      abstract     = {In a gas jet monitor, a supersonic gas curtain is injected
                      into the beam pipe and interacts with the charged particle
                      beam. The monitor exploits fluorescence induced by beam-gas
                      interactions, thus providing a minimally invasive transverse
                      profile measurement. Such a monitor is being developed as
                      part of the High Luminosity LHC upgrade at CERN. As a
                      preliminary study, the fluorescence cross section of
                      relevant gases must be measured for protons at 450 GeV and
                      6.8 TeV (i.e. the LHC injection and flat top energies). In
                      these measurements, neon, or alternatively nitrogen gas,
                      will be injected into the LHC vacuum pipe by a regulated gas
                      valve to create an extended pressure bump. This work
                      presents the optical detection system that was installed in
                      2022 in the LHC to measure luminescence cross-section and
                      horizontal beam profile. Preliminary measurements of
                      background light and first signals are presented in this
                      paper.},
