Abstract

Cryogenic pellet injection has been used in START and it is under commissioning for MAST for fuelling and diagnostics. In START NBI, heated plasmas fuelled with deuterium pellets, high normalized density (Greenwald number N_G≤1.1) with good energy confinement time (τ_E/τ_E(elmf) ^ITER97≤1.3) both at high beta (β_T≤25%, β_N≤4.9) have been obtained for time scales close to the energy confinement time (∼ τ_E). In addition, high fuelling efficiency (∼ 100%) have also been simultaneously observed. A complete pellet injection programme is currently under development in MAST, including the commissioning of a eight pellet injector, technical aspects of launching pellets through guide tubes, dedicated diagnostics, and modelling.

Funding

This work is jointly funded by the UK Department of Trade and Industry and EURATOM. ENEA-Frascati supplied the single pellet injector, FOM the multi-pellet injector, and the ‘PELLET’ code and the NBI equipment (on loan) are from Oak Ridge National Laboratory (ORNL) and US DOE. EFIT was provided by General Atomics (GA).
