摘　　要：利用加速器原有的束流传输及检测系统,在单脉冲直线感应加速器上分别对双边馈入和单边馈入情况下强流束的传输情况进行了实验测量。实验结果表明:在改变加速脉冲的馈入方式后,传输过程中电子束在加速段的束心位置发生了明显改变,将对加速器的束流输运产生非常不利的影响。通过对实验数据的比较和分析,提出了传输线延时产生双脉冲可能采用的脉冲馈入方案。By using the existing beam transport and detection system,experiments have been done to detect the change in the single-pulse linear induction accelerator（LIA） beam transport when the pulse symmetrical feed-in mode changes into the unilateral one.The results show that changing the pulse feed-in mode will result in a visible offset of the electron beam center in the acceleration segment.Thus the pulse unilateral feed-in mode will markedly disturb the beam transport of an LIA.According to the experiments,some feasible improvements have been advanced about the pulse feed-in mode for the double-pulse LIA based on cable delay.
