Description
Future collider experiments impose stringent requirements on muon detector technologies, demanding large-area coverage at low cost per channel, high detection efficiency, time resolution on the order of a few hundred picoseconds, and long-term operational stability. Resistive Plate Chambers (RPCs) remain strong candidates for next-generation muon systems, and ongoing R&D is pursuing thin-gap glass RPC designs that aim to meet these performance targets.
This work reports on the characterization of thin-gap glass RPC prototypes, including double-gap and double bi-gap layouts with 500 μm gas gaps, tested with cosmic rays and under beam conditions. Time resolution measurements demonstrate that these prototypes achieve values of approximately 200 ps, establishing thin-gap glass RPCs as competitive candidates for future collider muon systems. Operational working points, signal charge spectra, and detection efficiency are reported alongside performance evaluations using different gas mixtures. Improved spatial resolution through charge-centroid analysis is also discussed. Taken together, these results establish the viability of thin-glass RPCs as a high-performance, robust, and scalable detector technology.
