  • Patent number: 9351391
    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.
    Type: Grant
    Filed: November 15, 2012

    Assignee: Ion Beam Applications
    Inventor: Patrick Verbruggen
  • Patent number: 9271385
    Abstract: A magnet structure for use in a circular ion accelerator, such as e.g. a synchrocyclotron comprises a cold-mass structure including superconducting magnetic coils (20, 25), at least one dry cryocooler unit (10, 11, 12, 13) coupled with the cold-mass structure for cooling the latter and a magnetic yoke structure (30) with a return yoke (35) configured radially around said coils (20, 25). The return yoke (35) comprises an opening in which said dry cryocooler unit (10, 11, 12, 13) is received so as to be in thermal contact with said cold-mass structure.
