Abstract
Electrostatic potential measurements in a fully ionized laboratory plasma containing strong ion cyclotron wave turbulence are reported. The waves are excited by drawing electron current aligned with the external magnetic field in a localized channel whose dimension perpendicular to the magnetic field is of the order of the hot ion Larmor radius. The waves are found to modify the plasma properties. They heat the plasma ions and, because of their large amplitude, modify the electron distribution function. The waves stimulate the generation of energetic electrons of at least 10 times the thermal energy. Although the classical conductivity along the magnetic field is extremely large, the turbulent plasma is shown to be able to support a weak electric field parallel to the magnetic field.
