Subject: MCIS mass scans & initial emittance scans 

High resolution zero to 25. Save file: masscorr_mcis_090817-highres.txt

Ack! Elog server went down at ~17:00!!!

18O4+ emittance scan at 22.44kV and slits open: 090817_1707ILTEMIT.txt

Note that in preparation for this scan I steered beam in X then in Y onto FC3 and FC6 respectively, looking for all beam through each slit. There was flat-topping evident in both directions for both cups. I would like to repeat the study for well-defined X beam through each slit by scanning with the 1mm slit and noting the drop-off at the tails. For what they're worth, I am appending the stripcharts for each cup. Data files are here:
