Contribution

This paper presents the design, science goals, and ongoing development efforts of the IceCube-Gen2 facility, expanding the observatory's sensitivity and energy range.

Findings

IceCube-Gen2 will increase observed neutrino rate by an order of magnitude.

It will detect five times fainter neutrino sources.

The extension will measure astrophysical neutrinos at much higher energies.

Abstract

The IceCube Neutrino Observatory opened the window on neutrino astronomy by discovering high-energy astrophysical neutrinos in 2013 and identifying the first compelling astrophysical neutrino source, the blazar TXS0506+056, in 2017. In this talk, we will discuss the science reach and ongoing development of the IceCube-Gen2 facility---a planned extension to IceCube. IceCube-Gen2 will increase the rate of observed cosmic neutrinos by an order of magnitude, be able to detect five-times fainter neutrino sources, and extend the measurement of astrophysical neutrinos several orders of magnitude higher in energy. We will discuss the envisioned design of the instrument, which will include an enlarged in-ice optical array, a surface array for the study of cosmic-rays, and a shallow radio array to detect ultra-high energy (>100 PeV) neutrinos. we will also highlight ongoing efforts to develop and test new instrumentation for IceCube-Gen2.
