keyword=Current scan for lumi detectorThe plots shows the result of the current scan done yesterday. First canvas shows raw lumi rates vs beam current, they scale very well. Second canvas shows the lumi rate(normalized by the BCM u10 rate) versus beam current. Below ~3uA the it is not linear. I will change HVs and do this test again to see if this improves at low current. Also, BCMs themselves may not be linear at below 2uA.
