High energy heavy ion microbeam irradiation facility at IMP

A high energy heavy ion microbeam irradiation facility was designed and installed in the Institute of Modern Physics (IMP) of Chinese Academy of Sciences (CAS). It can deliver well-focused ions into the targets at exact locations. With the advantage of allowing vertical irradiation as well as focusing ions from Carbon to Uranium with high energies in a broad energy range (7 MeV/u to 100 MeV/u for Carbon ions), this setup is able to deliver a preset number of ions into pre-selected target positions. Material specimens in vacuum and living cells in air can also be irradiated by this facility. Detailed description of this microbeam facility as well as its beam optics is presented in this paper. Some preliminary test results are also given.
