Behavior of an arc discharge in a forevacuum plasma source of electrons

Fuzzy simulation system for finding optimal current densities in the electron beam of a forevacuum plasma source

“…The radial coordinate r was measured from the symmetry axis of the electron source (from -60 to 60 mm), which coincided with the center of the cathode, while the vertical coordinate L was measured from the extractor (75-275 mm) [1].…”

“…However, the nonuniform distribution of the current density along the cross section of the electron beam results in the nonuniform processing of the material surface [1,2]. The uniform distribution of the current density is attained by optimizing the parameters of the forevacuum plasma source.…”

Generation of large cross-sectional area electron beams by a fore-vacuum-pressure plasma electron source based on the arc discharge

“…Operation of the arc discharge in the fore-vacuum plasma electron sources has a series of distinctive features associated with the effect of the residual gas ionization on the arc parameters. Study of arc initiation and arc discharge features in the plasma electron source operating in the fore-vacuum pressure range can be found in our earlier papers [9,10].…”
