DESIGN AND COMMISSIONING OF THE ISAC CONTROL SYSTEM AT TRIUMF

The control system for the initial stage of the ISAC radioactive beam facility at TRIUMF was recently commissioned and the facility delivered the first radioactive beam to users in December of 1998. The control system is based on the EPICS toolkit. VME based Motorola MVME162 CPUs serve as input/output Controllers, SUN workstations as application servers, and PCs are used with X-terminal software as operator interface stations. Modicon PLCs control the vacuum system and ion sources. A network of CAN-bus based controllers is used for the beam guidance system. Custom VME modules were developed for beam diagnostics.
