ABSTRACT:
A circuit for igniting an electronic flashtube including a thyristor connected in series with the flashtube and an ignition capacitor connected through a switching thyristor to an ignition transformer to trigger the flashtube. The state of the series thyristor is controlled by means such as an electronic threshold switch to provide proper switching operation over a range of flashtubes with different specimen variations with respect to the time required to build up plasma.
