Descripción
The SuperCDMS SNOLAB experiment is an upcoming direct detection dark matter experiment using semiconductor crystal detectors operated at cryogenic temperatures. The experiment is located 2 km underground in the Creighton mine at Sudbury, Canada. With low background from cosmic sources, SNOLAB is ideal for rare event searches. The experiment uses 24 detectors, made of silicon and germanium, comprising of two detector types: one with phonon channels that is operated at high voltage (∼100 V), utilizing the Neganov-Trofimov-Luke (NTL) effect to amplify the phonon signal and achieve a low energy threshold, and another with phonon and charge sensors that enables effective background rejection. The experiment will probe low-mass WIMPs, dark photon absorption, and Axion-Like Particles. The commissioning phase is underway later this year, and science data-taking is expected to begin by mid-2026. This talk gives an overview of the experiment, its science goals, and a status update of the experiment at SNOLAB.
