Characterization of the analog front-end of the mDOM for the IceCube Upgrade at different temperatures — •Judith Schneider — Friedrich-Alexander-Universität Erlangen-Nürnberg, ECAP

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. One of such concepts is the multi-PMT Digital Optical Module (mDOM) which features 24 three-inch PMTs inside a pressure vessel resulting in a homogeneous directional sensitivity. An interacting neutrino creates secondary particles producing Cherenkov light which is detected by the PMTs. The PMT signal is processed by an analog front-end (AFE). All 24 channels are digitized separately with a 125 MSPS ADC. We present characterization measurements of the AFE of the mDOM for the IceCube Upgrade at different temperatures including -40°C as a proof of concept.
