Abstract

In a gas discharge device having a gas discharge channel, which comprises two gas discharge electrodes and a gas discharge volume lying between said electrodes, having an energy storage circuit connected by a switching device to the gas discharge electrodes for producing a current surge flowing between a first output terminal and a second output terminal for operating a gas discharge, and having an ignition device for separate ignition of the gas discharge, in order to improve said device in such a way that it operates better and more reliably, it is proposed that the switching device comprises a voltage divider lying between the output terminals and comprising a first and a second impedance, that the gas discharge electrodes are connected in parallel to the first impedance and a spark gap is connected in parallel to the second impedance, that the first impedance is so dimensioned that, in the absence of a gas discharge, a voltage lying below the breakdown voltage of the gas discharge electrodes is applied to the latter, and that the spark gap is so designed that its breakdown voltage is exceeded after separate ignition of the gas discharge and so the current surge flows from the e…
