It has been shown that the intermittence can be fruitfully exploited in the framework of fusion plasma physics: namely, it is found to decrease at locations where a single (helical, MHD) mode dominates, thus allowing to study the relation between turbulence and helical modes, and it was found to be affected by plasma flows (such as zonal flows) <ref>B.
