Paschen’s curve

Simulation without field emission Experimental results Paschen s curve in atmospheric air... 

For dry air the Paschen s curve has a minimum at pd =6.65mbar.mm corresponding to a breakdown voltage of 360V (Schaffert R.). If the air gap field creates a voltage less than the breakdown voltage for the particular discharges will not occur in the gap. When the...

Experimental studies of the electrocapillary curve are very numerous. Besides Lippmann, Paschen,1 Rothmund,2 S. W. J. Smith,8 Gouy,4 Frum-kin,5 Koenig,6 Butler, Ockrent, and others,7 Hansen and Williams,8 and many others have published results. By far the most comprehensive studies are still those of Gouy. A few of the more typical of his results are reproduced in Fig. 54.
