Dedicated machine time of about 10 weeks has been devoted to the high beam current experiment by using an electron beam of the TRISTAN Accumulation Ring (AR). In the experiment, we investigated performance of prototypes of RF cavity systems and a bunch-by-bunch feedback system which will be used in the KEKB. We found that the RF cavity systems work very well at the beam current more than 500mA. The bunch feedback system was very effective to suppress the instability. We also made an experiment
