Here are graphs from the fusion run. The x-axis is time in minutes.
I used google charts to produce these graphs. This code produces the chart from data in mysql. This code transforms the voltage reading to its corresponding instrument value.
I did a quick and dirty downsampling like this:
resamples = samples.in_groups_of(samples.size/number_of_data_points).map{|slice| slice.average rescue 0}
I’m not certain this is all working correctly, but it seems to add up. One oddity: the voltage drops into the negative; perhaps from disabling the high voltage, I’ll have to confirm that.
This is primarily an end to end test of the data acquisition system.
