The Helmholtz-Zentrum Berlin (HZB) provides together with the University Hospital Charité in Berlin a treatment of eye tumors with a proton beam. The 68 MeV proton beam is delivered by an isochronous cyclotron as main accelerator. In tumor irradiation treatment the positioning of the radiation field is very important. In eye tumor treatment it is even more important, due to the small and sensitive structures in the eye. Hence, due to the well defined Bragg peak, a proton beam is a good choice to achieve rather small fields of dose delivery. Again, due to the small structures in the eye, one needs to know the proton beam energy and the proton beam range with a high accuracy. One possible solution for a quick and high precision measurement of the range of such proton beams is a Multi-Leaf Faraday Cup (MLFC). This work has the task to develop such a MLFC concerning the special requirements of the eye tumor therapy. In this presentation an overview of the progress of this work will be given, regarding the MLFC principles and issues such as the first technical realization.
