By using a novel camera setup, the range of the proton beam is measured optically. The setup consists of a phantom, a luminescent layer inside and a CMOS camera. By measuring the emission of the luminescent layer, the Bragg peak and the range of the proton beam can be visualized for different energies. In contrast to a water bath, the camera system offers much shorter measurement times. A dedicated LabVIEW code offers various evaluation possibilities: the Bragg curve and the lateral beam profile are generated and displayed. The system is sensitive to energy differences of less than 400 keV. The results were obtained with a beam intensity of less than 10 pA/cm² homogenous proton beam in front of the degrader. The measurement is done in real time and provides live feedback on changes such as beam energy and beam size. The results of the camera are presented and compared to water bath measurement.
