Query: Observation of Electromagnetic Fluctuation Induced Particle Transport in
  ETG Dominated Large Laboratory Plasma   The Large Volume Plasma device(LVPD), a cylindrically shaped, linear plasma
device of dimension( $\phi =2m $, $ L =3m $) have successfully demonstrated the
excitation of Electron Temperature Gradient(ETG) turbulence[ Mattoo et
al.,[1]]. The observed ETG turbulence shows significant power between $\omega
\sim (25-90 krad/s )> \Omega_{ci}(= 8 krad/s )$, corresponding to the
wavenumber, $ k_y \rho_e ~ (0.1- 0.2)$ where, $ \Omega_{ci}$ and $\rho_e(=5 mm
) $, ion cyclotron frequency and electron Larmor radius, respectively. The
observed frequency and wave number matches well with theoretical estimates
corresponding to Whistler-ETG mode. We investigated electromagnetic (EM)
fluctuations induced plasma transport in high beta ( $ \beta \sim 0.01 - 0.4 $
) ETG mode suitable plasma in LVPD. The radial electromagnetic (EM) electron
(ion) flux ( $ \Gamma^{e,i}_{em} $) results primarily from the correlation
between fluctuations of parallel electron current ($\delta J_{\parallel ,e,i}$
) and radial magnetic field ($ \delta B_r $ ). The electromagnetic particle
flux is observed to be much smaller than the electrostatic particle flux,$
\Gamma_{em}\approx 10^{-5} \Gamma_{es} $ .The EM flux is small but finite
contrary to the conventional slab ETG model. The electromagnetic flux is
non-ambipolar. A theoretical model is obtained for the EM particle flux in
straight homogeneous magnetic field geometry. The theoretical estimates are
seen to compare well with the experimental observations. Sluggish parallel ion
response is identified as the key mechanism for generation of small but finite
electromagnetic flux.
