    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.

    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.
