Abstract:

An electronic servo was developed for injection time control of an electron synchrotron. It consists of a delay time command, an error detector, an integrator, an adder, a variable time delay unit, and a time-to-pulse-height converter. The servo works with electric potential analog and contains no mechanical movable parts except the delay time command Helipot. Timing errors of the controlled system the thyratron pulsing the synchrotron injector, together with its trigger circuit are converted into error voltage pulses and applied to the time delay unit for selfcorrection. The time-height converter is sensitive to letter than 1 part in 5000. This and the double-forwardpath control introduced make the regulated output extend from 3.5 to 8.5 microsec, and zero nsec error for steady timing errors in the controlled system and 10 nsec error for random fluctuations. The servo was built with transistors and was temperature compensated. The temperature stability is better than 5 nsecdegree C. Author
