Escaping electrons and parametric instability in the Uragan-3M torsatron

Electromagnetic fluctuation spectra in the peripheral area of the Uragan-3M trap and plasma density fluctuation spectra in the plasma confinement zone have been compared with the modulation spectra of escaping electron flux. The dependence of the form of fluctuation spectra on the escaping electron flux intensity has been studied. Plasma confinement and heating conditions in the Uragan-3M torsatron have been discussed.
