Possibility of quasicontinuous measurement of the evolution of the electron temperature of a plasma by the Thomson scattering method

A method is proposed for increasing the frequency of Thomson scattering measurements of the electron temperature of a plasma to 100 kHz. The approach makes it possible to raise the diagnostic sensitivity under stationary discharge conditions by three orders of magnitude. The possibilities of the method are confirmed experimentally.
