| 摘 要： | 讨论了有外加磁场情况下,强流相对论电子束传输过程中的电荷中和理论,着重讨论了二次电子逃逸时间和外加磁场对空间电荷中和的影响。得知当电子束半径大于2.0 cm 时,在计算空间电荷中和时间时就得考虑二次电子逃逸时间的影响。在一定条件下,外加磁场对空间电荷中和有阻碍作用,对于长漂移室,存在空间电荷中和允许的磁感应强度上限。

| Abstract: | The process of space charge neutralization of intense relativistic electron beam in an externally applied magnetic guide field is discussed in this paper,emphasis is given to the discusses of the es- cape of second electron and the influence of externally applied magnetic guide field on the process of space charge neutralization.This study demonstrated that the influence of the escape time of second electron on the time of space charge neutralization must be considered when beam radius is more than 2 cm.The externally applied magnetic guide field has the block effect on the process of space charge neutralization. |
