Abstract
The control of the density profile during the initial plasma current rise is a critical issue to optimize ohmic and fusion heating rates of Ignitor plasmas. Simulations performed with the NGS ablation model, for the reference ignition plasma parameters (n e0 ≅ n i0 ≅ 10 21 m −3 , T e0 ≅ T i0 ≅ 11 keV), indicate that deuterium pellets of a few mm (≤ 4 mm) in size injected at 3–4 km/s from the low field side should ensure adequate deep fuelling.
