Anomalous Behaviour

The positive column of a low pressure stationary gas discharge in a longitudinal magnetic field is investigated. Above a critical magnetic field the charged particle losses of the discharge increase rapidly in contradiction to the diffusion theory of the positive column. This effect has become known as LEHNERT-effect. Different theories and hypothesis are investigated and compared with the experiments to explain this phenomenon. It is shown that all experiments are most compatible with a theory of KADOMTSEV which states the anomalous behaviour of the positive column to be a turbulence like instability.
