Suppression of carbon buildup and lifetime improvement by heating carbon stripper foils

The foils treated by the newly developed present method could withstand the maximum and average total beam charges of 530 mC/cm2 and 340 mC/cm2, respectively, which are approximately 18 and 11 times larger than the values for the best commercially available foils and approximately 3 and 2 times greater than the values for the cluster foils that are not treated by this method.
