项目摘要

An accelerator system of particle cancer therapy was constructed by the accelerator technology of the 20th century. Therefore, the system is large and complex. We tried new accelerator technology of the 21st century for accelerator system of cancer therapy. These new technologies are Direct Plasma Injection Scheme (DPIS), Alternating Phase Focusing (APF) method of drift tube acceleration structure and 3-dimensional analysis of acceleration cavity.A laser ion source was studied and developed for gas and solid target. We-succeeded product of high intensity ion by combining a cryogenic-cooler and a YAG laser. The results were contributed and published in international conference and international journal, respectively. We carried out the experiment with Direct Plasma Injection Scheme for APF Interdigital-H (IH) linear accelerator which was designed to accelerate ions with charge to mass ratio (q/A) of 1-1/3 from 40 keV/amu to 2 MeV/amu. We found that the improvement was necessary to realize large acceptance from the result of particle trajectory calculation. In order to decrease the cost of improvement, the liner accelerator cavity was modified as small as possible. In acceleration test in low energy injection, the APF-IH linear accelerator could not to get large acceptance by Direct Plasma Injection Scheme with laser ion source. Therefore, a hybrid single cavity linear accelerator was designed as new conception. A Radio Frequency Quadrupole (RFQ) type having good focusing performance in low energy region and a drift tube type having good acceleration performance in medium energy region were installed in a single cavity. Design study of the hybrid single cavity linear accelerator was contributed and published for International conference and International Journal, respectively.

An accelerator system of particle cancer therapy was constructed by the accelerator technology of the 20th century.因此，系统大而复杂。我们尝试了21世纪的新加速器技术，用于癌症治疗的加速器系统。这些新技术是直接血浆注入方案（DPI），交替的相聚焦（APF）漂移管加速度结构的方法和加速腔的3维分析。对气体和固体靶标进行了激光离子源。通过将低强度离子和YAG激光器结合使用，我们成功地获得了高强度离子的产物。结果分别在国际会议和国际杂志上发表。我们对APF间digital-H（IH）线性加速器进行了直接血浆注射方案进行了实验，该实验旨在加速质量比（Q/A）为1-1/3的离子，从40 KeV/AMU到2 MEV/AMU。我们发现，从粒子轨迹计算的结果中，必须进行改进才能实现大量接受。为了降低改善成本，将衬里加速器腔尽可能小。在低能注入的加速度测试中，APF-IH线性加速器无法通过激光离子源直接血浆注射方案获得大量接受。因此，混合单腔线性加速器被设计为新概念。单个腔中安装了一种在低能区域的射频四极杆（RFQ）类型在低能区域中具有良好的聚焦性能和在中能区域具有良好加速度性能的漂移管类型。混合单腔线性加速器的设计研究分别为国际会议和国际杂志撰写。
