摘要： PURPOSE:To detect a quenching phenomenon beforehand by a method wherein a sound detecting element is attached to a superconductive magnet and the case, in which the detecting signal does not exist for longer than a pre-determined period while an applied current is being increased, is detected. CONSTITUTION:A sound generating element 21 for generating dummy sound signal is attached to an electrode part or a main part of a superconductive magnet 1. The sound signal generating element 21 is driven by periodical pulses from a pulser 20 and transfers a sound signal to a sound detecting element 2 through the magnet 1. The sound signal, given from the generating circuit 21 by the detecting element 2 is detected by a circuit 10 and compared with a threshold value by a comparing circuit 22 and converted into a pulse signal. When generating interval of these pulse signals becomes longer than a pre-determined period while a current applied to the superconductive magnet 1 is being increased, an AND circuit 24 produces an output and a quenching phenomenon is detected. When the quenching phenomenon is generated, a current breaking circuit 5 disconnects a source 6 from the magnet 1.

摘要： PURPOSE:To bend the end part of the curved side while preventing the collapse of a coiled conductor layer, by inserting a wedge between a dipole coil and a surface plate, and bending the end part of the coil. CONSTITUTION:A thin plate 7 to be deformed together with an unit coil 1a is put on a surface plate 5, and the coil 1a is put on the plate 7. Next, a load P1 is applied on the coil 1a after putting a convex press die 6b on the coil 1a to keep the coil 1a in a loaded state. Next, wedges 8a, 8b are inserted between the plate 7 and the plate 5 from both ends of the coil 1a, and loads P2 are applied to push the wedges 8a, 8b inward. Therefore, the coil 1a is bent along the surface of the die 6b. Further, the loads are not locally concentrated into one part and never cause the collapse of the coil layer because both ends of the coil 1a are deformed along the plate 7 and the wedges 8a, 8b.
摘要翻译：目的：通过在偶极线圈和表面板之间插入楔形物并弯曲线圈的端部部分来弯曲弯曲侧端部，同时防止线圈导体层的塌陷。构成：将与单元线圈1a一起变形的薄板7放在表面板5上，将线圈1a放在板7上。接下来，在将凸起压入后将负载P1施加到线圈1a上线圈1a上的芯片6b将线圈1a保持在负载状态。接下来，将楔8a，8b从线圈1a的两端插入板7和板5之间，并且施加负载P2以将楔8a，8b向内推。因此，线圈1a沿着模具6b的表面弯曲。此外，由于线圈1a的两端沿着板7和楔形8a，8b而变形，所以负载不会局部集中在一个部分中，并且不会引起线圈层的塌陷。

The spacer 4C is contacted merely with the pancake coils through the resin impregnated thin-sheet materials 11. Accordingly, the compressive strength of the spacer 4C is increased, and the spacer in which slackness is not generated even through cooling can be obtained.

摘要： PURPOSE:To prevent a creep voltage drop enen when water dew-condenses on the surface of a varnish layer by coating the outer surface of an insulating rubber hose flowing in or discharging a refrigerant with the varnish layer. CONSTITUTION:The whole circumference between both end flanges of the rubber section 5a and outer surface 5b of the insulating rubber hose 5 is coated with the varnish layer 7. According to such constitution, moisture dew-condenses on the surface 7a of the layer 7 due to temperature difference between the inside and outside of the hose 5 and the moisture of the outside air when operation, but moisture due to the dew condensation is interrupted by the layer 7, and does not reach the outer surface 5b of the rubber section having an impurity functioning as an ion current source. Consequently, a creep voltage does not drop due to the dew condensation, and the pipe for cooling the coil adopting the hose 5 has high reliability.
