An X-ray generator 7 directly connected to the electrode 8 internally of a hollow cathode 3 emits electrons under a field effect to generate X-rays, the generator 7 supplying 50 to 100 Kv with a rise time of less than 10 nanoseconds. X-rays rapidly created, in turn, rapidly create electrons in the active medium 1 between anode 2 and cathode 3 to trigger a discharge therebetween, across which anode and cathode the voltage of a laser capacitor is pre-applied at a level below the breakdown voltage of the active medium.
