| 摘 要： | 天光一号预放大器是Φ12cm口径的电子束双向泵浦KrF激光双程放大器。通过调整二极管阴阳极间距，获得了从Marx发生器到二极管的最大能量传输效率和较小的后脉冲。研究了不同阳极材料和气室中不同气压下，电子束在气室中的能量沉积以及阳极膜和压力膜的寿命，并分析了膜损伤原因，将预放大器的实验条件进行优化，使预放大器能长期稳定的工作。

| Abstract: | Heaven 1 pre-amplifier is a double pass, double sided electron beam pumped KrF laser system. The largest energy transmission efficiency from the Marx generator to the diodes and smaller post-pulse were obtained by optimizing the anode-cathode gap. The energies deposited in the gas were investigated as a function of Marx voltage for both 30pm Al and 20pm Ti anode foils at 0. 10, 0. 15, 0. 20 and 0. 22 MPa cell pressures. The investigation was performed for the same 35pm Ti pressure foil. The lifetimes of the anode and pressure foils were studied and the damage causes of the anode and pressure foils were analyzed. The optimization of experimental conditions for a long time operation was realized. |
