Cosmogenic Muon Measurements for CURIE's Low-Background Quantum Facility
ORAL
Abstract
m.w.e.) providing a ~700fold reduction relative to sea level is cosmogenic muon flux and complete annihilation of the primary cosmogenic hadronic and electromagnetic components. CURIE offers a testbed for the development of superconducting qubits and novel detector technologies, as well as for studying backgrounds relevant to rare-event searches, such as those for dark matter and neutrinoless double-beta decay. To characterize the cosmogenic muon flux at this site, we deployed a remotely controlled muon telescope, capable of measuring muon intensities in a given direction. Profiling the angular distribution of this flux will provide critical information on the cosmogenic backgrounds, a crucial step in commissioning the CURIE facility. We provide measurements made both at Colorado School of Mines and at the CURIE facility.
