为实现碳离子放射治疗的快速三维扫描照射，发展了多能同步辐射装置。这种类型的操作可以在一个同步加速器循环中输出具有不同能量的各种碳离子束。在这种操作中使用的束流控制系统被开发为快速提供从照射控制系统所需的束流能量和强度。通过实验测试验证了系统的性能。该系统可在63 s内输出197种不同能量的光束。可以控制所有输出光束的光束强度，而没有大的波纹或过冲。并成功地进行了前列腺癌放射治疗的实验测试，测试结果证明，我们的系统可以大大减少照射时间。(C)2017爱思唯尔B.V.保留所有权利。
Multiple-energy synchrotron operation was developed to realize fast 3D scanning irradiation for carbon ion radiotherapy. This type of operation can output various carbon-ion beams with different energies in a single synchrotron cycle. The beam control system used in this kind of operation was developed to quickly provide the beam energy and intensity required from the irradiation control system. The performance of the system was verified by experimental tests. The system could output beams of 197 different energies in 63 s. The beam intensity could be controlled for all the output beams without large ripples or overshooting. The experimental test of irradiation for prostate cancer treatment was also successfully performed, and the test results proved that our system can greatly reduce the irradiation time.
