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 signal line is drawn from a generally middle point of the antenna coil, and a capacitance-variable capacitors are connected at both sides of the antenna coil. This structure realizes a circuit in which a series resonance circuit composed of an antenna coil and a capacitor and an another series resonance circuit composed of an another antenna coil and an another capacitor are connected in parallel to each other across the generally middle point of the antenna coil to which the signal line is connected. Through the control of the resonance frequencies of the series resonance circuits, the parallel resonance frequency of the whole antenna is tuned to a desired frequency, and the resonance characteristic in which the impedance is matched to a specific value, e.g., 50 Ω, can be achieved.
