Pellet fuelling of JET plasmas during ohmic, ICRF and NBI heating
- 1. Commission of the European Communities, Abingdon (UK). JET Joint Undertaking
Description
Pellet fuelling experiments have been performed on JET using a single-shot pneumatic injector giving 4.6 mm (4.5x1021 D atoms) and 3.6 mm (2.2x1021 D atoms) diameter cylindrical deuterium pellets with velocity 0.8 ≤ V(km·s-1) ≤ 1.2. Zeff < 1.5 with nD/ne ∼ 1 on axis has been achieved. In configurations with a magnetic separatrix, peaked electron density profiles with ne (O)/n-bare ∼ 2 are obtained, with ne (O) approx.= 1.2x1020m-3 and Te (O) ∼ 1 keV. Separately a high value of nD (O)τETi=1.3x1020m-3·s·keV at Ti (O) = 6.5 keV has been obtained with pellet fuelling followed by NBI heating. (author). 12 refs, 5 figs
