RPC production for fast muon trigger system for PHENIX

Presently, PHENIX is developing a fast muon trigger system based on resistive plate chambers (RPCs) combined with an upgrade of the existing muon tracker electronics. The primary goal of the PHENIX muon trigger system upgrade is to study the flavor dependent quark and antiquark polarizations in the proton by tagging high momentum muons from the W decay. For the production of the PHENIX muon trigger RPCs, we take advantage of the existing facilities and expertise that have been accumulated by the Korea Detector Laboratory (KODEL), Korea University, during the development of the forward muon trigger system for the CMS collaboration at the LHC. In this paper, we first summarize the physics motivation of the fast muon trigger system for PHENIX, and introduce the procedure for gas gap production and quality assurance plan.
