Gamma background in the XENON-10 detector

The XENON-10 detector is the research and development phase leading up to a larger detector, using liquid xenon to directly search for dark matter (it is assumed that dark matter is composed of Weakly Interacting Massive Particles, or WIMP's).~ Due to the sensitivity needed for such a detector, it is vital to have a strong understanding of the background events that will be seen.~ Initial screening of many of the components comprising the XENON-10 detector has been completed using a High Purity Germanium detector.~ Results from said screening will be presented and the impact these results have on Monte Carlo simulations of the XENON-10 detector will be shown.
