Displaying DIII-D plasma data using DEC's X window system

PDF Version Also Available for Download.

Description

The D3-D tokamak program, funded by the Department of Energy, carries out plasma physics and fusion energy research experiments. The machine began operation in February 1986; at that time, approximately 7 Mbytes of data was collected for shot. Since that time, the shot size has steadily increased to over 50 Mbytes with the average shot size between 35 and 45 Mbytes. Shots are fired every 12 to 15 minutes and last approximately 5 to 10 seconds. Between 30 and 40 shots are fired each day when plasma experiments are scheduled. In 1987 MFITD and MFITPLAY were written/modified. These two programs ... continued below

Description

The D3-D tokamak program, funded by the Department of Energy, carries out plasma physics and fusion energy research experiments. The machine began operation in February 1986; at that time, approximately 7 Mbytes of data was collected for shot. Since that time, the shot size has steadily increased to over 50 Mbytes with the average shot size between 35 and 45 Mbytes. Shots are fired every 12 to 15 minutes and last approximately 5 to 10 seconds. Between 30 and 40 shots are fired each day when plasma experiments are scheduled. In 1987 MFITD and MFITPLAY were written/modified. These two programs provide graphical output that allows the users to see, before the next shot, the plasma shape and the locations of the plasma and magnetic flux lines within the tokamak. MFITD performs the computations which calculate the shape and location of the plasma; it also graphically displays a small subset of timeslice data. MFITPLAY graphically displays the full set of timeslice data. Through interactive commands, MFITPLAY also allows the user to control the various aspects of how the data is displayed. In 1990, both programs were converted from User Interface Services (UIS) routines, which are part of the MicroVMS workstation graphics software, to DEC's X Window System using the DECWindows window manager. These modifications were required because of a move by Digital Equipment Corporation (DEC) to support X windows and phase out UIS. Due to the nature and purpose of each program, MFITD needed only simple graphics conversion while MFITPLAY was completely rewritten. The DECWindows version of MFITPLAY offers a number of improvements, such as a more intuitive user interface.
