Demonstration of the next generation of cancer therapy driver

为了实现下一代碳治疗，有必要开发一种完全剥离的碳离子源，从离子源释放的C-6+直接注入环形加速器环，并快速加速到所需的能量。在KEK和RIKEN BNL-BRANCH的合作下，成功地证明了一种具有足够离子束质量的激光烧蚀离子源。KEK数字加速器已被视为实现下一代碳治疗驱动器的模型加速器环，它不需要任何注射器系统，如RFQ、离子直线加速器和碳剥离器。低能束流传输、注入系统、环形磁励磁和感应加速系统的调谐已经从不同的角度进行了论证，所有的结果都发表在参考文献中，并在国内外会议上公布。五名硕士研究生通过相关活动获得了毕业论文。

It was necessary to develop an fully stripped carbon ion source in order to realize the next generation of carbon therapy, where C-6+ delivered from the ion source are directly injected into an circular accelerator ring and quickly accelerated up to an desired energy. A laser ablation ion source has been successfully demonstrated with a sufficient ion beam quality in a collaboration between KEK and RIKEN BNL-branch. The KEK digital accelerator has been examined as a model accelerator ring to realize the next generation of carbon therapy driver, which does not require any injector system, such as an RFQ, ion linac, and carbon stripper. Tuning of the low energy beam transport, injection system, and ring magnet excitation, and induction acceleration system has been demonstrated from various aspects.All results have been published in refereed papers and presented at domestic and international conferences. Five master students have earned their thesis through the related activities.
