Abstract: This paper describes the ion beam irradiation facility built up at the 4 MV electrostatic accelerator of Shanghai Institute of Applied Physics (SINAP), CAS for simulating neutron damage to thorium molten salt reactor (TMSR) material studies. The system mainly consists of a beam line containing the magnetic scanning device and the beam monitoring device, and the high temperature high vacuum chamber. H+, He+, Ar+ ions(<4 MeV, 2 A) from the accelerator are used for ion beam irradiation. The range of irradiation temperature is from the liquid nitrogen temperature to 950 ℃. The maximum irradiation field is equal to 30 mm30 mm. Beam energy degrade with rotating aluminum foils is installed in the chamber, so that the uniformity damage can be obtained within a certain range of the target materials. The preliminary ion irradiation experiments showed that this facility is suitable for exploring radiation effects on the refractory metals as well as other potential TMSR materials.
