Measurement diagram of ion nonextensive parameter of plasma generated by 36815 shot on T-10 device. The four curves are the \({{q}_{{{F}_{\text {i}}}}}-{q}\) figure given by Eq. (2) combining with the slope \(\sqrt{{S}}={1.003}\) (Table 1) obtained from Fig. 3. As you can see from the diagram, there are four groups of solutions, and here, from a physical point of view, we only consider the group of solutions represented by the red real curve. \({{q}_{{{F}_{\mathrm {i}}}}}={1.565}\) is the ion nonextensive parameter of plasma generated by 36815 shot (safety factor¹¹ \({q}={3.3}\)) on T-10 device.
