At the last VLVnT-conference in the talk “NEVOD as a test facility for future neutrino telescopes” presented by A.A. Petrukhin the methods for testing of optical modules inside the volume of the Cherenkov water detector NEVOD have been discussed. It was assumed that in 2020 the new optical module mDOM of the IceCube-Upgrade will be calibrated in this way. However, the covid-19 pandemic did not allow to realize this plan.
So, these methods have been tested on quasispherical optical module QSM-6M, in which PMTs FEU-200 were replaced by PMTs of Hamamatsu R877. The spatial lattice of the detector NEVOD and deployed outside of the water tank calibration telescope system and coordinate-tracking detector DECOR allow calibrating the response of OM with respect to the Cherenkov light from single muons, muon bundles and cascades with known trajectories. Technique and results of calibration optical modules QSM-6M are presented at this talk.
