Tore supra data acquisition: A system for long duration discharges

The Tore supra data acquisition system has been completely re-engineered (Guillerminet et al., 1996, Proceedings of the 19th Symposium on Fusion Technology, Lisbonne, 1996) over the last few years as part of the long duration discharge programme, and has been in operation since autumn 1996. It is based on a commercial package which provides all the basic modules required to build a distributed on-line software system, integrating the parameter loading, control, data acquisition, and real-time data displays. In this paper we examine the whole system, analyse the requirements to achieve continuous operation and discuss the favoured solution for Tore supra.
