Observation of radially inward turbulent particle flux in ETG dominated plasma of LVPD
Radially inward turbulent particle flux is observed in the core region of target plasma of
Large Volume Plasma Device where electron temperature gradient (ETG) driven turbulence
conditions are satisfied with threshold, η ETG= L n/LT> 2/3 [Mattoo et al., Phys. Rev. Lett.
108, 255007 (2012)]. The observed mode satisfies the scale length and frequency ordering
of ETG ( k⊥ ρ e≤ 1≪ k⊥ ρ i, Ω i< ω≪ Ω e), where k⊥ is the perpendicular wave vector,
ρ e, ρ i are Larmor radii of electron and ion, respectively, and Ω i, Ω e, and ω are the ion …
