Modulation instability in pulsed surface-wave sustained discharges

Travelling-wave-sustained discharges

“…In more detailed experiments [39] showing the simultaneous self-consistent changes along the discharge length of the plasma-density pulses and the electric field-power, effects like a separation of a solitary-like wave from the leading edge of the pulse have also been observed.…”

“…With discharge length L fixed to be the same, the end of the argon discharge is extended towards lower density values especially in the case of the low ( ea / )-value (Figs. 39 and 41a) of the microwave discharge. The position of the end of the 2.45 GHz argon discharge indicates that the very end part of the discharge (the one corresponding to the extended drop of the plasma density in Fig.…”

“…The studies in the literature of pulsed regime operation of waveguide discharges are on discharge maintenance without external magnetic field, i.e. with SWs as carrier waves of the pulses [13,33,39,40,130,[158][159][160][161][162][163][164][165]325,326]. Possibilities for creating high density plasmas with intensive spectral line emission at low averaged power applied for the discharge production have been outlined as reasons motivating the early studies on pulsed SWSDs.…”

“…The data accumulated in the experiments [13,39,40,[158][159][160][161][162][163][164]325] on the pulsed regime operation of the SWSDs are mainly for the ionization front velocity, the rise time of the pulse and the axial profiles of the plasma density. In more detailed experiments [39] showing the simultaneous self-consistent changes along the discharge length of the plasma-density pulses and the electric field-power, effects like a separation of a solitary-like wave from the leading edge of the pulse have also been observed.…”

“…[39][40][41][42][43][44][45][46]) which motivate aspects of the reported modelling are also pointed out in the review.…”
