Time-space properties of the global potential oscillation, which is ascribed to the low frequency zonal flows, have been investigated in two plasmas produced by ECRH and NBI heating schemes that are characterized by different mean radial electric field structures. | |||
The width of the oscillating structure strongly depends on the heating scheme <ref>T Kobayashi, U Losada, B Liu et al., Nuclear Fusion (2019) in press</ref>. Preliminary results roughly suggest that the radial width of LRC increases with the ion mass in NBI scenarios <ref>U Losada PhD Thesis (2019)</ref>. Those results show, for the first time and with unprecedented detail, how sensitive are the properties of zonal flows to plasma conditions, providing a key experimental guidance for model validation. | The width of the oscillating structure strongly depends on the heating scheme <ref>T Kobayashi, U Losada, B Liu et al., Nuclear Fusion (2019) in press</ref>.

To goal of this proposal is to expand the existing database of the width of zonal flows with emphasis on the isotope mass effect. | To goal of this proposal is to expand the existing database of the width of zonal flows with emphasis on the isotope mass effect. | ||
