Mechanisms of H2 vibrational excitation and H− generation in a low-voltage plasma-beam cesium-hydrogen discharge

Volume Production of High Negative Hydrogen Ion Density in Low-Voltage Cesium-Hydrogen Discharge

“…In this case, the main mechanism of thermal electron heating is a collisional damping of Langmuir waves excited in plasma by means of plasma-beam instability. Because of this mechanism, a significant part of initial beam energy is transferred to thermal electrons [14,18].…”

“…Experimental investigation of LV cesium-hydrogen discharge was performed in [14,[19][20][21][22][23][24]. In the initial experimental works (e.g.…”

“…In the initial experimental works (e.g. see [14,[19][20][21]) the probe method of plasma diagnostics was developed and local parameters (n e , T e , ϕ) were measured. It was shown experimentally that all the plasma parameters, which are needed for intensive H -generation, were really obtained in the discharge plasma.…”

“…In particular, just in the first experimental works (e.g. see [14,[19][20][21]), it was shown that high electron concentration n e and optimum electron temperature T e for H -generation by means of DA were really achieved in the discharge plasma.…”

An investigation of low-voltage beam discharge in helium. I. Experiment

“…Low-voltage discharges in vapours of alkaline metals have been investigated in detail (Baksht et a1 1978). It has been shown that the physics of such discharge is governed by relaxation processes of electron beams in the discharge plasma (Djuzhev et al 1972, Baksht et al 198 I , 1984, 1990.…”
