摘要

The ARGO-YBJ detector is located at Yang Ba Jing (P.R. China), at 4300 m a.s.l. and atmospheric depth of606 g/cm2. The Resistive Plate Chambers (RPCs) of the ARGO-YBJ detector are operated with a three-component gasmixture (C2H2F4/Ar/iC4H10=75/15/10) in streamer mode at a constant applied voltage of 7200 V, at room temperatureand atmospheric pressure. However, at constant applied voltage the gas gain is a function of the gas density, dependingspecifically on the temperature and the atmospheric pressure. By using a test stack of RPCs placed nearby the mainARGO carpet, the effective voltage in the RPC gas gap is controlled by exploiting the monitoring of the environmentalparameters provided by the ARGO detector control system. The goal of this study is to develop a reliable procedure forthe stabilization of the gas gain in the RPCs of the ARGO detector.
