The neon experiment seemed to have some sort of systematic error with the connections. As mentioned above, the first excitation level was suppose to occur around 16.62eV. Our excitation level falls within this range; however, our error is quite large. Since we used a period of 500s, our measurements were not very precise. As for further improvements, it would be much better to take a period around 4ks so that our data would have a smaller uncertainty.   The result of our argon experiment is not consistent with the theoretical value within uncertainty. In order to figure out what went wrong, we analyzed our apparatus setup. The accelerating voltage went all the way up to 76V 80V, as expected,  in our data files. That %That  shows that the applied voltage is not  at fault. fault nor are the multimeters.  We debugged the circuit to see if we were overloading any part of the circuit, and nothing seemed to be overloaded. %There could be a very small extra resistance from the cables used but that would not have a drastic effect of a 3V difference between the actual energy level and the experimental energy level that we observed. As a result, the only possible explanation seems to be a systematic error caused by the voltage amplification. However, the argon data has a smaller uncertainty, which means the data is more precise, since we used a longer period.  %Therefore, our methods and analysis are correct; however, there seems to be a systematic error with the tube.
