Abstract
AC powered flash tube control circuitry includes an energy storage circuit and a firing circuit. The storage and firing circuits are triggered in each flash cycle in separate coordinated sequence in time synchronism with the frequency of the AC source to store energy in a first portion of each flash cycle and to trigger the tube into conduction in a second portion of the flash cycle during which energy from the storage circuit is discharged from the flash tube to produce an output flash of radiation.
