The design of faraday cup for C-ADS injector I

Abstract In this paper, a Faraday cup is designed for the “China Accelerator Driven Sub-Critical System” (C-ADS) Injector I. This Faraday cup is used to absorb the high-energy proton beam, preventing damage to C-ADS Injector I from waste particles. The SRIM program is used to simulate the energy deposition when the proton beam is absorbed by the target material. Thermal analysis is conducted using Ansys software to optimize the material selection for the target and the structure of the Faraday cup. The shape of the target is also discussed in detail. Additionally, a water-cooling structure is presented to further improve the heat dissipation of the Faraday cup. Results indicate that graphite is an ideal material for the target, and pure copper is used as the structural material.
