摘要：

The absolute energy of the beam from the CV28 cyclotron in the KFA Julich has been determined by measuring the spatial separation between neighbouring bunches in the transport system. The method uses two capacitive pickups inserted in the straight line in such a way that the downstream one can be moved longitudinally along the beam axis. The measurement is performed completely on-line, a personal computer controls the position of the probe and evaluates the signal produced by the HF detector electronics. Applying a moderate distance of about 2.5 m between the pickups, an accuracy of better than 3 X 10(-3) has been achieved with different beams in the intensity range of 1-20 mu A.
