The Central Solenoid (CS) of a fusion reactor is expected to IMS operated around 1ST, 5. 8K, at ramp rates of 0, 51 TVs. The present state of the art of the superconductor technology »Hows (lit fulfillment of . such requirements only by means of coils made of CableInConduit Nb3Sn conductors (CICC). In the RNEA Kroscati laboratory, the construction of a CICC NbjSn coil (1m o. d. , O. Oni bore) was completed in 1994, Its original destination was the high field DC test facility SULTAN. Since many characteristics of this coil make it representative of a CS, it was decided that it was higher priority to test it in transient field conditions. An adhnc facility was designed and set np in the tLNEA bYnscnti Laboratory. The tests performed can be divided into four categories: 1. Ramp Uate Littiitfltions; 2. AC loss measurement on Hit whole coil; 3, Current redistribution inside the conductor induced by fast ramps, 4. DC performance within the limits of the facility. Wcll known and validated computer codes (SARUMAN and GANDALF) have been used both to predict the behaviour of the coil and to interpret the results. In ttie paper the results of all the tests are reported. Their influence un the design of CICC coils is discussed. © 2000 IEEE.
