Development of a graphical software package to analyze Alvand Tokamak experimental Data

Abstract

The data acquisition system of the Alvand tokamak is a very old system of 32 channels. The data capacity of each channel is 2 kilobytes, altogether 64 kilobytes, which store the experimental data of selected channels in binary format. The most important deficiency of this system is the use of the CGA graphic adapter resolution of pixels of 4 bits in-depth. By considering the old graphical user interface, this deficiency has made displaying the experimental data in more detail impossible. Due to the old software used to display the experimental data, updating to an appropriate graphical environment, that can display the data on a typical modern computer at this laboratory, is necessary. For this purpose, a software package was developed to speed up the data analysis of experiments. The core of this package includes 400 lines and the graphical user interface consists of 3000 lines of Matlab code.
