Six-gap resistive plate chambers for high-rate muon triggers

This paper reports the development of oiled multi-gap RPCs for use as high-rate triggers in high-energy physics experiments. The current R&D aims to improve the detector performance of RPCs in high pseudorapidity, ηη, in a CMS experiment of the LHC. In this study, six-gap prototype RPCs made from 1-mm thick high pressure laminated (HPL) resistive plates were designed and built. The detector characteristics of the prototype RPCs obtained from a series of tests with cosmic muons and gamma rays are discussed.
