keyword=Background electron detectorBackground of the Compton electron detector degrades at lower current, I did not want to change any settings on the beam so just took a bit of data a different current to try to understand the background. One possibility is halo comes in and strips loose efficiency. The nice Compton is a 100 uA the other plot is at 5 uA, it is similar shape at 10 uA. Needs a bit of thinking about how to proceed... handed beam back for production and phase advance tune
