Abstract: | After a brief review of various diagnostics for vacuum ion sources measured data are presented for the particle distributions within the anode/cathode gap regions using passive spectroscopy, active laser interferometry, and resonant laser-induced fluorescence, while the extracted ion beams were observed by particle track detectors of both time-integrated and time-resolved types. Also measured were the prompt gamma-rays and the D-D neutrons when the beams hit the targets. The experimental arrangements of these diagnostics, together with some examples of the typical results obtained, are shown. It is discussed how various kinds of particles were distributed within the ion diodes, and how they were extracted from the source regions |
