Design for steady state operation of LHD diagnostics control system
Description
The LHD project is planning to have the long-pulse plasma experiments of about an hour in addition to the 10-second short-pulse experiments. These operations require the realtime control and monitor system along with the ordinary CAMAC system, and the distributed VME computers with their realtime operating system Tornado (VxWorks) will be individually applied for the LHD 20 or 30 kinds of diagnostics. The substantial limitation of the realtime systems that they are inevitably poor at fast data sampling requires the iterative CAMAC data acquisition for the precise sampling of physical analysis. These functional separation between the batch data acquisition by CAMACs and the realtime device management by VMEs is the essential idea of the long-pulse operation of the LHD data processing system.
