During edge localized modes (ELMs), filaments are expelled from the edge of H-mode plasmas
[1]. Shear flows have been shown to be an important ingredient, and are now included in the
models [2]. It is therefore essential to investigate experimentally the dynamics of the filaments
during an ELM crash. In this contribution, the observation by Doppler reflectometry (DR) of an
acceleration, followed by a reversal of the filament velocity during type-I ELMs is reported.
