Abstract
Experimental data for breakdown delay time in vacuum, which are received in electric fields of various degree of heterogeneity for pulses of different shape and duration, are analyzed and generalized. The results, which are obtained at differ experimental conditions under optimum performances of pulsed conditioning, are given rise to the conditions of uniform field and rectangular pulse with duration, tp1=0.5 mus. The united dependences of breakdown voltage U br(d) and electric strength E0(d) on interelectrode distance are obtained. Taking into account full-voltage effect, the curves of UbT(d) and E0(d) were plotted in the range of gap spacing of 3middot10-3lesdles 2middot102 mm, which overlaps five orders of magnitude. It is shown that the electric strength rises and the breakdown voltage decreases in the ranges of 2.5middot107lesE0les7.5middot108 V/m and 5middot103 lesUbr les 2.5 kV with distance decrease from 20 cm down to 3 mum
