摘要

In this work, we construct electrodes of brass to produce plasma by arc discharge and is characterized by using a movableLangmuir single probe. It is a simple way to measure plasma parameters such as electron temperature, electron density and iondensity. A movable Langmuir single probe technique has a reference point since it is biased with reference to any one electrode ofthe plasma producing system. The values obtained are at atmospheric pressure. The plasma thus produced in laboratory has variousapplications which include gaseous discharge, plasma torch, sputtering, laser produced plasma as well as tokamak plasma.
