ENERGY CALIBRATION OF A 5.5 MV VANDEGRAAFF ACCELERATOR USING A TIME-OF-FLIGHT TECHNIQUE

Energy calibration of the analysing magnet for the University of México 5.5 MV Van de Graaff accelerator has been carried out using a time-of-flight method. The pulsed and bunched beam produced by the accelerator was used to deduce the energy E of the beam particles from the transit time between a coaxial pickup and a charged particle detector separated by 1.5 m. The measured FWHM energy resolution of this system was about 20 keV. © 1990.
