Abstract : Pulse transformers are often employed in circuits which are used to trigger spark gaps. There are limitations in the use of this type of generator when a high degree of accuracy is desired. To operate large-area, high-power light sources with Kerr cell shutters for the photography of high-velocity particle impacts, synchronization of the light source and shutter must be accomplished with a jitter of no more than a few millimicroseconds. Pulse requirements and spark-gap conditions for millimicrosecond triggering are defined. Several transformerless, trigger-pulse generators are described. One of these has been used to trigger 50-kilovolt spark gaps with jitter times as low as 2 millimicroseconds. A number of techniques for synchronizing the firing of spark gaps are discussed, and some uses of these techniques are given. Several methods for pulsing Kerr cells using accurately triggered spark gaps are also described. (Author)
