The penetration of deuterium pellets into ohmically heated TORE SUPRA plasmas has been studied for various plasma conditions (ne = 1 × 1019-6 × 1019 m3, Te = 1-4 keV) and pellet characteristics (Np = 2 × 1020-1.3 × 1021 atoms/pellet, Vp = 0.6-2.4

The largest striations in Hα(Dα) light observed across the ablation cloud of injected hydrogen pellets can be explained in most cases by the presence of resonant magnetic surfaces. The authors suggest that it is possible to identify these striation

Two-dimensional intensity distribution mappings of photographs of pellet ablation cloud trajectories in TFR and TORE SUPRA reveal irregular shapes of the luminous striations. The observed features are not well understood, but a likely interpretation
