Summary
--------
Completed lumi checkout tests. HV settings were checked at 2, 5, 10 and
20 uA. Took lumi DAQ linearity test runs on carbon and hydrogen at 2, 5,
10 and 20 uA (hydrogen only). Note that when taking beam on the carbon
target, radiator heats up noticably.
Phillipe has completed the calibration and loaded new HV settings for NA
octants 1, 3, 5 and 7.
