Description
The development of low resistivity material to increase the rate capability of the RPC has been attracting more and more attention recently. We present here a new type of such a material. The new material is based on the polyimide doped with carbon. The electrical volume resistivity of this material could be controlled using different percentage of the doping carbon. The standard thickness of polyimide carbon films is around 40 um 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 lager area of RPC will be made and the different characteristics will also be tested.
