摘要
本文研究了一种用于能量连续可调辐照加速器(1.2~12 MeV)的新型驻波加速结构,该新型加速结构由两部分组成:低速加速部分和高速加速部分。为了使这种新的加速结构能按要求工作,我们首先要研究相应的高频率低电平矢量控制方法以及相应的幅度反馈控制算法和相位反馈控制算法。当高频信号的幅度和相位稳定后,低电平控制系统需要调节高能功率分配器,使它输出要求的能量。同时,场控制环路和能量调节环路的一致性需要精确调节,论文讨论了该关键问题,解决了辐照加速器的能量连续可调的难题。
A new standing-wave accelerating structure has been developed,which is used for a variable output-energy irradiation accelerator(1.2 MeV~12 MeV).The new accelerating structure is composed by two parts:low-velocity section and high-velocity section.In order to make the new accelerating structure work well,we should study the according high frequency low-level vector control method(the magnitude feedback control algorithm and the phase position feedback control algorithm).At the same time,when the magnitude and phase of the high frequency signal are stable,the low-level control system need to adjust the high-power splitter,and make it export a precise and preset power.So the consistency of the field-control circuit and the power adjusted circuit should be developed.The destination of the application project is to fix the key issues and implement the irradiation accelerator's output-energy continuously adjusting.
