Abstract :
The TFTR neutral beam computer system has expanded to provide an easy-to-use windowing and graphics environment for running the TFTR neutral beam injection system for D-T operations. Two SUN workstations are used for interactive analysis and display of neutral beam diagnostic and operational data. These systems are interfaced via Ethernet to another SUN computer which is used for data transfer and real-time analysis. The real-time analysis computer is linked to the TFTR Encore computer system via a DMA interface. Data acquisition and device control is performed on the Encore computers, and raw data is transferred via a memory-mapped approach to memory partitions and files on the SUN Analysis computer. Real-time analysis programs provide numerous displays to operators and engineers of operational data every 150 seconds. Physicists use X-window and OSF/MOTIF-based graphical user interfaces (GUIs) on the Diagnostic workstation to display interactive analysis of diagnostic data. These include X-window graphical displays of thermocouples, OMA, waterflow calorimetry, H-alpha duct and ion gauge data to the workstation. Neutral beam operations engineers also use a similar GUI to display interactive summary, power and ion source waveforms on the Operations workstation. In addition, these engineers have access to INGRES databases, which contain operational and analyzed data for the past several TFTR run periods. The Operations computer has a hard disk drive, which contains these INGRES databases and a database of restored analysis and raw data files. These files can be restored on demand from the TFTR computer system VAX cluster. The real-time Analysis computer also has a hard disk drive, which contains a database of the most recent analysis and raw data files
