A CS module is composed of the 52 layers pancake coils. The 26 helium flowing paths are in a one module. The refrigerator supplies helium at 4.4 K to each flowing paths in nominal operation. In case of a quench, the refrigerator stops helium supply in order to shut out large heat load from the quenched magnet. The temperature distribution of the quenched CS will be smoothed by a heat conduction between each pancake coils while helium is stopped. Helium will be supplied again when the magnet pressure become low enough. The temperature distribution changes are calculated by using SuperMagnet.
