Abstract

In this R&D, an innovative method for producing thin high-pressure laminate (HPL) electrodes for resistive plate chambers (RPC) for future high-energy experiments is introduced. Instead of using thick phenolic HPL (2-mm thick Bakelite), which has been used for conventional RPC triggers, the RPC electrodes in the present study are constructed by bonding 500 {\mu}m-thick melamine-based HPL to a graphite-coated polycarbonate plate. A double-gap RPC prototype to demostrate the present technology has been constructed and tested for cosmic muons. Furthermore, the uniform detector characteristrics shown in the test result allows us to explore the present technology in future high-energy experiments.
