Ion currents to cylindrical Langmuir probes for finite ion temperature values: Experimental

A new theoretical model about the ion currents to a cylindrical probe has been developed which takes into account the influence of a finite ion temperature value. The ABR (Allen, Boyd and Reynolds) model, which considers only radial motion for the positive ions, is recovered in the limit of cold ions. In this paper we axe going to show the experimental ion currents obtained in a plasma in which the positive ion temperature effect cannot be neglected
