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 configuration of an NMR apparatus is provided. In the NMR apparatus, a magnetic field space of higher uniformity is generated by split superconducting magnets. At the same time, it is provided with a cryo probe excellent in cooling capability and sensitivity between two superconducting solenoid coils constructed in very close proximity to each other. For this purpose, a probe coil provided between the two superconducting solenoid coils is so constructed that the following is implemented: a certain distance is ensured between a substrate with a coil formed thereon and another, and the substrates and spacer substrates for cooling are alternately laminated. The spacer substrates are cooled by a cold head of sapphire. When the probe coil is inserted in the same direction as a sample tube (direction perpendicular to the static magnetic field), the spacer substrates cannot be coupled directly by the cold head of sapphire. Therefore, they are cooled through a fixed substrate for thermal conduction of sapphire coupled with the cold head.

摘要： An NMR system that enables multiplex resonance measurement includes a superconductivity reception coil, a transmission coil, and four electric current loops. The NMR system also includes an additional coil in which directions of currents that flow in an inner loop and an outer loop are opposite to each other. The additional coil and the transmission coil are arranged such that a direction of a high frequency magnetic field that is developed in the center of the additional coil when electricity is fed to the additional coil is substantially identical with a direction of a high frequency magnetic field that is developed in the center of the transmission coil when electricity is fed to the transmission coil. The electric current loop of the transmission coil is arranged substantially in the middle of the inner loop and the outer loop of the additional coil in which directions of electric currents that flow in the inner loop and the outer loop are opposite to each other.
