description: In this paper, the volt-ampere characteristics of a DC discharge in caesium vapor were researched. For the research, an experimental method was developed based on the observation of evolution of near-electrode regions, and the registration of volt-ampere characteristics of the discharge. In accordance with the experimental method, an experimental setup was developed. A gas-discharge lamp filled with a mixture of Xe + Cs gases was used as a burner. In the initial state, the xenon pressure in the burner is PXe â 20 Torr, the pressure of the saturated caesium vapor at room temperature is PCs ~10-6 10-5 Torr. During a 10-minute warm-up, changes in the discharge behavior were recorded. Based on the obtained experiments, the features of the evolution of near-electrode regions and current transfer in them during the transition from a glow discharge to an arc discharge were considered. Conclusions are made on the topic of the physical nature of the transition of a glow discharge to an arc discharge. An assumption is made and justification is given for the possibility of photoemission as a determining factor in the transition of a glow discharge to an arc without the appearance of cathode spots. The results obtained allow us to hope for the possibility of implementing the transition from a glow discharge to an arc discharge in a short period of time without the appearance of cathode spots when switching on the lighting lamps of pulsed-periodic discharge, as well as special-purpose lamps, which will increase the service life of gas-discharge lamps.
