Description
The Low Background Group at SNOLAB supports rare-event physics experiments through ultra-low background measurements and material assays in one of the deepest underground laboratories in the world. The group provides capabilities in high-purity germanium gamma-ray spectroscopy, ICP-MS, alpha screening, radon measurements, and neutron measurements to support experiments in dark matter, neutrino physics, and other low-background experiments. As next-generation rare-event physics experiments continue to increase in size and sensitivity, improvements in low-background assay techniques and measurement sensitivities to meet the increasing radiopurity requirements are necessary. This presentation will describe SNOLAB's low-background measurement facilities and recent developments and measurements which will help to increase the sensitivity of our low background detectors and improve detection limits. The intrinsic background measurement program of the SNOLAB underground will be discussed and plans for expanded low-background measurement capabilities and collaborative opportunities will be described.
