Na-22 source study in the SuperCDMS experiment — •Fatema Khozema Thasrawala, Alexander Zaytsev, Hanno Meyer zu Theenhausen, Lea Burmeister, Matthew Wilson, and Belina Von Krosigk — University of Hamburg

The SuperCDMS experiment focuses on searching for WIMPs and light dark matter particles. SuperCDMS detectors are designed with the primary function of detecting the minute crystal lattice vibrations (phonons) and ionization (charge) generated within the crystal by low-mass dark matter particles and elastic collisions between crystal nuclei or electrons. An applied bias voltage across the detector amplifies event signals and allows for low-energy collisions to be measured. An analysis is underway to investigate the effects a radioactive source has on the events observed. One of the sources studied was sodium-22 with an activity of 4.6uCi which was placed near the detector. We present preliminary results about this study performed using the radioactive source at various bias voltages applied to the detector.
