Lifetime of charge stripping foils and transmission of heavy ions in 12UD-pelletron tandem accelerator

The lifetime of charge stripping foils produced by means of new arc-discharge method developed by Sugai was measured for the bombardment of 10 MeV Au ions. Transmission of Au ions through 12UD-pelletron tandem accelerator was also measured. The lifetime of tested charge stripping foils for 10-15 μg/cm2 thick and 3.8-5.0 μg/cm2 thick, respectively, demonstrated to be longer than that of usual arc-discharge method by more than 30 times and 20 times, meanwhile, the transmission of 3.8-5.0 μg/cm2 thick foils was about 4 times higher than that of 10-15 μg/cm2 thick foils.
