Diagnostic of plasma density fluctuations by collective scattering of 2 mm radiation

Summary form only given, as follows. Description of the experimental scheme for measurements of plasma density fluctuations in L-2 stellarator using the collective scattering of 2 mm radiation is presented. Scheme allows to obtain spectra S(/spl alpha/,k) for three values of k Simultaneously and to investigate the spectra dynamics during one stelldrator discharge.
