The domestic test of the Japanese LCT coil was carried out in 1982. During this test , the coil was charged up to the single coil's 100% state (10.22kA, 6.4T, 106MJ) four times and experienced no quenche. At the 100% charging state, coil stability was tested by using heaters installed in the conduc tor, A half turn length normal zone (about 5m) generated by heaters was spontenously disappeared in 2 second. This normalized zone included the highest magnetic field position. The transport current

... hich gives the stable limit is extraporated to be about 12.5kA at 8T by this test result. The dump test was carried out also from the 100% charging state. At that time, about 90% of the coil's stored energy was extracted by the dump resistor and the coil was not damaged.
