Embodiment 1
[0031] Embodiment 1: a kind of operation method that eliminates the hysteresis effect influence of synchrotron, see Figure 5 , including the following steps:
[0032] 1) According to the treatment needs of different tumor cells of the user 1, determine the highest energy 2 of the beam required by the synchrotron, and set it as the highest energy value of the beam required by the synchrotron to run the magnetic field circulation mode;
[0033] 2) The beam energy setting module 2 is connected to the calculation module 3; the calculation module includes a dipole magnet parameter calculation module 3-1, a quadrupole magnet parameter calculation module 3-2, and a hexapole magnet parameter calculation module 3-3; The calculation module 3 is also connected with the local database parameter module 10; according to the beam injection, the highest energy value of the extraction energy setting and the magnetic field circulation mode, combined with the synchrotron physical simulation calcu...
Embodiment 2
[0044] Example 2: The method of the present invention will be described by taking the implementation of a tumor cell therapy in this invention as an example. First, it is assumed that the beam energy required for this tumor cell therapy is 200 MeV / u, 300 MeV / u, 430 MeV / u.
[0045] The operating process of the device of the present invention is described as:
[0046] 1. ECR ion source provides 12 C 4+ , is accelerated to an energy of 7.0 MeV / u by the sector-focused cyclotron SFC (energy constant K=69), and is delivered to the entrance of the main ring of the cooling storage ring CSR with a flow intensity of 10 microamperes.
[0047] 2. Using the strip-injection method, the 12 C 4+ stripped into 12 C 6+ Injected into the CSR main ring, the energy is 7.0MeV / u. According to the needs of tumor cell therapy, the highest energy of the magnetic field circulation mode is determined to be 430 MeV, and the energy of tumor therapy is 300 MeV for example. The injection energy is 7.0...
