Pellet fueling of JET plasmas during ohmic, ICRF and NBI heating

Creators

Description

Pellet fueling experiments have been performed on JET using a single-shot pneumatic injector giving 4.6mm (4.5 x 1021 D atoms) and 3.6mm (2.2 x 1021 D atoms) diameter cylindrical deuterium pellets with velocity 0.8 ≤ V(km.s-1) ≤ 1.2. Z/sub eff/ < 1.5 with n/sub D//n/sub e/ ∼ 1 on axis has been achieved. In configurations with a magnetic seperatrix, peaked electron density profiles with n/sub e/(o)/anti n/sub e/ ∼ 2 are obtained, with n/sub e/(0) ≅ 1.2 x 1020m-3 and T/sub e/(0) ≅ 1keV. Separately, high value of n/sub D/(0)tau/sub E/T/sub i/(0) = 1.3 x 1020m-3.s.keV at T/sub i/90) = 6.5keV has been obtained with pellet fueling followed by NBI heating
