Cosmic-Ray Physics in the PeV to EeV Energy Range with the IceCube-Gen2 Surface Array
No full textIceCube-Gen2 is a proposed neutrino observatory at the South Pole that will build on the success of IceCube and will also serve as a unique detector for cosmic-ray air showers.
Analogous to the IceTop surface array over IceCube’s deep optical detector, IceCube-Gen2 will also feature a surface array above an optical array deep in the ice. As improvement over IceTop, the IceCube-Gen2 surface array will be comprised of elevated detectors to avoid snow coverage, and will combine two types of detectors: scintillation panels that measure air-shower particles on ground and enable a low detection threshold, which is important to serve as a veto for selecting downgoing neutrino candidates; and radio antennas which increase the measurement accuracy for air showers by providing a calorimetric measurement of the electromagnetic shower component and its depth of maximum, Xmax. As another major advantage, the eight times larger surface area combined with a larger field of view will provide a 30-fold increase for the aperture of surface-deep coincident events. With these improvements in statistics and measurement accuracy, IceCube-Gen2 will thus make unique contributions to the particle physics and astrophysics of Galactic cosmic rays in the PeV to EeV energy range, including the search for PeV photon sources. This proceeding will summarize the technical design and science case enabled by the IceCube-Gen2 Surface Array

Science Potential and Technical Design of the IceCube-Gen2 Surface Array
Full text linkIceCube-Gen2, the next generation extension of the IceCube Neutrino Observatory at the South Pole, offers a unique scientific potential for cosmic-ray physics at PeV to EeV energies complementing the main science case of neutrino astronomy. The cosmic-ray science case will be enabled by a surface array on top of an extended optical array deep in the polar ice. The optical array measures TeV muons of air showers, and the surface array primarily measures the electromagnetic shower component and low-energy muons. The design of the surface array foresees scintillation panels providing a full-efficiency threshold for near-vertical proton showers of 0.5 PeV and radio antennas increasing the measurement accuracy for the electromagnetic shower component in the energy range of the Galactic-to-extragalactic transition. Compared to IceCube, the aperture for air showers measured in coincidence with the surface and optical arrays will increase by a factor of 30, due to the larger area and angular acceptance in zenith angle. The science potential includes both, the particle physics of air showers, such as prompt muons, and the astrophysics of the highest energy Galactic cosmic-rays, enabled by the higher sensitivity for the mass composition and anisotropy of cosmic rays, and by the search for PeV photons. This proceeding summarizes the science case and design of the surface array as presented in the recently released IceCube-Gen2 Technical Design Report: https://icecube-gen2.wisc.edu/science/publications/tdr
Towards IceCube-Gen2: Plans for the in-ice radio array
No full textBuilding on the success of IceCube at the South Pole, the next generation experiment IceCube- Gen2 is taking shape. Next to an extension of the optical array, further developing the optical detector learning for the IceCube-Upgrade currently in preparation, IceCube-Gen2 is planned to feature a large in-ice radio array targeting neutrinos beyond PeV energies. This radio array will build on heritage from many former and existing radio neutrino experiments. It will dominate the sensitivity of IceCube-Gen2 at EeV energies, improving at least an order of magnitude in sensitivity over existing arrays. IceCube-Gen2 will also feature a much enlarged surface array, including in-air radio antennas targeting air showers. This contribution will highlight the current status of IceCube-Gen2 with a focus on the in-ice radio array

Direction reconstruction for the in-ice radio array of IceCube-Gen2
No full textThe IceCube-Gen2 facility will extend the energy range of IceCube to ultra-high energies. The key component to detect neutrinos with energies above 10 PeV is a large array of in-ice radio detectors. In previous work, direction reconstruction algorithms using the forward-folding technique have been developed for both shallow ( m) and deep in-ice detectors, and have also been successfully used to reconstruct cosmic rays with ARIANNA. Here, we focus on the reconstruction algorithm for the deep in-ice detector, which was recently introduced in the context of the Radio Neutrino Observatory in Greenland (RNO-G). We discuss the performance-critical aspects of the algorithm, as well as recent and future improvements, and apply it to study the performance of a station of the IceCube-Gen2 in-ice radio array. We obtain the angular resolution, which turns out to be strongly asymmetric, and use this to optimize the configuration of a single station
IceCube-Gen2: the next-generation neutrino observatory for the South Pole
No full textThe IceCube Neutrino Observatory is a cubic-kilometer Cherenkov telescope buried in the icesheet at the South Pole that detects neutrinos of all flavors with energies from tens of GeV to sev-eral PeV. The instrument provided the first measurement of the flux of high-energy astrophysicalneutrinos, opening a new window to the non-thermal universe. Here we present design studiesfor IceCube-Gen2, the next-generation neutrino observatory for the South Pole. IceCube-Gen2will have an instrumented volume nearly 10 times greater than IceCube alone, substantially in-creasing sensitivity to high-energy neutrinos. On the surface, a large air shower detector willveto high-energy atmospheric muons and neutrinos from the southern hemisphere, enhancing thereach of astrophysical neutrino searches. In the ice, a number of new optical module designscurrently being evaluated will allow for substantially increased photosensitive area per unit cost.We show how these different sensor designs affect the instrument’s ability to resolve the sourcesof astrophysical neutrinos
