摘要： PROBLEM TO BE SOLVED: To reduce the danger of an excessive floating magnetic field very much when quench takes place in a magnet device which contains an interval bridged by at least a protective element provided with a dipole moment which is not negligible. SOLUTION: A magnetic device is equipped with a certain number (not zero) of area windings and an additional closed current path (C3) inductively coupled (not zero) with an interval Ai. By this setup, the excessive floating magnetic field of the magnet device can be restrained by selecting the dimensional design of the additional current path (C3) when a magnet coil system (M) is quenched.

摘要： PROBLEM TO BE SOLVED: To provide a magnet device with an additional magnetic field generation coil system, wherein a current is supplied from an external power supply for generating magnetic field inside a working volume which is not substantially 0, and its design method. SOLUTION: The magnet device generates a magnetic field in the direction of a z axis in a working volume disposed around z=0. It has a superconducting magnet coil system M with at least one energizing coil, an additional magnetic filed generating coil D where a current is supplied from an external power supply and which generates a magnetic field which is not substantially 0 in a working volume, and optionally another superconducting closed current path (P1,..., Pn). In the device, a magnetic filed in the direction of a z axis is generated in operation by a current induced thereby in an operation volume, and a magnetic field of the additional magnetic field generation coil D does not exceed 0.1 Tesla. In the magnet device, it is possible to improve the device to maximize effective magnetic field efficiency of the additional magnetic field generation coil system D to the conventional superconducting magnet coil by taking diamagnetic characteristics of a superconductor inside the superconducting magnet coil M into consideration.

摘要： PROBLEM TO BE SOLVED: To provide an NMR measurement device with a temperature control element for a sample vial.SOLUTION: An NMR measurement device includes a temperature control element for a sample vial 1 where a temperature control fluid 8 brought under the temperature control of a heater 12 flows at its periphery. Further, the NMR measurement device is provided with a temperature sensor 9 such that a measurement head projects into a measurement space 14 spatially closely to the sample vial 1. A supply wire for the temperature sensor 9 is arranged in another space different from the measurement space 14. The temperature sensor 9 including the supply wire is surrounded with the sensor tube 15 at a radius distance, and a partial flow of the temperature control fluid 8 enters a free space 17 as a temperature control flow 16 from the measurement space 14 through a sensor flow entrance 26 and exits from the sensor tube 15 through a sensor flow exit 18 at an end on the opposite side from the sensor tube 15. Consequently, a temperature crossover and a temperature difference (ΔTp) between the temperature sensor 9 and sample vial 1 are both minimized.

摘要： PROBLEM TO BE SOLVED: To provide a coil assembly for nuclear magnetic resonance.SOLUTION: The coil assembly includes a main coil 13, a shielding coil 14, and at least one correction coil 41, and the correction coil functions for forming such a magnetic field gradient that eddy current characteristics are as good as possible. The main coil 13 and the shielding coil 14 are electrically connected in series to the correction coil 41. Therefore, deviation of a residual magnetic field from a desired design, which is caused by manufacturing tolerances, is corrected by the correction coil so that a durable eddy current can be suppressed. Thus, the waiting time required for extinction to achieve a predetermined field homogeneity after a gradient pulse is reduced, or for example, deviation from a desired field can be minimized in imaging applications.
