Daily Meeting BlueJeans

Production Run List - Slug 122 - IHWP IN - Flip-RIGHT - Production

continue slug 122 from January 31:

• Good - Run 6102
• Good - Run 6103
• Good - Run 6104
• Mixed run - Run 6105 half events of both arm and half events of right arm (LQ2 quenched midway)

Production Run List - Slug 123 - IHWP IN - Flip-RIGHT - Production

separate single arm runs into new slug

• recover needed - Run 6105 somehow separate the right arm events from the double arm events
• Right arm only - Run 6106

Production Run List - Slug 124 - IHWP OUT - Flip-RIGHT - Production

this slug starts at about 3:50 am

• Right arm only - Run 6107
• Right arm only - Run 6108
• Right arm only - Run 6109
• Right arm only - Run 6110: there is an outlier in atr1

Production Run List - Slug 125 - IHWP OUT - Flip-RIGHT - Production

• Good - Run 6115
• Good - Run 6116
• Good - Run 6118
• Good - Run 6119
• Good - Run 6120 - The DD sees large offsets surrounding some laser noise events all throughout, and digitals disagree at 1 or so sigma with analogs DD. BCM mean is poorly constrained by large RMS due to laser noise.
  • Later: Adding cuts at onset of Aq noise and some trip recoveries. Events 20k:30k, 50k:75k, and 150k:250k
• Good - Run 6121
• Good - Run 6122
• Good - Run 6123
• Good - Run 6124

Production Run List - Slug 126 - IHWP IN - Flip-RIGHT - Production

start slug 126 at about 20:50

• Good - Run 6125 - Again, the DD sees large offsets surrounding some laser noise events all throughout, and digitals disagree at 1 or so sigma with analogs DD. BCM mean is poorly constrained by large RMS due to laser noise, again.
  • Later: Adding cuts at onset of Aq noise and some trip recoveries. Events 0:55k, 140k:215k
• Good - Run 6126
• Good - Run 6127
• Good - Run 6128

Issues

• Since run 6099, the bcm asym is quite large (>~ 300 ppm) due to large asym in injector
• LQ2 quenched at about 3:25 am, making run 6105 through 6110 right arm only
• yield_atr1_mean of slug 125 is different from that in slug 124 (though the only difference between the two slugs is that we fixed the quenched LQ2), why change in left magnet will affect right at1?
• the same gap happens to yield of sams
