Cross-field fluxes of the electrons and ions. x profiles of the fluxes perpendicular to the magnetic field lines for the ions (\(\Gamma _{i\perp }\), open circles) and the electrons (\(\Gamma _{e\perp }\), filled squares) at (a) \(z=20\) cm, (b) \(z=25\) cm, (c) \(z=30\) cm, and (d) \(z=35\) cm, together with the plasma density (\(n_p\), crosses). The errors in \(\Gamma _{e\perp }\) and \(n_p\) estimated by repeating 100 shots are about \(2~\%\) for both those respective data sets and smaller than the marker sizes. Detailed error analysis is shown in the ’Method’ section. The yellow-colored regions indicate the radially inward cross-field transport. The cross-field transport by the magnetosonic wave for the electrons drives the inward electron flux overcoming the pressure gradient force and contributes to the current balance with the ions deviating from the magnetic field lines.
