The paper presents some results of measurements on shock tubes with electrodes in the form of parallel conductors. It deals primarily with the shape of plasma moving in the said tube, the dependence of the plasma velocity on the pressure of air, helium and hydrogen filling the tube; further, it gives the results of measurements of the dependence of the plasma velocity on the distance from the discharge origin and on the voltage across the condenser battery.

The author believes that the experimental results given in this paper could be of use for certain theoretical discussions of plasma behaviour in shock tubes with parallel conductors, as well as for an eventual plasma acceleration by means of an external magnetic field. Finally, he wishes to express his thanks to Ing. J. Hyneček and the staff of the Physics Department for their unselfish assistance in the construction of the apparatus.
