Notes:
The MIT data-acquisition and physics analysis system was designed to provide high throughput and ready access to data from any run. The system is based on a VAX 11/750 which is to be configured in a VAX cluster back-end network. The front end for the data system is a kinetic system CAMAC serial highway interface. Preexisting software packages have been combined into a coherent system which has required a minimum of new software development. The acquisition, archiving, basic analysis, and display of 1.5 Mbyte of data for every shot is accomplished once every 5–8 minutes with any shot being easily reanalyzed. A set of standard tools is provided for use in user-written programs several of which are incorporated into the production system. The range of interactive analysis options is illustrated by using the medium-energy x-ray diagnostic in one anchor as an example. The resulting physics analysis includes intercomparison with other diagnostics to compute Te, the fraction of hot electrons, and other plasma parameters.
