Abstract
A variable rotating capacitor or RotCothat can be connected via a transmission lineto the deeof a synchrocyclotronso as to adjust a resonant frequency of the synchrocyclotron as a function of time and which comprises a cylindrical rotorand a cylindrical statorthat are coaxial with the Z axis. The rotor comprises a plurality of circumferentially-distributed rotor electrodesextending parallel to its rotation axis Z. The stator comprises a plurality of circumferentially-distributed stator electrodesextending parallel to the rotation axis Z. Each stator electrodeconsists of a single metal plate and all said plates are distributed over one and the same stator circumference. This makes it possible for the RF currents in the electrodes to be better distributed and thus reduces the local overheating. The present invention also relates to a synchrocyclotron comprising such a RotCo.
