Experimental evidence of self-regulation of fluctuations by time-varying flows.

Physical Review Letters, vol.88, no.4, 28 Jan. 2002, pp.045001/1-4. Publisher: APS, USA.

Abstract
We report the first extended experimental results indicating that radially localized time-varying potential structures, which possess many of the characteristics of zonal flows, are generated by strong fluctuations. Experiments performed in the H-1 heliac show that these poloidally symmetric flows are nonlinearly coupled to other fluctuations and are responsible for significant modifications in fluctuations and in the fluctuation-driven transport.
