Neutral-injection-induced transport in mirror-confined plasmas

Plasma transport caused by ion/neutral atom collisions I. Slab model

“…An early paper on this subject [4] considered the effect of ion/neutral collisions on density buildup in neutral-beam-injected plasmas. Woo [5] discussed these processes in connection with sustenance conditions for neutral-beaminjected plasmas. Studies by Bekhtenev and Volosov [6] and by Bekhtenev et al [7] of rotating plasma reactors described some effects of ion/neutral collisions in such devices.…”

“…For a variety of reasons the previously published calculations [4][5][6][7][8][9] are not applicable to plasma/cold gas interaction. For example, Futch et al [4], who assumed large-orbit ions, did not derive local fluxes.…”

“…For example, Futch et al [4], who assumed large-orbit ions, did not derive local fluxes. Woo [5] and also Futch [9] calculated local fluxes, but assumed that the ion velocity was the same in magnitude as the neutral velocity. This, of course, is inappropriate for plasma/cold gas interactions.…”
