In cooperation with the university hospital Charité – Universitätsmedizin Berlin the Helmholtz-Zentrum Berlin (HZB) provides a proton beam used for radiation therapy of intraocular tumors. The protons are accelerated to 68 MeV by an isochronous cyclotron as the main accelerator. The human eye is a very small and complex organ with several critical structures which must be spared from irradiation as much as possible. Hence radiation therapy with protons is especially convenient due to their well-defined Bragg peak. At the HZB the distal fall off (the distance between 90% and 10% of the dose level) is less than 1 mm in water. Therefore it is crucial to measure the energy and maximum range of the beam with the corresponding high accuracy. A Multi-Leaf Faraday Cup (MLFC) allows a quick and precise range-measurement of proton beams. We present a MLFC which meets those special requirements of the eye tumor therapy. Results of range-measurements in different energy regions revealing the achievable submillimeter precession are shown; and examples for applications in radiation hardness testing are given.
