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. 621 - Accelerator Research and Development (POF4-621) G:(DE-HGF)POF4-621 POF4-621 POF IV 0 Dataset connected to DataCite Accelerator Physics Other 03 Transverse Profile and Emittance Monitors Other theory no experiment theory work (theory) EXP:(DE-Ds200)theory-20200803 EXP:(DE-Ds200)no_experiment-20200803 EXP:(DE-Ds200)no_experiment-20200803 0 Ady, Marton 1 Castro Sequeiro, Cristina 2 Churchman, Ashley 3 Forck, Peter P:(DE-Ds200)OR0310 4 gsi Mazzoni, Stefano 5 Sameed, Muhammed 6 Schneider, Gerhard 7 Sidorowski, Krystian 8 Stringer, Oliver 9 Udrea, Serban P:(DE-Ds200)OR1313 10 gsi Veness, Raymond 11 Welsch, Carsten 12 Zhang, Hao 13 Forck, Peter 14 Editor Wawrzyniak, Adriana 0000-0003-1807-3817 15 Editor Schaa, Volker R.
