\subsection{Argon Experiment}  This experiment had an identical wiring to the neon experiment. The main difference was the voltage settings for the DC Power Supply. \textbf{(show a wiring diagram of the new set up?)}\\ Supply.\\  After adjusting the voltages until we were able to optimize the anode current verses the accelerating voltage graph, we ended up with these settings:
