The production of one of the parts in a particle detector, called the RF Foil, has been a very intensive process in the past. The design and production process, which had a trial and error character, led eventually to an RF Foil that met the most important requirement: a sufficient leak tightness value. Since these kinds of foils have to be produced in the future, it is desirable to shorten the development stage with a view to cost reduction. This research project investigates how this part can be optimized with respect to the radiation length. An important limiting factor within this optimization process is the leak tightness of the foil. The intended production method this research will investigate is superplastic forming (SPF). On the one hand, the goal is to use finite element calculations to predict the forming behavior. The leak tightness of the formed foil must also be predicted within these calculations. On the other hand, an optimization strategy is necessary to reduce the radiation length of the RF Foil while maintaining the leak tightness.
