Abstract

This paper describes the control and diagnostic systems for the new LNLS 500-MeV booster synchrotron. The LNLS light source is operated with a home made local controller system (LOCO), using Z80-based CPU modules that run a general software to handle the interface boards. Although the overall structure of the low-level software was unaltered for the LNLS booster synchrotron, time constraints required many tasks previously executed by the high-level software to be transferred to local CPU modules. These modules now make decisions at critical moments in the injection process and the low-level software handles orbit measurement during the energy ramp. A new network board was designed to improve the reliability and speed of the communication between the low- and high-level software
