| Abstract: | The feasibility of a heavy ion beam with a tandem acceleration system for plasma potential measurement has been examined. A plasma-sputter-type ion source which produces an Au- beam with an energy width as small as 6 eV and a reasonably small emittance of π mm-mrad (MeV)½, can be used for this purpose. Suitable target gas thickness for a charge exchange is estimated to be less than 1015 atom/cm2 at the 3 MV terminal voltage |
