Description of the activity, including motivation/objectives and experience of the proponent (typically one-two pages)

Results reported in the TJ-II plasma edge region has shown, with unprecedented detail, how sensitive are the properties of zonal flows to plasma conditions providing key experimental guidance for model validation .

Whether this sensitive is due to the magnitude / sign of radial neoclassical electric fields affecting Reynolds stress driven ZFs, neoclassical mechanisms, plasma collisionality or / and fast particle effects remain an open question.

If applicable, International or National funding project or entity
