本文给出在实空间为平面曲线坐标和相空间为六维循环坐标的情况下,离子束团在静磁光学元件的六维相点运动方程组,从此方程出发导出了偏转磁铁的六维线性传输矩阵,并进而给出了由于横向对纵向的耦合效应所引起的脉冲宽度修正公式。 In this paper, the equations of six-dimensional phase point motion of the ion beam cluster in the magnetostatic optical element under the condition that the real space is the plane curve coordinate and the phase space is the six-dimensional cyclic coordinate are derived. From this equation, the six-dimensional linearity Transfer matrix, and then gives the pulse width correction formula due to the lateral to longitudinal coupling effect.
