keyword=Lumi asymmetry during run 2357Here is the "normalized lumi asymmetry" screen for run 2357. I was
told that the RMS reading should be around 400ppm and no larger than
500ppm, but here I have several channels above 600ppm. Beam current
was 29uA (stable), position was <0.3mm (normal). We also started a
run to check the raster size, spot++ readings look okay (see 2nd
graph below). Target temperature is 7.0K w/ fan speed 48%.
Everything looks normal. I am confused.
