摘要： A synchrocyclotron for extracting charged particles accelerated to an extraction energy includes a magnetic unit comprising N valley sectors and N hill sectors, and configured for creating z-component of a main magnetic characterized by a radial tune of the successive orbits. The synchrocyclotron includes a first instability coil unit and a second instability coil unit configured for creating a field bump of amplitude increasing radially. The amplitude of the field bump may be varied to reach the value of the offset amplitude at the average instability onset radius. The offset amplitude may be the minimal amplitude of the field bump at the average instability onset radius required for sufficiently offsetting the center of the orbit of average instability onset radius to generate a resonance instability to extract the beam of charged particle at the average instability onset radius.

摘要： An electron accelerator including a resonant cavity, an electron source, an RF system, and at least one magnet unit is provided. The resonant cavity further includes a hollow closed conductor and the electron source is configured to radially inject a beam of electrons into the cavity. The RF system is configured to generate an electric field to accelerate the electrons along radial trajectories. The at least one magnet unit further-includes a deflecting magnet configured to generate a magnetic field that deflects an electron beam emerging out of the resonant cavity along a first radial trajectory and redirects the electron beam into the resonant cavity along a second radial trajectory. The resonant cavity further includes a first half shell, a second half shell, and a central ring element.

摘要： An electron accelerator is provided. The electron accelerator comprises a resonant cavity comprising a hollow closed conductor, an electron source configured to inject a beam of electrons, and an RF system. The electron accelerator further comprises a magnet unit, comprising a deflecting magnet. The deflecting magnet is configured to generate a magnetic field in a deflecting chamber in fluid communication with the resonant cavity by a deflecting window. The magnetic field is configured to deflect an electron beam emerging out of the resonant cavity through the deflecting window along a first radial trajectory in the mid-plane (Pm) and to redirect the electron beam into the resonant cavity through the deflecting window towards the central axis along a second radial trajectory. The deflecting magnet is composed of first and second permanent magnets positioned on either side of the mid-plane (Pm).

摘要： The present invention relates to a particle therapy apparatus used for radiation therapy. More particularly, this invention relates to a gantry for delivering particle beams which comprises means to analyze the incoming beam. Means are integrated into the gantry to limit the momentum spread of the beam and/or the emittance of the beam.
