positioned easily. In the NMR spectrometer including split-pair magnets and a cross bore, a high rigidity straight pipe to which an NMR probe and a room temperature shim coil are attached so as to make an integral object, is provided. The outer diameter of the straight pipe is smaller than the inner diameter of a horizontal bore into which the room temperature shim coil and the probe are inserted. After the room temperature shim coil and the NMR probe are attached to the straight pipe by bolts, respectively, the integral object is inserted into the horizontal bore (a room temperature space) of the NMR spectrometer. The room temperature shim coil and the probe may be attached to different straight pipes.

摘要： In NMR system, for preventing a temperature gradient which causes a decrease in S/N ratio from being created in a sample area while suppressing deterioration in homogeneity of a magnetic field, a thermal conductor having high thermal conductivity is disposed in a room-temperature shim coil. The thermal conductor is provided as a coil bobbin, the temperature of the thermal conductor being controlled by a temperature controller using a heat exchanger. Temperature control gas, which is adjusted to a temperature equal to that of the room-temperature shim coil, is fed from the downside of a sample tube, and it is possible to suppress a temperature gradient from being created in a sample area. According to the present invention, since the temperature distribution can be made to be uniform so as to avoid creating a temperature gradient in the sample area while suppressing deterioration of homogeneity in the magnetic field, the NMR spectrum is sharpened so as to improve the S/N ratio.

摘要： In a pressurized superfluid helium cryostat, a first flow rate control valve and a preliminary cooler are installed between a liquid helium inlet at a bottom portion of a 4.2K liquid helium bath and a J-T valve which is a second flow rate control valve. The preliminary cooler is cooled by depressurization by a vacuum pump. The liquid taken in from the 4.2K liquid helium bath is cooled to a temperature of the preliminary cooler by J-T expansion in the first flow rate control valve, and stored in the preliminary cooler. The liquid helium in the preliminary cooler can be cooled below 2.2K, and further subjected to J-T expansion in the J-T valve. By installation of the preliminary cooler, the efficiency of the superfluid cooler can be increased as compared to a conventional type.

摘要： An antenna coil is formed by a wire rod obtained by combining and integrating two or more kinds of materials having different magnetisms. The wire rod has a circular or polygonal cross sectional shape. The two or more kinds of materials having different magnetisms are combined so that the magnetisms of the combined materials are set off. The wire rod is wound around a bobbin so as to have a solenoid shape. Desirably, the low-magnetic wire rod is placed in an atmosphere whose temperature has been reduced to 10° K or less or superconductive filaments are formed in the outermost layer. Preferably, a part of the superconductive filaments are exposed.
