Peculiarities of plasma fluctuations during RF heating in Uragan-3M torsatron by means of two alfven waves
Three wave interaction has been observed in experiments on Uragan-3M torsatron. Two RF antennas with frequencies Ω1 and Ω2 were used simultaneously for plasma production and heating. Plasma was probed by microwaves, these allowed to study reflection of microwaves at almost whole plasma radius. Spect...

Мікрохвильове зондування є корисним засобом для вивчення їх впливу на поведінку плазми та, можливо, для відтворення профілю поглинання ВЧ потужності. Трехволновое взаимодействие наблюдалось в экспериментах на торсатроне Ураган-3М. Две ВЧ антенны с частотами Ω1 и Ω2 одновременно использовались для создания и нагрева плазмы, которая зондировалась микроволнами, место отражения которых перекрывало почти весь радиус. При спектральном анализе отраженных СВЧ сигналов обнаружены флуктуации плотности плазмы с частотой Ω1 – Ω2. При появлении колебаний на частоте Ω1 – Ω2 наблюдалось подавление НЧ флуктуаций. Микроволновое зондирование является полезным средством для изучения их влияния на поведение плазмы и, возможно, для воссоздания профиля поглощения ВЧ мощности. 2005 Article Peculiarities of plasma fluctuations during RF heating in Uragan-3M torsatron by means of two alfven waves / O.S.
