摘要： The invention provides nuclear magnetic resonance equipment realizing improved sensitivity of a probe for receiving a free induction decay (FID) signal in nuclear magnetic resonance (NMR) spectroscopy in a high frequency band of 600 MHz or higher. By manufacturing a solenoid coil of a higher filling factor by using a superconductor of extremely low resistance to high frequency current, sensitivity is increased. A superconducting thin film made of magnesium diboride (MgB2) formed on a donut plate-type substrate is disposed so that the film surface becomes parallel with the uniform magnetic field. The object is realized by a probe made by a solenoid coil formed by connecting a plurality of coil parts by capacitive coupling via a normal metal lead.

摘要： A double-tubular third transfer tube is provided in the transfer tube storage conduit, and a first transfer tube, second transfer tube and fourth transfer tube are installed in its interior. Further, pressure control valves are arranged in the portion of normal temperature, thereby reducing the amount of heat intrusion and the coolant temperature. This arrangement cryogenically cools down the irradiation coil and reception coil, without damaging the compressor, and ensures a low-temperature probe to be manufactured.
