Agenda

Analysis projects

  1. Devaki:
    • DA: don't see any difference in the Q2 from the weighting with the ADC value; L and R seems to not produce any difference
    • DA: took a look at all the runs and I see no difference.
    • KP: you need to weight by the pedestal subtracted ADC
    • PK: pedestal subtracted ADC vs Q2
    • CG: Marisa updated the plots and is officially off this project but is still in touch (if needed).
  2. Yufan:
    • DP: he is flying back and should have something by next week
  3. Tao: dithering correction for slug 0,7 HAPLOG 4011
    • TY: two slugs don't have beam mod data (0 and 7).
    • TY: slug 0 and 1 had only 3 complete supercycles. The problem seems to be that coil 7 (energy) had some readback problem. YT: before 3302 we didn't have the correct readback (a cable was unplugged).
    • TY: for slug 0 we can use dithering slopes for the second half and regression for the first half
    • TY: slug7: because of the slopes not being stable KP: this really looks like strength sharing; PK: finding large slopes that cancel each other out.

    • KP: can we make plots for all slugs in a wein similar to the plots Tao created for 0-1, 6-7; TY: will try to get that
  4. Devi: Qsq with and without Detector ADC weights HAPLOG4006
    • CG: Marisa updated the plots and is officially off this project but is still in touch (if needed). Marisa Petrusky: slides
    • DA: don't see any difference in the Q2 from the weighting with the ADC value; L and R seems to not produce any difference
    • DA: took a look at all the runs and I see no difference.
    • KP: you need to weight by the pedestal subtracted ADC
    • PK: pedestal subtracted ADC vs Q2

PREX Respin

  1. Robert: respin update
    • CG: did we finish the respin? RR: it has been much slower than usual because we are trying to let MOLLER to go ahead and submit jobs.
    • CG: where can we find the data? RR: we are puting them on tape; plots are being put on the respin page; PK: will help with putting the ouput on the tape directory
    • CG: how should we access the data? PK: we will keep as much on volatile as we can; the rest will be in cache. CG: for now this sounds like a good setup; the analyzers can work on the stuff that is on volatile and when we know what we want from the entire dataset we'll use the farm to get the files from tape.
