Design, Construction and Test Results of a Warm Iron HTS Quadrupole for the Facility for Rare Isotope Beams

The first quadrupole in the fragment separator region of the proposed Facility for Rare Isotope Beams would be subjected to extremely high radiation and heat loads ($\sim$15 kW in the magnet and 5 $\hbox{kW/m}^{3}$ in the coil). As a critical part of this proposal, a radiation resistant quadrupole made with first generation High Temperature Superconductor (HTS) has been built and tested. This paper summarizes design, construction and test results of this magnet that has been designed to operate at $\sim$30 K to remove this heat economically. Of particular interest are the simulated energy deposition experiments that demonstrate the stable operation of this HTS magnet in the presence of these unprecedented loads. The next quadrupole will use second generation HTS and is expected to operate at 50 K or above for even more efficient energy removal.
