Dark rates induced by radioactive decays in optical modules for neutrino telescopes
In the framework of a planned upgrade of the IceCube Neutrino Observatory and a next-generation neutrino telescope at the South Pole, new optical modules are being developed which are expected to significantly increase the detector sensitivity. As the deep ice at the South Pole has no intrinsic opti...
