Abstract
The new computer control system has operated the heavy ion accelerator GANIL from the beginning of 1993 and has reached a state of routine operation. It supersedes the obsolete initial system to cope with the harsh experimental conditions required by the very high intensity beams expected in the near future. Hardware and software implementations, as well as the human interface, are presented. Emphasis is placed on the three-layer distributed architecture adopted. An Ethernet local area network (LAN) links the basic components: a VAX/VMS cluster, XWINDOWS-interfaced operator consoles, VAXELN-driven CAMAC crate controllers and programmable logic controllers for the front end controls. Also the data management, through the INGRES relational database management system (RDBMS), as well as the operating software written in ADA, are described. The early experience with the new control system is reported and future developments discussed.
