A superconducting cyclotron based proton therapy facility is being developed for/at Huazhong University of Science and Technology (HUST). The proton beam is extracted by means of electrostatic deflectors followed by a series of magnetic channels. This paper introduces the design of an electrostatic deflector, including the structure optimization and the material selections. In order to minimize the risk of destruction caused by the proton beam loss, fluid-solid-heat coupling analysis for the deflector has been conducted by applying computational fluid dynamics (CFD) on ANSYS 16.0 software. The maximum temperatures of the septum in various cases of cooling water speed, septum thickness and material have been investigated respectively. The result based on thermal analysis will give us a valuable reference to choose a suitable configuration for the deflector.
