The goal of this full-scale experiment was to tune the cyclotron at very low-intensity (102 – 103 pps). A special low-intensity probe for phase measurements was built and tested in the GANIL SSC2 cyclotron. It is based on a fast plastic scintillator and mounted on a radial probe. Using this detector the phase extension and the central phase of the beam were measured and the cyclotron isochronism was accurately tuned.
