[en] Two new beam diagnostics have been designed and are in operation at GANIL: - To measure very small beam currents without intercepting the beam, transformers have been developed by using source pulsation. - As the accelerated orbits in the second main cyclotron are overlapping one another, we cannot count the number of turns by a classical moving probe. Therefore we compute the cross-correlation function of the beam signals detected on inductive probes at the input and the output of the cyclotron. Thence the right number of beam turns can be calculated
