Descripción
IceCube-Gen2 is a future large-scale extension to the IceCube Neutrino Observatory, a kilometer-scale neutrino detector at the geographic South Pole. The IceCube data acquisition system (DAQ) architecture, while running stably with over 99% uptime, will be re-optimized for IceCube-Gen2 to solve design challenges with power consumption, communications bandwidth, and cable specifications, while also integrating new types of instrumentation such as the cosmic ray and radio neutrino detection components. In particular, we describe how distribution of the photomultiplier tube signal digitization and pre-trigger storage can reduce power and bandwidth requirements. Changes to IceCube's custom communications protocol can also relax crosstalk requirements on the copper cabling. We report on the status of these optimizations in the prototype Gen2 digital optical module design for the upcoming IceCube Upgrade.
