TEXTOR diagnostic data acquisition and processing in a distributed system environment

A distributed computer system configuration is used at the TEXTOR Tokamak experiment for control and data acquisition of the diagnostic systems as well as for processing of the experimental data. A cluster of VAX computers, interconnected by CI and Ethernet, form the network. VAX/VMS and DECNET form the basis for communication within the network. Interfacing with the process instrumentation is done through CAMAC. High data volumes are acquired, processed, and maintained. A description is given of the TEXTOR data acquisition system structure, performance, and status of implementation. The distributed nature of the system is outlined.<
