SuperCDMS Detector R{\&}D: SNOLAB and Beyond

SuperCDMS (Cryogenic Dark Matter Search) is an experiment designed to directly detect dark matter particles in the form of WIMPs (Weakly Interacting Massive Particles). Germanium and silicon detectors, cooled to \textless 30mK, are instrumented to simultaneously measure phonon and ionization energy deposited by incident particles, allowing event-by-event discrimination, to identify and study possible WIMP interactions. Using phonon amplification via the Neganov-Luke effect, recent studies utilizing a modified version of these detectors (called CDMSLite) have demonstrated the energy resolution necessary to search for WIMPs of mass $\sim$ 1 GeV/c$^{2}$. A recent design, inspired by these studies, has led to a world record ionization resolution of 8eV.
