The Beam-Programming System of the Bevatron

A brief description is given of the beam-progromming equipment developed for the Bevatron. The system described provides analog-computer-controlled as well as beam-controlled frequency tracking. Equipment is described that permits arbitrary adjustment and control of the radial position of the circulating beam at any energy. Beamintensity control and the automatic reduction of phase errors in the acceleration system are provided. Included also are units that produce long and short beam pulses. Equipment that permits highly multiple operation is also discussed. The integration of these equipments for extended injection is treated.
