IceCube-Gen2 Surface Array: Science Case and Plans

IceCube-Gen2 will be a next-generation extension of the IceCube Neutrino Observatory at the South Pole. In addition to a deep Optical Array and a Radio Array for PeV neutrino astronomy, IceCube-Gen2 will feature a Surface Array to enhance the neutrino science and to provide additional cosmic-ray science. The IceCube-Gen2 Surface Array will consist of elevated scintillation panels and radio antennas above the Optical Array and will detect cosmic-ray air showers in the PeV to EeV energy range. Compared to IceCube, the measurement accuracy at the surface will be enhanced due to the combination of radio and particle detection, and the aperture for surface-deep coincident events will be increased by about a factor of 30. This contribution will present the science case of the IceCube-Gen2 Surface Array and discuss the planned design recently published in the Technical Design Report: https://icecube-gen2.wisc.edu/science/publications/tdr/
