Emissive Probe

A floating emissive probe has been used to obtain the spatial electron temperature (Te) profile in a 13.56 MHz parallel plate capacitive coupled plasma. The effect of an external transverse magnetic field and pressure on the electron temperature profile has been discussed. In the un-magnetised case, the bulk region of the plasma has a uniform Te. Upon application of the magnetic field, the Te profile becomes non-uniform and skewed.  With increase in pressure, there is an overall reduction in electron temperature. The regions adjacent to the electrodes witnessed a higher temperature than the bulk for both cases. The emissive probe results have also been compared with particle-in-cell simulation results for the un-magnetised case.

AbstractThe plasma temperature in a new plasma source shows unusual behaviour at low pressures (about 1 mTorr) and high absorbed powers. In Ar plasma at pressures of about 1 mTorr, the electron temperature shows a pronounced maximum inside an electromagnetic accelerator, which is followed by a rapid drop at the boundary between the accelerator region and the main chamber. In this paper a neoclassical thermo-conductivity model based on the analysis of the electron trajectories is proposed to describe the sharp electron temperature profile. Quantitative agreement of the calculated temperature profile with the experiment is observed.
