Accelerator timing system
Abstract
An electron accelerator timing signal system providing synchronous operation of all apparatus, is described. Four timing signals, a 2 MHz clock frequency, a 2.5 kHz master pulse, a 10 Hz walk pulse, and a synchronous pulse are transported to the modulator stations. Triggers for the stations are divided from the 2.5 kHz master pulse to the appropriate modulator frequency; mutual synchronization is assured by the 10 Hz walk pulse. The synchronous pulse is also used for this purpose, on initiation by an operator or program. For triggering the beam synchronic apparatus and scopes, a seperate beam synchronous pulse, induced in a trigger modulator, is provided.
