Stripping Efficiency and Lifetime of Carbon Foils
  Charge-exchange injection by means of carbon foils is a widely used method in accelerators. This paper discusses two critical issues concerning the use of carbon foils: efficiency and lifetime. An energy scaling of stripping efficiency was suggested and compared with measurements. Several factors that determine the foil lifetime - energy deposition, heating, stress and buckling - were studied by using the simulation codes MARS and ANSYS.
