Initial confinement studies of ohmically heated plasmas in the tokamak fusion test reactor
Initial operation of the tokamak fusion test reactor has concentrated upon confinement studies of ohmically heated hydrogen and deuterium plasmas. Total energy confinement times (tau/sub E/) are 0.1--0.2 s for a line-average density range (n-bar/sub e/) of (1--2.5) x 10/sup 19/ m/sup -3/ with electr...

Zusammenfassung: | Initial operation of the tokamak fusion test reactor has concentrated upon confinement studies of ohmically heated hydrogen and deuterium plasmas. Total energy confinement times (tau/sub E/) are 0.1--0.2 s for a line-average density range (n-bar/sub e/) of (1--2.5) x 10/sup 19/ m/sup -3/ with electron temperatures of T/sub e/(o)approx.1.2--2.2 keV, ion temperatures of T/sub i/(0)approx.0.9--1.5 keV, and Z/sub eff/approx.3. A comparison of Princeton large torus, poloidal divertor experiment, and tokamak fusion test reactor plasma confinement supports a dimension-cubed scaling law. |
