摘要
基于RFQ加速器中束流横向运动方程描述了一种计算其入口处束流接受度的方法 .针对特定结构参数的四翼型RFQ加速器 ,给出了计算结果为 :加速质子束时的系统接受度在x x′平面为0 .0 15 3cm·rad ,在y y′平面为 0 .0 114cm·rad .此方法也适用于求解其它已知结构、使用射频场加速、线性横向电场的加速器的接受度 .
A method based on the transverse particle motion equation is described for the calculation of beam acceptance for RFQ accelerators. The result is given for a four-vane type RFQ accelerator with specific structure parameters. The system acceptance for proton beam is 0.0153 cm·rad in x-x′ phase space, and 0.0114 cm·rad in y-y′ phase space. The method can also be applied for the calculation of acceptance for other RF accelerators with known structures and linear transverse electric fields.
