Anomalous vortex electron fluxes produced as a result of inverse bremsstrahlung of an rf field
Ovchinnikov K. N. , Silin V. P. , Uryupin S. A.
The nonlocal vortex current and the nonlocal vortex heat flux of electrons in a plasma heated by inverse bremsstrahlung of an rf field are derived. The magnitudes of the fluxes are established for all possible values of the ratio of the length scale of the variations in the amplitude of the electromagnetic field, ~\lk, to the mean free path of a thermal electron, /. As the parameter kl increases, the vortex current initially reaches a maximum jl at £/«=0.02 and then falls off, changing the sign of the helicity at £/^0.05. At kl^0.9, the absolute value of the current reaches an anomalously high value jj^^h and men fau<s °ff mono-tonically. © 1995 American Institute of Physics.
