A resonance gas desorption as an initiating factor of the vacuum insulation damage

Studies of charged particle emission connected with resonance gas desorption are of great importance for understanding of processes providing both pre-breakdown conductivity of a vacuum gap and probable formation and sustaining of vacuum arc (vacuum breakdown). For operational high voltage electrodes such currents may be rather negligible thanks to low numbers of defects such as pores on their surfaces. This paper presents some results of experiments conducted for special porous electrodes
