Abstract
The present invention relates to an RF system (1) able to generate a voltage for accelerating charged particles in a synchrocyclotron, the RF system (1) including a resonant cavity (2) comprising a conducting enclosure (5) within which are placed a conducting pillar (3) of which a first end is linked to an accelerating electrode (4) able to accelerate the charged particles, a rotary variable capacitor (10) coupled between a second end opposite from the first end of the pillar (3) and the conducting enclosure (5), the said capacitor (10) comprising fixed electrodes (11) and a rotor (13) comprising mobile electrodes (12), the fixed electrodes (11) and the mobile electrodes (12) forming a variable capacitance able to vary a resonant frequency of the resonant cavity (2) in a cyclic manner over time, an exterior layer of the rotor (13) having a conductivity of greater than 20,000,000 S/m at 300 K. At least one part of the exterior surface (15) of the rotor (13) is a surface possessing a normal total emissivity of greater than 0.5 and less than 1, thereby allowing better cooling of the rotor and/or making it possible to dispense with a system for cooling the rotor by conduction and/or by…
