摘要： PURPOSE:To avoid the damage of a superconductive coil by a method wherein a cooling equipment is composed of a cold box for generating cryogen, a liquid He storag and a cryogenic container in which a superconductive coil is stored and prescribed valves are provided between the storage and the container. CONSTITUTION:High purity He gas, compressed by a compressor 1, is introduced into a cold box 2 and a part of it is turned into liquid He by expansion turbines 4a and 4b. The produced liquid He is led into a He storage 10 through a conveyor tube 9a to be stored as liquid He 11. Then, a part of the liquid He 11 is led into a cryogenic container 18, in which a superconductive coil 19 is stored, through a conveyer tube 12 to cool the coil 19. In this configuration, a manual valve 13b is provided to the conveyer tube 12 and the storage 10 and the container 18 are connected by a connecting tube in which manual valves 14a and 14b for recycling are connected in parallel. With this constitution, when an abnormal voltage detector 22 operates, the valve 14b is opened and at the same time the valve 13b is closed.

摘要： PURPOSE:To reduce temperature rise in a tank of cryostat and to enable complete exhaust of refrigerant of a precooler for superconducting magnet by a method wherein a heater and a temperature measuring element are provided at the tank bottom part of cryostat, and the heater is controlled monitoring existence of the refrigerant by the temperature measuring element. CONSTITUTION:A superconducting magnet 2 is accomodated in the cryostat 1, and a pipe 3 is arranged as to open to the tank bottom part and a pipe 4 as to open to the upper part of the tank. The electric heater 6 is fixed to the tank bottom part, and is connected to a feed control circuit through a lead wire 7, and the temperature measuring part 9 of a thermoelectric couple 8 is fixed to the heater 6. A cold junction 10 of the thermoelectric couple 8 is equipped in a small heat insulating tank 11 as to be submerged in the refrigerant 5 for precooling, and a voltmeter 12 for temperature measurement is connected as to measure the temperature difference between the temperature measuring part 9 and the cold junction 10. Accordingly although the refrigerant 5 for precooling is poured in the tank when precooling is to be performed, and the refrigerant 5 is exhausted after the superconducting magnet is cooled, but when the refrigerant 5 is remained in the tank, because waste of refrigerant is generated, so that the remained refrigerant can be exhausted by making a current to be connected and disconnected from the heater monitoring deflection of the indicator of a voltmeter.
摘要翻译：目的：为了降低低温恒温箱的温度升高，并通过一种方法使超导磁体的预冷器的制冷剂完全排出，其中加热器和温度测量元件设置在低温恒温器的罐底部，并且加热器被控制通过温度测量元件监测制冷剂的存在。构成：超导磁体2被容纳在低温恒温器1中，并且配管3设置成向罐底部开口，而管4打开到罐的上部。电加热器6固定到罐底部，并通过引线7连接到馈电控制电路，热电偶8的温度测量部分9固定在加热器6上。将热电偶8安装在小型绝热罐11中，以浸没在用于预冷却的制冷剂5中，并且连接用于温度测量的电压计12，以测量温度测量部分9和冷接点10之间的温差。因此，虽然在进行预冷却时将用于预冷却的制冷剂5注入罐中，并且在超导磁体被冷却之后制冷剂5被排出，但是当制冷剂5保留在罐中时，由于产生制冷剂的浪费，使得通过使电流与电压表的指示器的加热器监视偏转相连接和断开而使剩余的制冷剂可以被排出。

摘要： PURPOSE:To prevent the temperature rise of a superconductive coil in which a cooling passage is formed at a spool by molding the coil with synthetic resin by enclosing the outer periphery of the cooling passage with a thermal conductor. CONSTITUTION:A superconductive coil 1 is integrally impregnated with synthetic resin such as epoxy resin or the like and is fixed together with a spool 2 surrounding the outer periphery of the coil 1, and a cooling passage 3 is formed at the spool 2. This spool 2 and the passage 3 are formed of high strength member such as stainless steel or the like. A thermal conductor 6 such as an aluminum plate or a copper plate or the like is intimately secured by a welding or a bolt clamping to the outer periphery of the spool 2 and the passage 3. The heat generated from the coil 1 is transmitted to a freezing medium flowing through the passage 3 provided at the spool 2 to cool the coil 1. The heat and electromagnetic wave introduced from the exterior to the coil 1 are absorbed by the thermal conductor 6 and are transmitted to the freezing medium flowing through the passage 3 in the form of the heat to perform cooling.
