Der Einfluß einer zylindrisch konvergierenden Stoßwelle auf ein Funkenplasma

The influence of a cylindrically converging shock wave on a spark plasma is investigated. The shock wave is produced by a spark discharge in the axis of a cylindrical vessel. After the reflection at the wall the shock wave returns to the spark channel. The results of time resolved spectroscopic studies of the plasma state are compared with calculations on the basis of a gas-dynamic model. The influences of possible deviations from thermodynamic equilibrium are critically discussed.
