PULSE DISCHARGE IN DENSE PLASMAS (in German)
Journal Article

· Annalen der Physik (Leipzig)
A summary representation is given of investigations on ohmic heating. Experimentally a high current pulse dischange over a gas-vortex-stabilized, high- temperature arc in nitrogen and hydrogen atmospheres was the basis. The theory treats the problems in a channel model corresponding to the study. The transfer of the energy obtained in the electric field to random motion as a result of scattering processes was studied, considering possible energy losses. In the case of nitrogen, the heating at a temperature of approximately 85,000 deg K was almost compensated by the loss mechanism, here chiefiy radiation. The losses lead to a channel broadening because of radiation transport. In the case of hydrogen pulses, the heating is limited because the plasma channel is unstable. The maximum temperature to be expected is about 300,000 deg K at atmospheric pressure and about 500,000 deg K at 10 atm. The diagnostic method used in the evaluation of the discharge phenomena was described briefly. (tr-auth)
