高功率（~50TW）短脉冲（20fs）激光离子生产过程将被用作癌症治疗同步加速器的紧凑型注入器。在该方案中，在能量空间内对激光产生的离子束施加频率为160 MHz的射频电压，使动量扩散降低到±1%，通过电子束冷却进一步冷却到±0.1%，以实现脉冲同步加速器安全加速光束所需的特性。
Ion production process with a high-power (~50TW) short-pulse (20fs) laser is to be utilized as a compact injector of the synchrotron for cancer therapy. In the scheme, an RF voltage with the frequency of 160 MHz is applied to the laser produced ion-beam within the energy space to reduce the momentum spread to ±1%, which is further cooled down to ±0.1 % by an electron beam cooling to realize needed characteristics of the beam to be safely accelerated by a pulse synchrotron.
