Volume charge density and radial electric field E r (r) in a moving tokamak plasma

Radial Electric Field in Tokamak Plasmas as a Physical Consequence of Ehrenfest’s Paradox

“…Below we present important quantitative and qualitative correlations of theoretical results (using Equations (6), (9) and (10)) with tokamak experimental data [20,[36][37][38][39][40][41][42].…”

“…Consideration of such dependence for the purpose of calculation of tokamak plasma charge density is shown in [19,20] …”

“…The first important conclusion from Equation (10): if is not close to zero in the plasma core then a toroidal ion beam is created in that region (its velocity logarithmically tending to infinity [20,23]). So, we have to suppose that     It is possible to derive Equation (11) from Equation (9) directly, see [19].…”

“…Recently, in [19,20] the effect of relativistic contraction of an "electron ring" circumference in steady state tokamak plasma rotating in toroidal direction with current velocity e has been analyzed. Let be the minor radius of a tokamak magnetic surface, see Figure 1.…”

“…The diffusion (convention) term can be determined within the frame of different approaches, see [20]. …”
