  The safety re-examination of existing GANIL facilities requires the implementation of a safety system which makes a control of beam intensities sent in the experimental rooms possible. The aim is to demonstrate that beam intensities are below the authorized limits. The required characteristics should enable the measurement, by a non-interceptive method, of beam intensities from 5 nA to 5μA with a maximum uncertainty of 5%, independently of the frequency and the beam energy. After a comparative study, two types of high frequency diagnostics were selected, the capacitive peak-up and the Fast current transformer. This paper presents the signal simulations from diagnostics with different beam energies, the uncertainty calculations and the results of the first tests with beam.
