摘要

2000年9月，筑波大学新质子治疗系统开始进行束流调试。目前的系统采用一个最大能量为250兆电子伏的同步加速器和两个旋转龙门。激光束被成功地加速到250 MeV并传输到辐照喷嘴。利用筑波大学开发的双环双散射方法，证实了同步加速器提取的光束位置非常稳定，并实现了照射区域足够的平整度。此外，还成功实现了由患者呼吸信号触发的同步加速器操作。

Beam commissioning of the new proton therapy system for University of Tsukuba

Beam commissioning of the new proton therapy system for University of Tsukuba was started in September 2000. The present system employs a synchrotron with a maximum energy of 250 MeV and two rotating gantries. The beam was successfully accelerated up to 250 MeV and transported to the irradiation nozzles. The position of the beam extracted from the synchrotron was confirmed to be very stable and sufficient flatness for the irradiation area was realized by using the dual ring double scattering method developed at University of Tsukuba. Furthermore, synchrotron operation triggered by patient respiration signal was succeeded.
