文摘For the first time the physical properties of therapeutic carbon-ion beam supplied by the shallow-seated tumor therapy terminal at the Heavy Ion Research Facility in Lanzhou (HIRFL) are measured, where a significant reference is afforded for the shallow-seated tumor clinical trail. For 12C ion beam of 80. 55 MeV/ u delivered by the therapy terminal, the homogeneity of irradiation fields which has a diameter of 45 mm
