Abstract

The invention relates to an accelerator which combines a cyclotron and a synchrotron and is used for cancer therapy with protons-heavy ion beams, comprising an ion source E and the synchrotron C. The accelerator is characterized in that the synchrotron C comprises a septum magnet implanting device (5), a septum magnet extracting device (6), a radio-frequency accelerating device (9), eight bendingsections of the synchrotron (1-1 to 1-8) and eight straight sections of the synchrotron (2-1 to 2-8), which are connected by an ion beam transmission line F; the ion beam implantation end of the synchrotron C is provided with a sector focusing cyclotron A or / and a separated sector focusing cyclotron B. By adopting the method of combining the cyclotron and the synchrotron, a set of accelerator devices required by cancer therapy with protons and heavy ion beams is set up to realize the requirements of clinical therapy on beam parameters; the mass numbers of the protons and the heavy ions are less than or equal to 40; the protons and heavy ion beams have wide energy range from 10MeV / u to 400MeV / u and high flux (the ion number provided by each pulse is up to 10<7-10> magnitude).

Description

Technical field:

[0001] The invention relates to the technical field of a proton-heavy ion beam cancer treatment device combining a cyclotron and a synchrotron, in particular to an accelerator for proton-heavy ion beam cancer treatment. Background technique:

[0002] Proton-heavy ion Beam cancer treatment has become an advanced and effective cancer radiotherapy method in the world today. At present, the results of preliminary clinical treatment trials show that proton-heavy ion beam therapy has a very significant curative effect on cancer, and there is no obvious side effect.

[0003] In the implementation of proton-heavy ion beam irradiation therapy, an accelerator that provides a beam that meets clinical requirements is the most basic device. According to the depth of different tumors in clinical treatment, the accelerator needs to provide ion beams with different energies; according to the shape of different tumors, the accelerator needs to be able to precisely control ...
