Agenda

1. Tao - Summary of pairsynch pickup
   • TY: pairsync pickup should be canceled out: KP: we also have multiplet sync that can appear.
   • TY: we don't see it in batteries in detector hut or CH. KP: ususal signal amplitude is around 3 V for BPM and BCM.
   • KP: for BCM noise, it could be Pockel cell history effect as well.
   • KP: a false pickup in BPM can dilute regression slope. What about dithering? TY: will add them
   • TY: bpm4eY also show differences between polarities
   • PK: Because of the 45 degree rotation, pos Y readout may pickup more.
   • Check list: to trace down the source of pick-up
     • averages by polarity from corrections
     • beam-off pedestal noise in main detectors
     • BPM wiresums asymmetries
     • cross comparison between beamline monitors: eg. bcm double-diff
2. Devi - Summary of plots available for At detector asymmetry
   • Have plots ready.
   • KK : we can discuss this over the weekend.
