    摘要： A variable rotating capacitor or RotCo (5) that is adapted to 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 0 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..

    摘要： A capacitor is provided, which allows a user to readily change or adjust its capacitance value. The capacitor includes a dielectric film, which includes first and second conductor layers disposed on opposite surfaces thereof, and which is wound into a rod shape. First and second electrodes are led out from the first and second conductor layers, respectively. At least one of the first and second conductor layers includes an area-changeable conductor pattern, which is disposed (e.g., exposed) on an outer circumference side of the capacitor wound into the rod shape to receive physical treatment (e.g., cutting, connecting) from outside to thereby change the size of a conductor area of the at least one of the first and second conductor layers. Thus, the physical treatment changes the conductor area of the conductor layers, to thereby selectively set or adjust the capacitance value of the capacitor.
