Query: 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(LVPD). The region satisfy
conditions for ETG turbulence, i.e. threshold condition, $ \eta_e = L_{n_e} /
L_{T_e} > 2/3 $ , where density scale length, $ L_{n_e} \sim 300 cm $ and
temerature scale length, $ L_{T_e} \sim 50cm $[S.K. Mattoo et al., Phys. Rev.
Lett., 108, 255007(2012)\cite{Mattoo_PRL}]. The measured flux is dominantly
electrostatic ($\Gamma_{es} \approx 10^{5} \Gamma_{em}$) although the nature of
the measured turbulence is electromagnetic($\beta \approx 0.6 $). The
turbulence has been established as a consequence of electron temperature
gradient (ETG) driven modes. Experimental observations of phase angle between
density ($ n_e $) and potential ($\phi $) fluctuations, $ \theta_{\tilde{n}_e,
\tilde{\phi}} $ and electrostatic particle flux, $ \Gamma_{es} $ shows good
agreement with the corresponding theoretical estimates for ETG turbulence.
