The measurement of plasma quantities is a difficult task since the plasma cannot be treated like normal material. Any measurement of plasma quantities with solid electrostatic probes will yield interactions with the plasma and causes a perturbation of the measured quantity. Inside a hot plasma those methods are not applicable, since they lead to a disruption of the discharge.
