摘要：
The characteristics of Langmuir probes have been calculated for such electron temperatures (greater-than-or-equal-to 15 eV) where the probe surface emits secondary electrons. Under these conditions, the floating potential of the probe shifts towards the plasma potential. The calculations provide a guideline by which to determine the plasma potential near the edge of fusion plasmas more accurately.
