Development of a software facility for joint operations with experimental data on thermonuclear fusion, including software for information interaction and software for analysis and display of experimental data, is presented. The architecture, functionality, and concepts of constructing a graphical user interface were determined; the technological approach to their implementation was justified, and technological solutions were selected and tested. The considered solutions support remote participation in scientific experiments and operations with their results. Conclusions based on the results of the work carried out are formulated, and plans for the further development of the software facility are presented.
