Hi Dr. Pace,

Thank you for the excellent explanation! I am trying to curve fit triple Langmuir probe data and obtain the plasma temperature and density from this curve fitted function. I have three data points to fit with: a point in the ion saturation region, the floating potential, and a point in the electron saturation region. I have tried curve fitting the data to a sigmoidal function and taking the slope in the electron saturation to obtain the electron temperature region but using your data this gives Te=126.94 eV. Do you have any suggestions for how to get a more accurate fit? Are there alternative analysis methods I should be considering? The main issue is that I must assume a thick sheath plasma and as such I cannot use many of the simplifications for triple Langmuir probe data analysis. Thank you! [email removed]
