中文摘要：

介绍了中国科学院近代物理研究所研制的一套用于低熔点靶材料的转靶系统。靶盘上用于实验且厚度0.4–0.6 mg/cm2的C/Pb/C夹心靶,在束斑为0.785 cm2、流强～1 eμA、能量为5.84 MeV/u的24Mg7＋束和流强～0.1 pμA、能量4.95 MeV/u的64Ni19＋束长时间照射下未损坏,照射总剂量约达1015。

英文摘要：

A rotating target wheel for targets of low melting point was designed at IMP.Isotopically enriched Pb targets of about 1.5 cm ？6.0 cm and of thicknesses of 0.4–0.6 mg/cm2,covered with thin C layers on both sides,were mounted on the wheel and irradiated by 5.84 MeV/u 24Mg7＋ ion beams of up to 1 e？A,and 4.95 MeV/u 0.1 p？A 64Ni19＋ ion beams on a beam spot of 0.785 cm2,with a total particle dose on the targets of about 1015.No damage to the targets was observed.
