• The ion extraction characteristics were investigated when a barium plasma was suddenly produced between alternately biased parallel plate electrodes by simultaneously illuminating a tuned dye laser and an excimer laser light. Time evolution of the ion density profile measured by means of laser-induced fluorescence indicated that the ions in the plasma are alternately extracted to both sides following voltage switching, and then, the plasma diffusion has little effect on the density change. As a result, the ion extraction time, which was measured by ion current detection, is reduced by about 0.71 times that for parallel plate electrodes when a constant voltage was applied. This curtailment rate can be deduced by applying the scaling relation established for constantly biased parallel plate electrodes.
