A distributed real-time system for event-driven control and dynamic data acquisition on a fusion plasma experiment

摘要

A distributed real-time trigger and timing system, designed in a tree-type topology and implemented in VME and CAMAC versions, has been developed for a magnetic confinement fusion experiment. It provides sub-microsecond Time latencies for the transport of small data objects allowing event-driven discharge control with failure countereac- tion, dynamic pre-trigger sampling and event recording as well as accurate simultaneous triggers and synchronism on All nodes with acceptable optimality and predictability of timeliness.
