ZS 1031-7A

Description

The process which effects the initial ionization within a flashlamp is know as "Triggering". Triggering creates a voltage gradient in the gas of sufficient magnitude to cause ionization of the lamps. Most flashlamp applications of ZS 1031-7A use a trigger coil to produce high voltage pulses of short duration, usually a few microseconds or less. Two different types of transformers and circuits have been developed which introduce this voltage to achieve ionization. ZS 1031-7A are namely series injection triggering and external triggering trigger coils. External triggering uses a high voltage trigger pulse to create a thin ionized streamer between the anode and cathode within the lamp. The coupling of this voltage to the lamp may be accomplished using a thin nickel wire wrapped around the surface of the lamp envelope. ZS 1031-7A trigger coils are generally lighter, smaller and less expensive than those of series injection triggering.
