Abstract :
A 30-kA, 70-cm-bore pulse coil was designed and fabricated. The charge-up test, the manual dump test and the heater test were carried out. The PUP was charged up to 30 kA at 5.8 T without any appearance of a normal zone. The manual dump from 30 kA at 9 T/s was carried out without any damage. In the heater test, the innermost one-turn normalcy at 30 kA and 5 T recovered spontaneously to the superconducting state in 10 s. These results indicate that the electromagnetic and the thermal performances are excellent.
