An aperture-collimated nuclear microprobe was set up in the early 1980’s at Fudan University. Since then, techniques and applications of nuclear microprobes in China have been developed and progressed for more than thirty years. There are seven accelerator-based nuclear microprobe facilities available in China now. They are able to provide micro beams with ion energies from 1 MeV to 1 GeV. These microprobes have been utilized to obtain spatial information or radiation effect in solids and biological samples. In air and in vacuum microprobes were constructed. Techniques of ion beam analysis methods, single ion hit were also developed for these applications. This paper describes their technological performance. It also presents the latest progress of applications on ICF (Inertial confinement fusion) target, CdZnTe detector, information safety and so on.
