Data Inverted data  was taken by changing the voltage from $0V - 80V$ with intervals of $0.2V$ when the data wasn't a peak or a dip, and $0.02V$ during the peaks and dips. Due to the inclusion of a high power voltage amplifier (x20 gain) in the circuit, a voltage change of $0.2V$ corresponded to $4V$ of change. Accelerating voltage was measured by the Keithley 2100 multimeter, and graphed against the output voltage using DANA. Figure 3 shows a Frank-Hertz curve for neon given the specified parameters.\\ \newline  The final Frank-Hertz curve of Neon contained 3 dips and 3 peaks. It is important to note that the figure: Frank-Hertz Curve for Neon is not inverted, so the peaks are actually the dips and the dips are actually the peaks. Close observation of the peaks and dips indicates a systematic substructure, but poor data quality meant that it could not be analyzed quantitatively. At the very end of the graph (about $V_{acc}<80V$), the data looks linear. This is consistent with the expected behavior of Neon after it ionizes.
