N2 - The article is devoted to the description of plasma density diagnostics in the Globus-M2 tokamak (St. Petersburg, Russia) based on a dispersion interferometer (DI) using a CO2 laser as a source of probing radiation. The paper presents a description of the DI optical scheme and the results of its first tests, which revealed the need to modernize the optical and measuring paths. The new elements of the DI and the results obtained as part of his regular work on the Globe-M2 tokamak are described. DI is a full-fledged part of the Globus-M2 diagnostic complex and makes it possible to obtain real-time reliable data of the plasma electron density absolute value in all operating modes of the tokamak. The range of the noise component during linear density measurements does not exceed min ≈ 6·1016 m– 2 with a time resolution of 20 µs. The relative error in calculating of the linear density absolute value does not exceed 2.5%.
