介绍了在毛细管放电实验中采用预脉冲开关,成功地抑制了由于采用Blumlein传输线作为电流脉冲成形线时存在的前置固有脉冲对Z箍缩过程的破坏。同时成功地加载了预脉冲,建成了毛细管放电X光激光装置,实现了类氖氩46.9 nm软X光激光输出,准确地测量了激光波长,并对激光的一系列特性,包括激光的方向性、增益特性和束散角等进行了实验研究。这一装置提高了Marx发生器的使用效率,为进一步实现毛细管放电装置的小型化提供了一条有效的途径。此外还介绍了毛细管放电抽运机制可能的应用。
A method to eliminate the damage aroused by intrinsic prepulse of Blumlein transmission line is proposed.It is used as the forming line in the experiment of capillary discharge soft-X-ray laser,and an additional prepulse is loaded successfully.Ne-like Ar 46.9 nm soft-X-ray laser whose spectra detected by a Rowland spectrograph is obtained.We also detected the directionality,divergence and the gain characteristics of Ne-like Ar 46.9 nm soft-X-ray laser.With the help of Blumlein transmission line,the service efficiency of Marx generator is increased,which is helpful to achieving miniaturization of capillary discharge soft-X-ray.Finally,the supposed applications of 46.9 nm soft-X-ray are also discussed in this paper.
