Description
Deep underground low-background laboratories are critical infrastructure for dark matter experiments and rare event physics searches. With real-estate in short supply, we are establishing a new underground laboratory in Tichinio, Switzerland. With 4000 meters water equivalent overburden, the Bedretto Lab has amongst the lowest cosmic ray fluxes in the world. The radiogenic backgrounds from muons, gamma-rays, neutrons, and radon have all been characterized. Seismic and electromagnetic noise were extensively studied. The Bedretto Lab will be amongst the lowest noise and lowest background laboratories in the world. We propose three immediate use cases: technology demonstrators for the upcoming XLZD experiment, hosting cryogenic low-mass dark matter experiments, and installation of an atomic interferometer sensitive to both gravitational waves as well as wave-like dark matter.
