研究了激光引发真空火花的工作特性，并参考其X射线发射。该系统采用快速电容器组（电流上升时间=1 μs），输入能量为4.4kJ。这里的研究表明，对于这样的系统，可以调整系统参数，以获得令人满意的X射线发射再现性方面的最佳操作。可以观察到，通过选择正确的V-d组合，可以始终获得强X射线点源，其中V是放电电压，单位为千伏，d是电极间距，单位为毫米。对于本系统，发现该组合为20-5，并且在该系统中实现了优于80%的X射线再现性。
The operational characteristics of a laser‐initiated vacuum spark is studied with reference to its x‐ray emission. The present system employs a fast capacitor bank (current rise time=1 μs) with input energy of 4.4 kJ. The studies here show that for such a system, the system parameters can be adjusted for satisfactory optimum operation with respect to x‐ray emission reproducibility. It is observed that intense x‐ray point sources are obtained consistently by choosing the right V–d combination, where V is the discharge voltage in kilovolts and d is the electrode separation in millimeters. For the present system, this combination is found to be 20–5 and a x‐ray reproducibility of better than 80% has been achieved in this system.
