Microbeam Technology and Application Group

Brief Introduction

High-energy heavy ions with energy of MeV to GeV are widely present in space environments, radiotherapy, and heavy ion accelerator laboratories. Exposure to high-energy heavy ions can cause severe single-event effects, biological radiation effects, and material modification. Microbeam technology that focuses high-energy heavy ions to micron/nanoscale provides precise irradiation, micro/nano fabrication, and material analysis techniques with micrometer resolution at the single-transistor, single-cell, or single-ion levels. Microbeam technology not only helps to understand the interaction between high-energy heavy ions and matter, but is also a unique tool for exploring the application of heavy ion irradiation effect, especially the study of space single-event effect, functional nanomaterial fabrication, and biological effect of heavy ion radiation.

The Group of Microbeam Technology and Applications focuses on ion beam physics and technology. The HIRFL microbeam facility operated by the group realizes the high-energy heavy ion microbeam technology with at 100 MeV/u energy level for the first time in the world, and is the single-ion microbeam facility of the highest energy in the world. Based on this facility, multidisciplinary interdisciplinary experimental research and national laboratory user services such as single-ion hit, single-event effect analysis, irradiation effect and material analysis, online live cell imaging, micro-irradiation of live animals and materials, and information security attack can be carried out.
