Discharge Triggering

In order for the Febetron to be useful as a high voltage pulsed source, it must be possible to reproducibly predict the time delay between the occurance of an event-associated trigger signal and the discharge of the Febetron Pulser. A delayed trigger amplifier is used for this purpose, in which a trigger signal is shaped, delayed, and subsequently amplified to produce a suitable input pulse to the pulser trigger transformer.

The trigger transformer primary takes as input the 2,500 V amplified trigger signal from the delayed trigger amplifier, and outputs a 17,500 V trigger pulse to the trigger gap of the first Pulser Column stage.
