To increase the electronbeamenergy for experiment, the symmetrical configuration of optical klystron is shifted to nonsymmetrical configuration.
为提高实验用电子束能量，将原光学速调管的对称结构改造为不对称结构。

It is also indicated that prebunching can short the laser wavelength without increasing the electronbeamenergy and relieve the requirement on the electronbeam quality.
同时还指出，预群聚有在不增加电子束能量情况下缩短激光波长和降低对电子束质量要求等作用。

The electron gun can achieve energy scan of electronbeam.
