The Dynamic Stark-Effect in a Turbulent Hydrogen Plasma

Abstract
The profiles of the first three Balmer lines of hydrogen are measured in a turbulent heating experiment. From the position of Stark satellites the field strength of low frequency oscillations (ω ~ ωpi) is calculated. The energy density in these electrostatic oscillations can amount to 1% of the therm al energy. The presence of high frequency oscillations (ω ~ ωpe) is concluded from satellites near ± ωpe from the unperturbed line position.
