Dependence of confinement on plasma ion species in JETFunded under: FP2-FUSION 10C
The properties of JET plasmas obtained in similar conditions, but using different ion species, are compared. In hydrogenic limiter discharges with NBI heating, particle confinement and sawtooth activity display a strong isotopic dependence. However, the improvement in global energy confinement from hydrogen to deuterium is only approximately 20 %, not consistent with the square-root dependence of tau(E) on A(i) often found in L-mode scaling relationships. No significant change in energy or particle confinement is observed when deuterium is replaced by helium-3.
