I have the camera working so I can two pictures during one cycle of the FPGA. I don't see a direct correlation between taking an image after evaporative cooling and before, but this may help if the laser power drifts over time. I also don't see a huge effect with triggering off the line voltage. I'm looking into the evaporative cooling being a part of the noise. Also check noise with and without repumper.

Noise seems to be much better when I take data more randomly and not in a row. For example, don't take 100 data points for the first data set, then 100 for the next and so on....Instead, take 200 points and every other point counts for the first data set, and the other points count for the second. I saw a big improvement doing this with this data that was taken with all FORT conditions the same and no EIT beams. Here are the graphs using the two types of data taking.
