摘　　要：电子束心的横向运动：Ｃｏｒｋｓｃｒｅｗ施将君，李献文（中物院流体物理所，成都５２３信箱，６１０００３）摘要由于轴向引导磁场的存在，直线感应加速器中当束轴与磁轴有夹角时，束心要发生磁回旋运动。当电子束存在能散度时，束心的磁回旋运动演变成束心的ｃｏｒｋｓ...In a solenoidel focusing field,the centroid of any slice in an electron beam will execute cyclotron oscillation,if the magnetic-axis is tilted from the axis of accelerator.The energy variation within the beam pulse will make cyclotron osillation develope corkscrew oscillation.In this paper,the trajectory of beam centroid is analytically found,the expression of the effective radius for an electron beam is given,and the method to reduce corkscrew oscillation is simply discussed.
