Radial Electric Fields during L-to-H Transition and Edge-Localized Modes from Charge-Exchange Diagnostics of Ripple-Trapped Particles
Neutral fluxes from charge exchange processes with ripple trapped particles depend on radial electric fields. Their time behavior during low confinement (L) to high confinement (H) transition and edge localized modes (ELMs) was studied with a time resolution of up to 50 ms. 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 completely detached H (CDH) mode.
