Comprehensive spectroscopic data for Yb atoms were experimentally collected, the optimum photoionization scheme was reasoned from the data, and the effect of laser characteristics on isotope selectivity was analyzed. The detailed designs for a 15W copper vapor laser and a 5W tunable laser were completed. The oscillator, the air-cooled laser plasma tube, the high voltage pulse generator, the buffer gas supplier, the automatic controller for the CVL system, and the SLM (single longitudinal mode) oscillator for the tunable laser system have been constructed. A vaccum chamber and an atomic beam generator for the high density ion separator system were designed and constructed. The computer simulation code for ion extraction was also developed. (Author).
