New submissions to the thesis/dissertation collections are added automatically as they are received from the Graduate School. Currently, the Graduate School deposits all theses and dissertations from a given semester after the official graduation date. This means that there may be up to a 4 month delay in the appearance of a give thesis/dissertation in DRUM

    Signal Corrections and Calibrations in the LUX Dark Matter Detector
    (2016) Knoche, Richard; Hall, Carter; Physics; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    The Large Underground Xenon (LUX) Detector has recently finished a 332-day exposure and placed world-leading limits on the spin-independent WIMP-nucleon scattering cross section. In this work, we discuss the basic techniques to produce signal corrections, energy scale calibrations, and recoil band calibrations in a dark matter detector. We discuss a nonuniform electric field that was present during LUX's 332-day exposure, and detail how such a field complicates these calibration techniques. Finally, we expand on the techniques presented earlier, such that they account for all of the complication introduced by the nonuniform electric field, and allow a limit to be produced from the data.
