Abstract

We report results of the experimental test of the High Temperature Superconductor based fast cycling prototype accelerator magnet capable to operate up to about 300 Tesla per second field ramping rate with some 0.5 T field in the magnet gap. The measured upper limit for the cryogenic cooling power required to support magnet conductor operation at high ramping rates indicates great potential for such types of magnets in rapid cycling synchrotrons for neutrino research or muon acceleration. The test magnet design, construction, and supporting cryogenic and power systems are briefly described. The magnet power test results are discussed in terms of a possible upgrade of this magnet design to 2 T field, a maximum feasible with superferric magnet.
