Messungen der radialen Verteilung der elektrischen Feldstärke im Wasserstofflichtbogen mit axialem Magnetfeld
Keyword(s):
Abstract In a stationary hydrogen arc with axial magnetic field the radial distribution of the axial electric field Ez was measured by shooting a double potential probe across the arc. It was found that Ez strongly decreases outside the magnetic flux tube defined by the cathode radius and tends to zero. The measured distribution of Ez agrees qualitatively with computations allowing for the observed rotation profile. In a very fast rotating arc with a hollow anode Ez was found to vanish not only outwards, but also towards the axis, as predicted by the theory.
