Abstract

Several proposed and approved accelerator projects will need to deal with magnetic elements operating in high-radiation environments. Previous projects at LANL and PSI have relied on resistive magnets, but these new projects require the higher capabilities of superconducting magnets. A superferric dipole has been constructed using radiation resistant materials to meet these needs. The dipole uses cold iron and coils wound with materials that have high tolerance to the expected flux of high-energy neutrons. Primary insulation was polyimid and the coils were potted with CTD-422, a cyanate ester. The magnet operated at slightly greater than the manufacture´s guaranteed short sample current. Quench characteristics were compared with calculations, indicating a relatively slow transverse propagation.
