    • The invention relates to a method and device for measuring the location of a particle beam (10) present in packets in a linear accelerator comprising a hollow chamber structure (4) in which an electromagnetic wave oscillating at a base frequency (f0) is generated in order to accelerate the particles, wherein an electrical measurement signal (M) generated by the particle beam (10) by means of electromagnetic interaction with the measurement recorder (16) is recorded by at least one measurement recorder (16) disposed in the hollow chamber structure (4), said signal being a function of the distance between the measurement recorder (16) and the particle beam (10). According to the invention, the measurement signal (M) is analyzed in a frequency range different from the base frequency (f0) and higher natural frequencies of the hollow chamber structure (4), comprising a whole multiple of the base frequency (f0).
