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.

The phase 1 of the SPIRAL2 facility is under construction at the GANIL (Caen, France). The accelerator including a RFQ and a superconducting linac will product deuteron, proton and heavy ion beams in a wide range of intensities and energies (beam power range: a few 100W to 200kW). The measurements of the beam intensities are ensured by several AC and DC Current Transformers (ACCT/DCCT). These measurements are required for the accelerator tuning and the beam controls for safety requests during the daily operation. The uncertainty has to be taken into account to determine the threshold value. This paper presents the measuring chain description of ACCT/DCCT, the signal processing by integration and the uncertainty studies.
