Description

Deep beneath the Canadian Shield, within the confines of the SNOLAB underground laboratory situated at the Vale-Creighton mine southwest of Sudbury, Ontario, lies the SNO+ experiment. This experiment, the successor to the SNO experiment, aims to observe neutrino-less double beta decay. SNO+ has been operational as a liquid scintillator neutrino detector since 2022. Specific hardware had been designed to maintain the strict radiological background mitigation criteria of the experiment. Prior to the recent assembly of this equipment the existing backgrounds, integrated over several month periods, were used to obtain the sets of decay events required to evaluate the detector’s behaviour. The completion of the deployment hardware has enabled the collection of a statistically significant calibration dataset spanning multiple deployments, totalling an aggregate of 16 days.

Throughout these deployments, the position response and accuracy of the deployment system were evaluated, providing feedback to the hardware development. The excellent accuracy of these systems; better than the detector resolution; will be presented. In addition the detector backgrounds and radon levels were also monitored throughout the deployment procedures, successfully maintaining the cleanliness goals of the experiment. This presentation will summarize all of the measurements conducted during the deployment period and provide prospects for forthcoming analyses based on these deployments.
