Effect of pulse feed-in mode change on beam transport

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.
