摘要：

A study of the evolution of the filaments observed during Type I ELMs on ASDEX Upgrade and MAST is presented. The filaments start off rotating toroidally/poloidally with velocities close to that of the pedestal. This velocity then decreases as the filaments propagate radially. On both devices the ion saturation current e-folding lengths of the filaments show a weak, if any, dependence on the size of the ELM (Delta W-ELM/W-ped). On MAST the measured radial velocities of the filaments also show at most a weak dependence on Delta W-ELM/W-ped.
