The effect of the cathode material on the delay time is studied. A test for optimality for the gap electrode surface condition is stated. When prepared under optimal conditions, cathodes have a minimum field enhancement coefficient at surface microirregularities. This allows one to estimate the emission parameters of the cathode surface and the dielectric strength of vacuum insulation. © 2003 MAIK “Nauka / Interperiodica”.SubjectsELECTRIC breakdown; VACUUM; CATHODES; THERMODYNAMICSPublicationTechnical Physics, 2003, Vol 48, Issue 9, p1192ISSN1063-7842Publication typeArticleDOI10.1134/1.1611907
