Query: IceCube-Gen2: A Vision for the Future of Neutrino Astronomy in
  Antarctica   The recent observation by the IceCube neutrino observatory of an
astrophysical flux of neutrinos represents the "first light" in the nascent
field of neutrino astronomy. The observed diffuse neutrino flux seems to
suggest a much larger level of hadronic activity in the non-thermal universe
than previously thought and suggests a rich discovery potential for a larger
neutrino observatory. This document presents a vision for an substantial
expansion of the current IceCube detector, IceCube-Gen2, including the aim of
instrumenting a $10\,\mathrm{km}^3$ volume of clear glacial ice at the South
Pole to deliver substantial increases in the astrophysical neutrino sample for
all flavors. A detector of this size would have a rich physics program with the
goal to resolve the sources of these astrophysical neutrinos, discover GZK
neutrinos, and be a leading observatory in future multi-messenger astronomy
programs.
