Description
Internal calibration sources used in SNO+ have been deployed last year (2025). In order to maintain the quality of the liquid scintillator in the SNO+ Acrylic Vessel (AV), calibration sources must be cleaned and confirmed to be at the desired cleanliness level for SNO+ scintillator. A bespoke Source Cleaning Vessel (SCV) was developed for this task, recirculating a closed-loop volume of SNO+ liquid scintillator. Cleanliness quality for the sources was determined using Liquid Particle Counting (LPC) and UV-Vis spectroscopy of the cleaning scintillator.
