“…Although homogeneous gas ionization due to the ionization wave was emphasized in most works, some experimental observations demonstrated features of incomplete development of primary channels even at U U br . These features were observed with different gases, especially in long gaps [1,13,14]. The time interval required for primary channel formation we shall further name as channel formation time t f , by an analogy to a free gas breakdown approach [15].…”

An approximate model of multiple spark channel formation in a sliding gas discharge on a dielectric substrate surface is discussed. Each of the parallel sparks is treated as a constant-radius channel being quasi-static in space with a time-dependent resistance approximated by a falling function. The number of active channels as a function of discharge current is obtained empirically from the experiments being analysed. The spark model is then used for computer simulation of multiple spark formation in a conventional pulsed power supply source. The results of simulations for particular setups of earlier published works are shown to be in good agreement with the experimental data of these works.

“…The electrical breakdown is also accompanied by the inter-electrode voltage drop which is delayed with respect to the moment of application of the electrical field. Such a model has also been investigated in numerous works including those related to research concerning the use of extended, multi-channel and homogeneous surface discharges as powerful sources of UV and VUV radiation, as well as of low-inductance-operated multi-channel spark gaps in surface discharges [10][11][12][13][14][15][16][17][18][19][20]. Let us henceforth refer to this model as the 'surface breakdown model'.…”

Two models of the initiation of gas discharges in a transverse discharge lamp are compared and contrasted in this paper; the volume and near-surface breakdown models. Particular consideration is given to the breakdown voltage, the breakdown formation time interval and the extent of the initial gas ionization. Experimental measurements of the breakdown parameters for Xe both in the static and in the pulsed mode of operation are given and the predictions of the two models are compared against these results. It is concluded that the near-surface gas-breakdown model is appropriate for the discharge lamps under consideration.
