摘要
We measured the beam intensity of highly charged heavy ions (O, Ar and Kr ions) as a function of the minimum strength of mirror magnetic field (B-min) of the RIKEN liquid-He-free super conducting electron-cyclotron resonance ion source. In this experiment, we found that the optimum value of B-min exists to maximize the beam intensity of highly charged heavy ions and the value was almost the same (similar to0.49 T) for various charge state heavy ions.
