摘要： The present application provides a cyclotron and a high-gain, high-precision method for accelerating α particles and H 2 + particles. The cyclotron comprises a dual ECR ion source system, a dual-beam injection and transmission system based on magnetic analyzer, a main magnet system, a high-frequency system based on 8th harmonics, and a dual-beam extraction system for precise control of α beam energy using deflector. The high-gain method includes doubling the frequency of the RF cavity, reducing the cavity height and the angle of the dees by half compared to the 4th harmonic high-frequency cavity, and adapting the internal rod diameter, cavity outer radius, angle width, and dees thickness accordingly. The high-precision method includes setting the beam extraction point position, observing the radial distribution of the beam on the target, and adjusting the deflector position in real-time during beam commissioning. In the present application, a cyclotron capable of accelerating alpha and H 2 + particles is developed for the first time in the world; a double-beam high-brightness merging injection of the particles and the H 2 + particles is realized for the first time, and a compact cyclotron uses an eighth-harmonic high-frequency cavity for acceleration for the first time.

摘要： The present disclosure relates to an undulator device (300) comprising:
- at least a first superconducting coil structure (302); and
- at least a second superconducting coil structure (304) positioned opposite the first superconducting coil structure; wherein the first and second superconducting coil structures are separated by a gap (h g ) dedicated to the passage of an electron beam having an electron beam trajectory (314) around a beam axis (310), the beam axis being in a first direction (X) ;
wherein each superconducting coil structure includes at least a groove (332, 334) through the thickness (h m ) of said superconducting coil structure to separate it into a plurality of elementary coils; the at least one groove being configured in such a way that a current flowing in the superconducting coil structure between the at least one groove can flow alternately in two different orientations, for example into substantially two opposite orientations, in said superconducting coil structure.

摘要： There is provided a circular accelerator that accelerates a beam of charged particles circulating in a magnetic field such that a closed orbit for each energy of the beam is eccentric. The circular accelerator includes a beam extraction port for extracting beams of different energies from the closed orbit, a first bending magnet and a second bending magnet that bend the beam extracted from the beam extraction port, and a control unit that controls magnetic field strengths of the first bending magnet and the second bending magnet in accordance with the energy of the extracted beam. When the energy of the extracted beam is a designed maximum energy of the circular accelerator, the control unit excites both the first bending magnet and the second bending magnet to bend the beam.
