Extension Of The Lux-Zeplin Nr Background To 600 Phd, Jackson Codd
Macalester Journal of Physics and Astronomy
In June 2022, the LUX-ZEPLIN collaboration released its first results, with the
most precise measurements of any direct dark matter detector. The findings were
calculated using the expected spin-independent WIMP-nucleon interaction model,
which would result in small energies deposited in the detector. Therefore, the
background of non-dark interactions was calculated for events with S1 areas up to
80 phd (Aalbers et al. 2022). In order to increase the sensitivity to high energy
WIMP-nucleon interaction events, as predicted by other models, we extended the
non-dark NR background to events with S1 areas of up to 600 phd. We found a
large …

Supercdms: Energy Calibration Of A Ge Hv Particle Detector, Salamong Xiong, Vuk Mandic, Matthew Fritts, Nicholas Mast, Jacob Nelson
Macalester Journal of Physics and Astronomy
The goal of the SuperCDMS collaboration is to directly detect dark matter. Weakly Interacting Massive Particles (WIMPs) are potential candidates. To detect WIMPs, it is important to be able to predict how a Ge/Si particle detector will respond to a dark matter signal. In particular, it is necessary to calibrate the recoil energy measured by these detectors. This paper presents evidence for dark matter, a description of the detector operation, and procedures used to analyze measured data from a SuperCDMS-HV Ge particle detector using Am-241 and a PuBe neutron source. Due to high event rate, criteria were developed to remove …
