Abstract: Electron linear accelerators are used to generate X-ray radiation for the treatment of tumors. Efficient irradiation of tumors can only be guaranteed if the electron beam is guided accurately and so the required dose profile is applied. The deviation from the ideal path of the electron beam is measured by means of so-called beam position monitors and then corrected by magnets. According to the invention the deviation of the electron beam is measured in a drift tube of the linear accelerator, the wave to be decoupled having a frequency range that corresponds to a multiple of the basic frequency of the acceleration field. Coupling probes, a mixer-based receiving concept with high dynamics and sensitivity, a method for evaluating the measuring signals and a calibration method for calibrating out non-linearities are specified. Disruptive influences through the acceleration field are minimized by the measurement method according to the invention and the frequency range to be evaluated.
