Abstract

The radiation environment in and near high gradient RF cavities is very important for the instrumentation of the MUCOOL experiment, since large fluxes of X rays and dark current electrons can interfere with the operation of the muon detectors. We have measured the X ray and dark current spectra from a single cell, 1.3 GHz, and are beginning to make more extensive measurements of a multicelled 805 MHz cavity. The results are consistent with electron field emission, bremsstrahlung and photon absorption/scattering. We discuss ways of minimizing this background and the scaling of these results to other cavities
