Popis:	The influence of afterglow period τ, voltage increase rate k, and electrode gap d on breakdown voltage Ub for a nitrogen-filled tube with spherical electrodes of diameter D⪢d and p=6.5mbar has been investigated. The data for the breakdown voltage were obtained for the case when there is a presence of N(S4) atoms, which release secondary electrons via recombination on the cathode. By fitting the experimental data of breakdown voltage mean values as a function of the voltage increase rate, the static breakdown voltages for afterglow periods of 15 and 100 s were estimated. The electrical field as a function of the electrode gap using breakdown voltage mean values was also determined. It is shown that experimental results of the breakdown voltage mean value as a function of pd in the interval of d from 0.82 to 1.62 mm can be very well described with Paschen’s law, valid for the case of parallel-plate electrodes.
