1脉冲化注入线装置的总体方案开展连续波束流脉冲化技术研究,目标是实现基于强流回旋加速器的连续波质子束的脉冲化。为此,首先在注入线上安装脉冲化装置,实现几十keV量级的强流负氢束的脉冲化,然后再将脉冲化后的负氢束注入回旋加速器加速到需要的能量后,通过回旋加速器引出脉冲质子束。设计的脉冲化注入线装置可将70MHz(10MeV强流回旋加速器的高频频率)连续波负氢束脉冲化为重复频率4.4MHz、脉冲宽度小于10ns的脉冲束。基于强流回旋加速器的连续波束流脉冲化的实施方案
The overall program of a pulsed injection line device to carry out continuous beam pulsed technology research, the goal is to achieve pulsed pulsed continuous-wave proton beam based on a strong current cyclotron. To this end, first, a pulsed device is installed on the injection line to pulsate a heavy current negative hydrogen beam with the order of tens keV, and then inject the pulsed negative hydrogen beam into the cyclotron to accelerate to the required energy and then pass The cyclotron leads to a pulsed proton beam. A pulsed injection line designed to pulsate a continuous-wave negative hydrogen beam of 70 MHz (high frequency of a 10MeV high-intensity cyclotron) into a pulsed beam with a repetition rate of 4.4 MHz and a pulse width of less than 10 ns. Implementation of continuous beam pulsing based on strong current cyclotron
