Background considerations for low rate SSG detector experiments

The low energy thresholds achieved with detectors made of superheated superconducting granules (SSG) encourage to use these devices for low rate measurements like WIMP search or coherent neutrino scattering experiments. Such applications need powerful rejection criteria for background events from electronic noise, cosmic and gamma radiation. In order to develop background rejection strategies, the origin of background sources and their interactions with SSG detectors need to be known. We present a discussion about electronic noise as well as background radiation together with their effects on the SSG detector counting rate. (orig.)
