Axial variation of plasma parameters in a multi-dipole discharge plasma in the presence of an ion extraction grid

In this experiment, with the help of a Langmuir probe we estimated the plasma parameters at different axial positions inside a multi-dipole magnetic cage. At one end of the multi-dipole magnetic cage, a negatively biased mesh grid is placed. Important plasma parameter such as the electron density, plasma potential and electron temperature are seen to vary significantly towards the grid from the end of the magnetic filter.
