Abstract
Plasma parameters of carbon arcs in vacuum have been measured with high temporal and spatial resolution (1 ¿s and 10 ¿m, respectively). Near the surface the electron temperature was ¿1 eV. It increased to values of about 10 eV for distances > 10 mm by anomalous heating due to ion sound turbulence. The average electron density varies with the distance r as r-2. Values of about 1025 m-3 have been found at r = 15 ¿m.
