Abstract

Abstract: The development of low resistivity material to increase the rate capability of Resistive Plate Chambers (RPCs) has been attracting more and more attention recently. This paper presents a new type of such a material. The new material is based on polyimide doped with carbon. The electrical volume resistivity of this material could be controlled using different percentages of the doping carbon. The standard thickness of polyimide carbon films is around 40 μ m which does not allow to use it as such to build the RPC electrodes. To overcome this, we developed a new stress method to make the gap between two polyimide carbon films. In this paper we will introduce the new detector material, the new type of RPC and the cosmic bench test results. In the future, if the polyimide is widely used in RPCs, the electrical properties changed by high energy particles should be well-studied.
