为满足兰州重离子加速器的实验要求,在14.5GHz高电荷态ECR离子源上做了一系列产生金属离子的实验,尝试了多种方法,包括炉子加热及MIVOC(Metallic Ion form Volatile Compounds)两种方法,其中,用炉子做的结果较理想.实验主要研究了铜、锌、镍多种电荷态离子的产生,具有代表性的是39euA的 Cu³⁺,30euA的Zn¹⁵⁺和29euA的Ni¹⁰⁺.分别给出了这三种金属离子产生的多电荷态束流峰谱图,以及实验的一些其它现象及结果,并对其进行了讨论与总结.

To satisfy the requirements of HIRFL (Heavy Ion Research Facility in Lanzhou),series of experiments have been done to produce metallic ion beams.By now,numerous methods,including oven heating and MIVOC (metallic ion from volatile compounds),have been tested.Experiments results show that oven heating is much better than MIVOC.In most of our researches,emphasis was put upon the ion production of copper,zinc,nickel of different charge states.Among the obtained ion beams,39eμA Cu¹²⁺,30eμA Zn¹⁵⁺,29eμA Ni¹⁰⁺ are the very representative ones.This paper presents the spectrums of the production of these three kinds of metallic ions as well as some phenomena and analysis on the oven heating experiment.
