Reproducibility and simplification of the preparation procedure for carbon stripper foils by laser plasma ablation deposition

Carbon stripper foils prepared by laser plasma ablation deposition are so far the only ones which have a total random orientation of the nanocrystallites. This orientation is responsible for the long lifetimes under heavy ion bombardment. Accelerator users around the world are interested in this type of carbon stripper foils. Their strong interest is a guaranteed reproducibility of the foil quality, -thickness and -uniformity. In addition, a high reproducible yield with a low effort for floating, mounting and slackening is wanted. These problems are discussed and the status of their solution is described.
