Abstract (en)
[origin: EP0963140A2] The method involves igniting a light arc between an anode and a cathode and using it to ionise a gas or vapour. The light arc is powered by voltage pulses, whereby the voltage applied to the anode-cathode path falls below the ignition voltage during the pauses between pulses so that the light arc is quenched in the pauses. An Independent claim is also included for an arrangement for implementing the method.
