The Element Selectivity And Laser Technique Of The Laser Ion Source Used For On-Line Isotope Separator

The necessity and possibility of improving the isotope separator on-line are analyzed. The principals of laser stepwise resonance ionization and laser ion source at ISOL are introduced. The element selectivity of the hot capillary type laser ion source and its influence factors are analyzed in detail. The lasers and laser technique used in the laser ion source are alse described. The laser ion source of the capillary type was tested by the experiments. Its result proved that the laser ion source has an opportunity element selectivity from 50 to 10000.
