description: The paper outlines the general physical principles of controlled nuclear fusion. The description of the main structural units of the most promising type of magnetic plasma confinement facilities - tokamaks is given. The definition of spherical tokamaks is formulated, their main differences from traditional tokamaks are described, and their main advantages and disadvantages are presented. A review of the largest of the modern spherical tokamaks is made, and their modernization is described. The concept of a dispersive interferometer (DI) for measuring plasma electron density has been introduced, a schematic diagram of DI, a phase modulation method and an algorithm for reconstructing a phase from an interference signal and then calculating the linear-integrated electron density has been described. An optical DI scheme installed on the Globus-M2 spherical tokamak is given and described. Also, the specifics and goals of installing a CO2-laser-based DI on a Globus-M2 tokamak are given.
