\end{tabular}   \end{table} \\  The only difference between the apparatus for neon (Fig. \ref{fig:appartus}) and argon is that an additional grounding wire was added between the heater filament  and the cathode accelerating voltage  for argon. The lack of the wire resulted in a floating potential between these two points instead of being at the same potential. By simply adding a wire between these two points, the heater and the cathode,  the problem was solved. However, the lack of connection could have possibly damaged the high voltage supply and the preamp. When we were debugging our experiment, the high voltage supply had a gain of 17V instead of 20V.
