Abstract :
Compact toroid (CT) injection experiments have been carried out in JFT-2M for the understanding of the physics of CT injection as means of tokamak fueling. An increase in the line averaged electron density Δne≈0.4×1019 m−3 was obtained in the case of a CT velocity of 300 km/s and a toroidal magnetic field of 0.8 T. The fueling efficiency is roughly 40%. An asymmetric radial profile with a peripheral second peak in the soft X-ray emission was produced for ∼0.4 ms by this CT injection and resulting in a tokamak disruption.
