E-beam spreading and resulting field variations in CO2 laser plasmas

Plasma parameter bi-stability in e-beam sustained discharge in Xe

“…As was already mentioned, the production rate of secondary electrons in the gas is determined by parameters of the fast electron beam. The magnitude of q was estimated using semi-empirical formulae presented in [27]. According to our evaluation, the production rate of secondary electrons q = 10 16 cm −3 s −1 is provided by the e-beam current density j b ≈ 2 µA cm −2 .…”
