Abstract

The Compact Muon Solenoid (CMS) forward resistivity plate chambers (RPCs) at the high eta region must be operated in presence of a radiation-induced rate as high as 1 kHz/cm². It is still unknown if the RPCs coated with linseed oil can be operated under such a high-radiation environment over the lifetime of CMS. Non-oiled RPCs may be one of the options since phenolic or melamine-coated bakelite is chemically stabler than linseed oil. We have constructed oiled and non-oiled RPCs at the high eta region of CMS using phenolic bakelite and tested them in the Gamma Irradiation Facility at CERN. While both RPCs show the same characteristics in the efficiency and the strip multiplicity, the non-oiled RPC generates an intrinsic noise rate of 50 Hz/cm², compared to only 5 Hz/cm² for the oiled RPC, both at 10.0kV which is about 100 V above the 95% knee of the efficiency curve.

Funding Information:
We would like to thank the CMS RPC group, particularly the CMS RPC group at University of Bari. A. Colaleo and F. Loddo at University of Bari helped us set up the data acquisition system and the front-end electronics, respectively. Special thanks go to Prof. R. Santonico for sharing his expertise on RPC, especially for providing valuable information on linseed oil coating. We also wish to express our thanks to the accelerator division at CERN, and to the people responsible for the GIF. Finally, we like to acknowledge the support by the Ministry of Science and Technology, Republic of Korea, by the KISTEP under Grant no. M6-9701-00-0002, and by the KOSEF under Grant No. R01-2001-000-00015.
