abstract = {The first direct detection of neutrinos at the LHC not only
marks the beginning of a novel collider neutrino program at
CERN but also motivates considering additional neutrino
detectors to fully exploit the associated physics potential.
As the existing forward neutrino detectors are located
underground, it is interesting to investigate the
feasibility and physics potential of neutrino experiments
located at the surface-level. A topographic desk study is
performed to identify all points at which the LHC’s
neutrino beams exit the earth. The closest location lies
about 9 km east of the CMS interaction point, at the bottom
of Lake Geneva. Several detectors to be placed at this
location are considered, including a water Cherenkov
detector and an emulsion detector. The detector designs are
outlined at a conceptual level, and projections for their
contribution to the LHC forward neutrino program and
searches for dark sector particles are presented. However,
the dilution of the neutrino flux over distance reduces the
neutrino yield significantly, necessitating large and coarse
detector designs. We identify the experimental challenges to
be overcome by future research, and conclude that at present
the physics potential of surface-level detectors is limited
in comparison to ones closer to the interaction point,
including the proposed Forward Physics Facility.},
