The high energy irradiation terminal for bio-medical research (CSRm-ET1) at the Heavy Ion Research Facility in Lanzhou (HIRFL) is a horizontal beam line for irradiation with charged particles and equipped with both passive and active beam delivery systems. All types of ions from proton to uranium can be provided in this terminal and the size of irradiation field with uniformity better than 90% is up to 20cm×20cm. Researches on heavy ion radiobiological effect, heavy ion therapeutic technique and relevant mechanism, hazard and evaluation of space heavy ions, and heavy ion radiation effect can be conducted in the CSRm-ET1 terminal. Therefore, the CSRm-ET1 terminal at HIRFL is a multi-functional experiment platform for interdisciplinary research across various fields, including biology, medicine, materials, and beyond.
