LUX: WIMP search results, background monitoring and calibrating with tritium
Abstract - The Large Underground Xenon (LUX) experiment has recently placed the most stringent limit for the spin-independent WIMP-nucleon scattering cross-section. The WIMP search limit was aided by a novel internal tritium source resulting in an unprecedented calibration and understanding of the electronic recoil background. The LUX experiment also employed a gas analysis technique allowing for in situ monitoring of radioactive backgrounds and electronegative impurities dissolved in the xenon. This talk will begin with a report on the first WIMP limit from LUX, followed by a description of an in situ gas analysis program and the development, deployment, and exploitation of a tritium calibration source used to characterize the LUX detector.
