The design and mass production on Resistive Plate Chambers for the BESIII experiment

A new type of the phenolic paper laminate is used as the resistive electrodes of BESIII RPC. The surface smoothness of these laminates is comparable to that of the bakelite plates with linseed oil treating. A technique to adjust the bulk resistivity of the laminates within the range of 109–1013 Ω cm is developed. Nowadays, about 1000 bare chambers (1200 m2) have been produced and used for BESIII MUON, and the rejection rate is only 1.5%. In this paper, we will discuss the mass production and quality control procedures of these RPCs.
