\subsection{Argon Experiment}  This experiment had an identical wiring to the neon experiment. The main difference was the voltage  settings of for  the devices. DC Power Supply.  \\[Should I include the systematic method used to adjust the voltage settings???]   A common issue that was encountered was the grounding. Since it is very hard to see the connections inside the argon or neon tube, the best way to debug the grounding issues was by guessing and checking. For the argon experiment, we had a grounding issue between the cathode and heater. This was simply solved by connecting a wire between those two points. However, every tube is different, which means that the apparatus should always be tested more than once before sending high voltage and current through the circuit.  After adjusting the voltages until we were able to optimize the anode current verses the accelerating voltage graph, we ended up with these settings:  

Sensitivity: 20pA/V & Period: 4ks & Control Grid Voltage: 1.49V \\   & HiLev: 6V & Reverse Bias Voltage: 11.5V \\   \end{tabular}   \end{table} A common issue was encountered that for the argon experiment was grounding.
