【摘要】：高温高密度等离子体辐射源产生脉冲X射线的同时还产生等离子体碎片,飞散速度分布在0.1~10km/s。研制电磁驱动超高速机械快门,有效通光孔径为40mm×50mm,利用45mm×60mm×100μm的铝膜作为快门叶片,在放电电压20kV、驱动电流80kA、放电周期18μs条件下,获得的快门关门时间小于180μs。将快门放置在距离等离子体X射线源2m处,X射线通过后在180μs时间内关闭光学通道,以阻挡高温高密度等离子体产生的碎片,保护X射线精密探测系统和样品,同时实现等离子体参数的精密测量。
[Abstract]:The high temperature and high density plasma radiation source produces the pulsed X ray and also produces the plasma fragment. The dispersion velocity is 0. 1 ~ 10 km / s. An electromagnetically driven ultra-high speed mechanical shutter was developed. The effective aperture of the shutter was 40mm 脳 50mm. Using aluminum film of 45mm 脳 60mm 脳 100 渭 m as shutter blade, the shutter closing time was less than 180 渭 s under the conditions of 20 kV discharge voltage, 80 Ka driving current and 18 渭 s discharge period. The shutter is placed at a distance of 2m from the plasma X-ray source to close the optical channel within 180 渭 s of the X-ray passing through, in order to block the fragments produced by the high-temperature and high-density plasma, and to protect the X-ray precision detection system and samples. At the same time, the precise measurement of plasma parameters is realized.
