| 摘 要： | 正在研究的1Hz重复频率电子束泵浦HF/DF化学激光器，预期产生的电子束能量为0.5MeV、束流强度为100kA、束流脉冲宽度为100ns。在该系统设计中，使用了一个脉冲变压器来对脉冲成形水线进行双共振充电。脉冲变压器的初级、次级电感与互感分别为331nH，26.5μH与1.9μH。脉冲成形线的电容、电感与阻抗分别为8.15nF，300nH与6.2Ω。脉冲成形线在1MV的峰值充电电压下的击穿因子为0.3。在3.3%的能量转换效率条件下，预期可以产生的HF/DF激光脉冲能量为２50J以上。

| Abstract: | A 1Hz repetition-rate electron beam generator is being developed to pump HF/DF chemical laser. The pulse width, peak current and peak voltage of the electron beams are 100ns, 100kA and 450kV, respectively. It uses two diodes, two water-filled pulse forming lines, three laser-triggered switches, a pulse transformer and one set of energy storage capacitors. The primary, secondary and mutual inductances of the pulse transformer are 331nH, 26.5mH and 1.9μH, respectively. The capacitance of each pulse forming line is 8.15nF. Its inductance and impedance are 300nH and 6.2Ω, respectively. The breaking factor is 0.3 at 1MV charging voltage. The output energy of a non-chain HF/DF chemical laser pulse is expected to be 250J at 3.8μm. |
