The TFTR Charge Exchange Diagnostic Software Systems

This paper describes the applications software systems for computer control and monitoring of diagnostic hardware, and for data acquisition and analysis of the TFTR (Tokamak Fusion Test Reactor) Charge Exchange diagnostics. The TFTR Charge Exchange diagnostics are comprised of two autonomous systems, each consisting of up to six independent analyzer modules viewing the plasma at different angles and toroidal locations. Each system will have the capability of acquiring up to 2.5 megabytes of raw data for each shot. Users will have the capability of controlling all analyzers, and analyzing hydrogen mass species for up to ten analysis pulse time regions for multiple plasma shots. These features make the Charge Exchange systems among the largest diagnostic applications software systems on TFTR.
