Abstract:
A variable rotating capacitor or RotCo 5 that can be connected via a transmission line 3 to the dee 2 of a synchrocyclotron 1 so as to adjust a resonant frequency of the synchrocyclotron as a function of time and which comprises a cylindrical rotor 10 and a cylindrical stator 20 that are coaxial with the Z axis. The rotor comprises a plurality of circumferentially-distributed rotor electrodes 11 extending parallel to its rotation axis Z. The stator comprises a plurality of circumferentially-distributed stator electrodes 21 extending parallel to the rotation axis Z. Each stator electrode 21 consists of a single metal plate and all said plates are distributed over one and the same stator circumference 25. 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.
