In order to find the causes of the strong anomaly of current-voltage characteristics of Langmuir probe observed in detached recombining plasmas in a linear divertor plasma simulator, NAGDIS-II, we have investigated plasma resistance along a magnetic field and potential fluctuations in the detached recombining plasmas. Simple calculation on the ratio between the plasma length, at which plasma resistance and resistance of ion sheath formed around a probe tip become equal, and an electron collection length indicates that the evaluation of electron temperature Te becomes inaccurate at Te of less than 0.6 eV when plasma density and neutral pressure are 1.0 × 1018 m-3 and 10 mtorr, respectively. The potential fluctuation in detached recombining plasmas was found to be so large compared to Te/e, which can also modify the probe characteristics.
