Energy confinement in the TM-G tokamak at high plasma densities
Stefanovskii A. M.
It is concluded from an analysis of experimental data obtained from the TM-G and other tokamaks that the dependence rE(ne) reaches saturation at high densities because of a contraction of the current channel and a disruption of the "self-consistent" current profile. Another important factor may be the excitation of drift waves at densities near the Murakami limit.
