- accelerating heavy ions requires more power than accelerating light ions, so we first design an accelerator that accelerates to the energy required for carbon ions, which are heavy ions. With respect to light protons, an accelerator that accelerates to the energy required for carbon ions can be accelerated to the same energy as carbon ions by reducing the power. An injector system that accelerates and emits light to the same energy has been realized. However, the incident energy to the synchrotron is preferably higher for ions having a large charge mass ratio such as protons than for ions having a small charge mass ratio such as carbon ions. Conventionally, the design of heavy carbon ions was considered first, so there was no idea of realizing an injector system that emits carbon ions and protons with different energies with the same injector system.
- the present invention abandons the idea that an injector system optimized for ions with a small charge mass ratio is also used to accelerate ions with a large charge mass ratio, so that ions with a large charge mass ratio are synchrotron Realizes an injector system that accelerates different ions to different energies based on the opposite idea of using a part of the injector system that accelerates to a suitable incident energy for accelerating ions with a small charge mass ratio. did. Based on this idea, an injector system capable of emitting energy suitable as incident energy to the synchrotron for ions having a small charge mass ratio and ions having a large charge mass ratio could be realized in a small size.
- the present invention will be described by way of embodiments.
- FIG. 1 is a block diagram showing the configuration of a synchrotron injector system according to Embodiment 1 of the present invention.
- the synchrotron injector system 10 is a system that allows two types of ions to enter the synchrotron 7.
- the synchrotron injector system 10 includes a first ion source 1 that generates first ions and a second ion source 2 that generates second ions having a smaller charge-to-mass ratio than the first ions.
- a proton will be described as an example of the first ion
- a carbon ion will be described as an example of the second ion.
- the present invention can be applied to combinations of various ions as long as the charge mass ratio of the first ions is smaller than the charge mass ratio of the second ions.
- the transport path from the first ion source 1 until the protons are emitted and incident on the pre-accelerator 5 and the transport path from the second ion source 2 until the carbon ions are emitted and incident on the pre-accelerator 5 are summarized. This is referred to as a low energy beam transport path 4.
- the synthesizer 43 deflects the carbon ions from the second ion source 2 and joins them to the beam line 44.
- the carbon ions emitted from the second ion source 2 include carbon ions having different valences other than tetravalent.
- the accelerator accelerates only tetravalent carbon ions. For this reason, the configuration is such that only the tetravalent carbon ions are merged into the beam line 44 by deflecting the carbon ions from the second ion source 2 in the synthesizer 43.
- the pre-accelerator 5 is configured to accelerate incident protons or carbon ions to 4 MeV / u, for example. That is, the pre-accelerator 5 is an accelerator having a capability of accelerating both protons and carbon ions. Protons or carbon ions emitted from the pre-accelerator 5 are incident on the post accelerator 6.
- the post accelerator 6 is a self-focusing accelerator that does not include an electromagnet for focusing ions, such as an APF (Alternating-Phase Focusing) -IH (Interdigital-H) linear accelerator.
- the post accelerator 6 is configured to be able to accelerate the proton from 4 MeV / u to 7 MeV / u, for example.

If the beam diameter of the post accelerator 6, for example, the aperture diameter of the acceleration electrode or the like is larger than the beam diameter of the pre-accelerator 5, for example, the aperture diameter of the acceleration electrode, the carbon ions passing through the post accelerator 6 are electrodes or the like. It is possible to prevent the inside of the post accelerator 6 from being contaminated.
- the pre-accelerator 5 is configured such that carbon ions having a small charge-mass ratio have an energy suitable for carbon ions having a small charge-mass ratio as the incident energy of the synchrotron.
- the post accelerator 6 is configured to accelerate a proton having a large charge mass ratio to an energy suitable as the incident energy of the synchrotron. For this reason, carbon ions with a small charge mass ratio and protons with a large charge mass ratio can be accelerated and emitted to an energy suitable for the incident energy of the synchrotron as an injector that can inject two types of ions into the synchrotron.
- the injector system for synchrotron can be realized in a small size.
- FIG. FIG. 2 is a block diagram showing a configuration of a synchrotron injector system according to Embodiment 2 of the present invention.
