Abstract
The lifetime of carbon stripper foils when bombarded whith 4.8 MeV A ++ ions in a hydrocarbon-free vacuum environment has been investigated. The lifetime of the foils is limited not by thickening but by shrinkage and rupture, and can be improved by a factor of 3 by irradiating at a temperature of 600 °C. Thinner foils (nominally half thickness) produced on a cellulose backing had a shorter life, but since the transmitted beam is greater, they show an improvement of 30 %. Further improvements in foil lifetime can only be achieved by reduction of the shrinkage rate, or by improvements to the resistance of the foils to shrinkageKeywords
