Production Run List - Slug 110 - IHWP IN - Flip-RIGHT - Production

  • Good - Run 5786 - some beam motion, but not > 0.5 mm, so leaving it in. Clear 60 Hz noise in the beam... FFB seems to be off. Some <150 uA data, but its short and OK (wider widths)
  • Good - Run 5787 - looks good. Similar not-quite-cuttable beam motion at the beginning. Some clipping in the injector for a moment
  • Good - Run 5788 - beam excursion at the end, and large Aq wings at the beginning. Cut out 375000-> and 10k-20k
  • Good - Run 5789 - bad Y beam motion. Cutting out 125000:140000, 160000:190000, 340000:360000
  • Good - Run 5790
  • Good - Run 5791 - cutting out 170K onward due to large beam motion
  • Good - Run 5792 - wild beam instability up to 175K cut, otherwise good
  • Good - Run 5793 - pretty bad clipping in injector this time... cut 200-260k
  • Good - Run 5794 - beam motion towards the end in Y - cutting 270000:320000, and 340000:370000
  • Good - Run 5795 - the beam moves around a bit. Clean RMS on the main detectors :)

Non-Production Runs and Bad Runs

Pedestal/Calibrations Updates

Issues

  • Cut out lots of clipping in the injector. It isn't necessary for our data quality, so consider undoing
