Abstract: 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.
