Supporting Stations: McMurdo Station, South Pole Station
Leveraging the experience of the IceCube collaboration and the currently operating infrastructure of the IceCube Neutrino Observatory, a five-year project is proposed to advance the state of the art in multimessenger astronomy with neutrinos and improve on the ability of IceCube to make a unique measurement of the unitarity of the PMNS (Pontecorvo-Maki-Nakagawa-Sakata) matrix. This award, the IceCube Gen2 Phase 1 extension, will fund the deployment of seven additional strings of photon sensors at the bottom center of IceCube. The new strings will use multiple photomultiplier tube (PMT) Digital Optical Modules (mDOMs) that provide better directionality and more than double the photocathode area per module, at lower cost per unit area, than traditional IceCube DOMs.
Field Season Overview
The team's mission while in McMurdo is to gain access to the Enhanced Hot Water Drill (EHWD) generators and Power Distribution Module (PDM) to perform repairs, start-up, and testing. Their activities at Pole will focus on better defining the status of the Gen1 EHWD that will be refurbished for the upgrade project. Specific activities include: (1) flagging the perimeter of the construction zone for the proposed 2022-23 season upgrade; (2) performing a ground penetrating radar survey of the construction zone; (3) performing a detailed review of all dedicated EHWD mobile drill structures; (4) testing high pressure pumps using station power; and (5) preparing equipment for retrograde.
