Investigation of Plasma Parameters in a Duopigatron Using a Langmuir Probe

To design an extraction electrode system for a duopigatron ion source, the SNOW [1] computer simulation has been used. Plasma parameters such as electron and ion current density, electron and ion temperatures are used in the SNOW. We have designed and constructed a Langmuir probe to investigate the plasma parameters in a duopigatron ion source. The probe has been designed in such a way that the plasma can be sampled through the source aperture. This paper will discuss some of the source's parameters, the Langmuir probe design and the plasma parameters of the source.
