Description

The upgrade of the High-Luminosity LHC (HL-LHC) will boost the instantaneous luminosity to 5-7 × 10^34 cm⁻²s⁻¹, increasing particle fluxes in the forward region of the CMS detector. The high particle flux can damage electronics and induce spurious signals. This study focuses on the GE1/1 triple-GEM detector’s sensitivity to both neutral and charged background particles, performed using FLUKA and Geant4 simulations. FLUKA provides a comprehensive description of the radiation field around the GE1/1 chambers across a broad energy spectrum. Geant4 delivers complementary insight into the detector response based on realistic geometry, materials, and interaction processes. The results show how the detector’s sensitivity changes with particle energy and incident angle, and how different configurations affect its performance. The talk also includes comparisons with CMS Run 3 data, providing valuable guidance for optimizing GEM operation under HL-LHC conditions. Moreover, this approach can be extended to other forward detectors like ME0 during the HL-LHC era.
