| contents | The reliability of large-area Resistive Plate Chambers (RPCs) operated under High-Luminosity Large Hadron Collider (HL-LHC) conditions is governed by the long-term stability and radiation tolerance of screen-printed graphite/phenoxy coatings on high-pressure-laminate (HPL) electrodes. This work presents a comprehensive, end-to-end qualification of such coatings that integrates industrial process control and metrology with controlled humidity/temperature campaigns, extended high-voltage stress testing to decade-scale charge levels, and representative neutron and gamma irradiation at CERN facilities. The results establish reproducible industrial coating production, stable performance under sustained operation and irradiation, and practical acceptance criteria with operating and monitoring guidelines. The study provides a transferable quality-assurance framework for graphite-based resistive coatings on HPL electrodes, enabling reproducible production and reliable RPC performance for the HL-LHC upgrades and for future high-rate collider experiments. |
