Electronics Development for the New Photo-Detectors (PDOM and D-Egg) for IceCube-Upgrade

Understand

The planned IceCube-Upgrade will enhance the capability of IceCube in the detection of GeV-scale neutrino physics and enable an improved measurement of the properties of the glacial ice.

• Three types of new optical sensors will be deployed during the Upgrade: PDOM, D-Egg, and mDOM.
• Since the design of the PDOM and D-Egg are very similar, the development of the front-end electronics for the two optical sensors has been merged.
• The photo-electron signals detected by the PMTs are digitized with high-speed ultra-low power ADCs and processed in an FPGA, before being sent to the data acquisition system located on the surface of the South-Pole glacier.
