Abstract: A study of the switching process of a short (1 mm) gas gap initiated by a spark discharge along the dielectric surface was carried out by the method of shadowgraphy with nanosecond time resolution. The presence of a shock wave propagating from the cathode spot and signs of intermediate accumulation of the invested energy in the form of excitation energy of gas molecules or turbulent gas flow were detected.

Keywords: shadowgraphy, gas discharge, shock waves, switch.
