Proposal title
Influence of edge radial electric fields on particle and heat transport in the SOL
Name and affiliation of proponent

Description of the activity
Turbulence radial spreading controlled by sheared ExB flows has been experimentally identified in TJ-II [1]. The gradual narrowing of the heat flux profile observed from L to I and to H-modes in AUG would be consistent with TJ-II picture [2].
The goal of this proposal is to investigate the influence of edge ExB sheraed flows on SOL particle & heat transport .
