Control System for Dispersion Interferometer on Globus-M2 Tokamak

This paper describes the control system for a dispersion interferometer based on a CO2 laser developed by the Budker Institute of Nuclear Physics (Novosibirsk, Russia) for the Globus-M2 tokamak (Ioffe Institute, St. Petersburg, Russia). The basis of this system is the programmable controller ADAM-5510E/TCP with a set of analog and digital input/output modules and specially developed software that allows monitoring and control of the operation and parameters of interferometer elements. During the year of the dispersion interferometer operation as a standard diagnostic at the Globus-M2 tokamak, the control system showed good levels of reliability and sustainability.
