Development o 150MeV proton AG accelerator has been successfully completed in this study. The 150MeV proton AG accelerator consists of twelve magnets, each o which has a novel "return-york-free" configuration. We have successfully accelerated protons up to the maximum available energy in this ring with high repetition rate of 100Hz, which, is impossible or ordinary synchrotron and extracted them with high efficiency of more than 90%. We have made a basic experiment of fast spot scanning or future cancer therapy with high repetition beam and obtained a Bragg peak curve by measuring the depth-dependent dose. A new type of 2D detector or spot scanning with fiber scintillator and solid-state line sensing devices has been also successfully developed. In order to realize a small size FFAG ring in future, we have developed a prototype of novel super conducting magnet that composes of asymmetric coil configuration with newly developed computerized 6D coil winding machine (CNC). The magnetic field measurement has been carried out precisely or this prototype and the field quality was found to be excellent. We can summarize that this project has been successfully carried out and almost all issues that were aimed at the beginning have been completed with fruitful results.

本研究成功地完成了150MeV质子AG加速器的研制。150MeV质子AG加速器由12个磁铁组成，每个磁铁都有一个新的“无返回约克”配置。我们已经成功地加速质子到最大可用能量在这个环与高重复率为100赫兹，这是不可能的或普通的同步加速器和提取他们的高效率超过90%。我们进行了高重复率束流快速点扫描或未来癌症治疗的基础实验，并通过测量深度依赖剂量获得了布拉格峰曲线。一种新型的二维探测器或点扫描与光纤闪烁体和固态线传感器件也已成功开发。为了在未来实现小尺寸的FFAG环，我们已经开发了一种新型的超导磁体的原型，它由新开发的计算机化的6D线圈缠绕机（CNC）的非对称线圈配置。磁场测量已被精确地进行或该原型和磁场质量被发现是优秀的。我们可以总结说，这个项目已经成功地进行了，几乎所有的问题，在一开始就针对已完成，并取得了丰硕成果。
