摘要：
Measurements of the X-ray flux, electron flux and spectrum are presented with the aim of evaluating the usefulness of ionization sensitive single particle detectors in the immediate environment of an rf cavity. The measured fluxes are found to be roughly consistent with field emission of electrons followed by one generation of bremsstrahlung photon production, with absorption and scattering of the final photons and electrons in the cavity and vacuum chamber structure.
