Abstract
The operational interface to the DIII-D neutral beam system
consisted of several interactive devices that the operator used to
sequence neutral beam conditioning and plasma heating shots. Combined
with an ongoing effort to increase the degree of automated operation and
its reliability, a single microcomputer-based interface for each of the
four neutral beam MODCOMP Classic control computers was developed,
effectively replacing some twenty pieces of hardware. Macintosh II
microcomputers were selected, with 1 MB RAM and off-the-shelf
input/output (I/O) consisting of a mouse, serial ports, and two
monochrome high-resolution video monitors. The software is written in
Pascal and adopts standard Macintosh window techniques. From the
Macintosh interface to the MODCOMP Classic, the operator can control the
power-supply setpoints, adjust ion source timing and synchronization,
call up waveform displays on the Grinnell color display system, view the
sequencing of procedures to ready a neutral beam shot, and add operator
comments to an automated shot-logging system. The Macintosh interface
also provides a springboard for increased levels of automation of the
neutral beam control system, within the framework of a cost-effective
and standardized software environment
