Abstract

To achieve the edge plasma properties, 2 electronic circuit have been fabricated and a set of 4 single Langmuir probes installed in Iran -Tokamak1 (IR-T1). The Floating Potential has been measured without applying any voltage, Ion Saturation Current by a negative DC power supply and then by applying a sweep voltage to tips, I-V curve and so electron temperature is obtained. Then we compare these results to investigate of some properties of edge plasma.
