A new semiautomatic system to produce carbon foils in the thickness range from 200 μg/cm2 to > 3 mg/cm2

Carbon foils or “strippers” play an essential role in the high yield production of multicharged ions used for heavy-ion accelerators. Therefore, large-scale production of thin films of carbon with very good homogeneity and high reproducibility is crucial. A semiautomatic system of carbon sublimation has been constructed in our laboratory. Most of the operations are controlled by a microprocessor to avoid manual imperfections. With this simple and efficient system, it is easy to get thin or thick carbon foils with good precision and high reproducibility.
