[0011] 一种使用质子或重离子束治癌装置的方法,其主要步骤为: [0011] A method using a proton beam or a heavy ion cancer therapy apparatus, the main steps of:

[0012] (I)由ECR离子源产生离子束,在吸极高压20KV-40KV将束流引出,经过glasser透镜的匹配后注入到射频四极直线加速器进行预加速或射频四极直线加速器将离子加速到2-2.5MeV/u,然后继续匹配到漂移管直线加速器进行加速,到达同步加速器的注入能量为4MeV/u-7MeV/u后,再经过匹配和传输,将束流配送到同步加速器入口; [0012] (I) produced by the ECR ion source of an ion beam in absorbing extreme pressure 20KV-40KV beam will lead, after a lens implantation glasser matching to the radio frequency quadrupole linear accelerator is pre-accelerated or radio frequency quadrupole linear ion accelerator accelerated to 2-2.5MeV / u, then continue to match the drift tube linear accelerator accelerates, the implantation energy synchrotron is 4MeV / u-7MeV / u after the matched and then transmitted to the synchrotron beam delivery inlet ;

[0013] (2)束流到达同步加速器入口后,利用同步加速器内的凸轨使环内束流轨道凸起,使凸轨高度与同步加速器第一静电偏转板离真空管道的距离相当。 After [0013] (2) synchrotron beam reaches the inlet, the convex rail within the inner ring of the synchrotron so that the projection beam orbit, so that the first bump height synchrotron electrostatic deflection plates considerable distance from the vacuum line. 当束流注满同步加速器一圈后,凸轨高度开始下降,下降时间28-30微秒,等于输入圈数乘以回旋周期),以实现束流的多圈注入,注入圈数为15-30圈; When the synchrotron beam filled circle, the bump height to begin to decline 28-30 microseconds time, the number of turns equal to the input multiplied by the swirling cycles) to achieve a plurality of turns of the beam injection, the number of turns of the injection 15 30 laps;

[0014] (3)束流注入到同步加速器后,通过高频腔对束流进行俘获和加速,根据终端的治疗和实验需要,将束流加速到预定能量,对于质子为70-250MeV,对于重离子为100-400MeV/u ;同时,将束流的水平工作点逐步移动到1/3共振线附近; After [0014] (3) is injected into the synchrotron beam, RF cavity by acceleration of the beam and the capture, treatment and according to the experimental needs of the terminal, the beam will be accelerated to a predetermined energy for protons 70-250MeV, for heavy ion 100-400MeV / u; at the same time, the horizontal beam gradually moves the operating point to the vicinity of 1/3 of resonance line;

[0015] (4)束流到达预定能量后,六极铁电流开始增大,使同步加速器的稳定相空间缩小到大于束流的发射度; After [0015] (4) reaches a predetermined beam energy, current begins to increase iron hexapole, stabilize the phase space reduced to the degree of emission of the synchrotron is greater than the beam current;

[0016] (5)开启横向射频激励,束流在横向电场的作用下,发射度增大,从而到达不稳定区,继而束流发射度沿着不稳定区的分界线迅速增大,从而到达静电偏转板被引出; [0016] (5) open transversely RF excited, the beam under the action of the transverse electric field, emittance is increased to reach the unstable region, then rapidly increases along the emittance unstable boundary region, so as to reach electrostatic deflection plates are drawn out;

[0017] (6)引出束经过同步加速器的第2静电偏转板和第2切割磁铁,输送到高能束线,经过高能束线的配送,到达治疗或实验终端,进行相关治疗或实验。 [0017] (6) leads through the synchrotron beam electrostatic deflection plates and the second cutting the second magnet, the high energy beam transport line, through high energy beam distribution line, reaches a terminal or experimental treatment, or treatment related experiments.

[0018] (7)终端有效剂量达到预设值时,可以通过停止横向激励的作用来停止束流的继续引出。 When [0018] (7) an effective dose of the terminal reaches a preset value, the beam can be stopped by stopping action continues transversely excited drawn.

[0019] 本发明的有益效果是: [0019] Advantageous effects of the present invention are:

[0020] 1.采用同步加速器比采用其他装置具有更大的优势。 [0020] 1. The use of other means than using synchrotron has more advantages.

[0021]目前的主流加速器共分成三类,分别是直线加速器,回旋加速器和同步加速器。 [0021] The current mainstream accelerator were divided into three categories, namely linear accelerator, synchrotron and cyclotron. 采用直线加速器可以做到束流强度的变换,但把束流加速到同样能量的直线加速器的造价是同步加速器的好几倍。 Transformation can be done using the linear accelerator beam intensity, but the cost of the beam is accelerated to the same energy linear accelerator several times synchrotron. 回旋加速器造价较低,但无法实现能量的快速变换。 Cyclotron low cost, but can not achieve rapid transformation of energy. 而采用同步加速器可以根据终端的需要迅速的变换引出束流的能量和强度,相比回旋和直线加速器而言,要简单和方便,且更为经济。 May be transformed using the synchrotron beam energy and intensity lead terminal according to the needs of rapid, compared in terms of rotating and linear accelerator, to simple and convenient, and more economical.

[0022] 2.采用直线加速器做注入器的设计可以获得较高的注入流强。 [0022] 2. The use of a linear accelerator injector design can be done to obtain a strong high injection flow.

[0023] 采用直线加速器作为注入器比采用回旋加速器作为注入器最大的优势在于直线加速器可以提供更高的流强(是近物所目前的SFC回旋加速器束流强度的20倍以上)和更小的束流发射度。 [0023] The linear accelerator as the injector than the use of a cyclotron is the advantage that the maximum injection linear accelerator can provide higher current intensity (almost 20 times more than the present composition SFC cyclotron beam intensity) and smaller the emittance. 越高的注入流强可以使同步加速器在注入同样的圈数下,获得越多的离子数;越小的注入束流发射度,可以在较小的同步加速器横向孔径的情况下注入较多的圈数,亦即获得较多的注入离子数。 The higher the injection current intensity synchrotron injection can be made at the same number of turns, the more the number of ions obtained; the smaller emittance injection, may be injected in the case of smaller more lateral apertures of the synchrotron the number of turns, i.e., implanted ions is obtained more. 这样便可以节约同步加速器真空室的横向孔径,进而减小同步存储环的造价。 This makes it possible to save the transverse aperture synchrotron vacuum chamber, thereby reducing the cost of storage rings synchronization.
