Abstract: In a continuation of experiments reported at the last High-Speed Congress (1958) the authors study the conditions that determine the maximum frequency of periodic discharges through a flash x-ray tube. With the earlier device, using direct triggering of the tube and simple R-C or R-L-C recharging, the limit frequency is about 5000/sec. To get a higher rate, it is necessary to isolate the anode from the discharge condenser during the pauses. In the new circuit this controlled separation is attained by a quenched spark gap, which is periodically triggered by an electronic pulse generator. The device allows a precise control of frequency and total frame number. A capacitive voltage divider assures the synchronized pulses to the tube trigger electrode. With an apparatus following this principle, periodic x-ray flashes up to 12,000/sec and a total number of 60 were produced. Image separation is accomplished by means of a drum camera running at 80 m/sec. As applications, the authors show a frame series of the initiation of a squib and of the liquid metal transition in arc welding.
