AbstraktAbstract

IceCube Upgrade, starting in the Antarctic summer season 2025/2026, will enhance the sensitivity of the current IceCube in the GeV range and improve understanding of the ice properties. Around 700 new modules will be deployed deep in the ice along seven strings, spaced 3 m vertically within a horizontal region of 100 m. IceCube Upgrade mainly consists of two types of Cherenkov photon detectors, ∼ 280 Dual optical sensors in an Ellipsoid Glass for Gen2 (D-Eggs) and ∼ 400 multi-PMT Digital Optical Modules (mDOMs). Here, we present the status of mDOM production and acceptance testing for mass-produced mDOMs. The majority of the modules have already been produced, and all 128 modules on the first 2 strings have been successfully shipped to the South Pole after multiple steps of testing. Each mDOM contains 24 photomultipliers nearly isotropically distributed on the surface to achieve uniform photon sensitivity, making the integration and testing complicated. To reduce the amount of testing time, we have developed parallelized and automated software.
