Development of a Safety Classified SystemWith LabView and EPICS

Abstract : The Spiral2 linear accelerator will drive high intensity beams, up to 5 mA and 200 kW at linac exit. In tuning phase, or when not used by the experimental areas, the beam will be stopped in a dedicated beam dump. To avoid excessive activation of this beamdump, in order to allow human intervention, a safety classified system had been designed to integrate the number of particles dropped in it within each 24 hours time frame. For each kind of beam, a threshold will be defined and as soon as the threshold is reached a beam cut-off will be sent to the machine protection system. This system, called SLAAF: System for the Limitation of the Activation of the beam dump (Arret Faisceau in French) rely on LabView and EPICS (Experimental Physics and Industrial Control) technology. This paper will describe the specification and development processes and how we dealt to meet both functional and safety requirements using two technologies not commonly used for safety classified systems.
