H. Muto et al., BEHAVIOR OF CARBON STRIPPER FOILS PREPARED BY A MIXED ION-BEAM SPUTTERING METHOD, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 103(2), 1995, pp. 249-251
Carbon stripper foils have been prepared by a mixed ion beam sputterin
g method and the lifetime measured by using 3.2 MeV Ne+ ions. Foils pr
epared by the mixed ion beam sputtering method have lifetimes ranging
from 10 to 125 times longer than those produced by thermal evaporation
method. Changes in foil thickness with increasing fluence were examin
ed. The lifetime and sputtering ratio of the carbon foils were found t
o be strongly dependent on thickness.
