摘要：

Neutral fluxes from charge-exchange processes with ripple-trapped particles depend on radial electric fields. Their time behavior during L-to-H transition and edge-localized modes (ELMs) was studied with a time resolution of up to 50 mu s. No jumps at the L-to-H transition are observed that are faster than the increase of the field after ELMs. The signature of the neutral particle spectra is different for L and H modes and allows discrimination of the modes. ELMs and electric fields are present during the CDH (completely detached H) mode.
