No trend with density is observed in the small density range covered. Physics. devoted to applications such as fusion plasmas, and spe- cialized models such of the plasma beta. The total toroidal flux, Φtotal, of the equilibrium with vanishing plasma beta (no plasma pres-. No significant differences emerge from this analysis. January Page 4. beta
