Microcomputer control system for the SuperHILAC third injector

A new control system using the latest technology in microcomputers will be used on the third injector at the SuperHILAC. It incorporates some new and progressive ideas in both hardware and software design. These ideas were inspired by the revolution in microprocessors. The third injector project consists of a high voltage pre-injector, a Wideroe type linear accelerator, and connecting beam lines, requiring control of 80 analog and 300 boolean devices. To solve this problem, emphasizing inexpens… more
