Figure 8

Temporal development of the \(n_{\mathrm{e}}\) profile of the pellet-injected plasma which was measured by the 20 kHz operation of the laser. \(n_{\mathrm{e}}\) (blue circles), \(T_{\mathrm{e}}\) (red circles) and the product of \(n_{\mathrm{e}}T_{\mathrm{e}}\) (yellow circles) are shown.
