LONG-LIVED CARBON STRIPPER FOILS FOR INTENSE HEAVY-ION BEAMS

Carbon foils with the thickness of 40µg/cm2 were produced as charge strippers for intense heavy-ion beams. The lifetimes of the carbon foils were measured with 32 keV/nucleon 136Xe9+ beam. The lifetimes more than 100 times longer than the foils on the market with the same thickness were attained by choosing the graphite materials
