“…Для Nd:YLF-лазера энергия импульсов составляет до 2 J при длительности импульса 3 ns с частотой следования импульсов до 50 Hz. Для регистрации сигналов рассеяния применялась система фильтровых спектрометров, оснащенная прецизионной системой регистрации [10,11]. Особенностью диагностической системы является возможность регулировки временной задержки между лазерными импульсами Nd:YAG-и Nd:YLF-лазеров, обеспечивающей синхронизацию лазерных импульсов с наносекундной точностью.…”

Diagnostics of the plasma electron component by the method of Thomson scattering (TS) of laser radiation makes it possible to reliably measure the spatial distributions of the electron temperature and density. One of the obstacles to the implementation of TS diagnostics in thermonuclear reactors is the distortion of the spectral characteristics of the optical system due to radiation-induced absorption and contamination of optical elements with erosion products of the first wall. As a consequence, the reliability of measurements by the TS method will decrease over time. The paper describes the method of multi-laser Thomson scattering, which will solve this problem. The results of the first experiments on the Globus-M2 tokamak are also presented.
