1. A method for measuring an ion nonextensive parameter of a plasma, comprises:
step 1, describing the plasma with nonextensive statistical mechanics to obtain an equation describing a relationship between a geodesic acoustic mode frequency and an ion acoustic speed of plasma;
step 2, measuring the geodesic acoustic mode frequency by a heavy ion beam probe (HIBP) and a plasma temperature by a nonextensive electric probe, and collecting measurement data of the geodesic acoustic mode frequency and the plasma temperature in a device where the plasma is to be measured; wherein the device where the plasma is to be measured is a target tokamak device;
step 3, using the equation describing the relationship between the geodesic acoustic mode frequency and the ion acoustic speed of plasma derived in step 1 to obtain a slope value by linearly fitting the measurement data of the geodesic acoustic mode frequency and the plasma temperature collected in step 2 in the device where the plasma to be measured; and
step 4, according to the equation obtained in step 1 and the slope value obtained in step 3, combined with a safety factor of the device where the plasma is to be measured to obtain the ion nonextensive parameter by numerical solution as a measurement result of the plasma in the target tokamak device.
