Construction and Testing of Novel Designs of Resistive Plate Chambers

Resistive Plate Chambers (RPCs) continue to be one of the crucial components of the muon systems in current and future collider experiments, as well as the (semi-)digital hadron calorimeter developed by the CALICE Collaboration. A number of challenges are associated with RPC technology, including issues like loss of particle detection efficiency under high particle flux conditions and limitations associated with conventional RPC gases. To provide solutions to these problems, we have developed new RPC designs with: low resistivity glasses; a single resistive plate; a single resistive plate and a special anode plate coated with a material with high secondary electron emission efficiency. We have successfully demonstrated the feasibility of several designs and are currently in the process of testing the remaining ones to provide supporting evidence. Particularly, the newly developed functional RPCs are investigated in detail to assess the range of possible future implementations. This report focuses on outlining the assembly process for different RPC designs and presenting their performance results from both laboratory tests and beam tests. Additionally, we discuss our forthcoming testing strategies, encompassing extended performance assessments for the recently developed RPCs, investigations into chambers with minimal gas flow, and explorations into the viability of larger chambers.
