    Chromatic coupling, Tobias

    The plots are a bit mixed. To be uploaded with correct labels.

    For Beam1 chromatic coupling was well corrected, maybe a bit overcorrected.

    For Beam2 the difference is larger. Maybe this is due to chromaticity. The corresponding knob should be reduced from -1 to -0.6 (Piotr will take care).

     

    Error bars are now in the GUI.

    Comparsion YASP to TbT dispersion
    Tobias shows orbit deviations between YASP and TbT, which are in the range of 0.04mm. . This seems to imply that with the TbT data we are making an error of 0.1m peak in the dispersion, unless it is a calibration issue, in which case a solution might be possible. Maybe we can look at first kicks with small kicks.
    ->Check differences and small kicks.
    -> Non-linear dispersion together with Ewen

     

     

    Re-analysis, Ana

    Offending peak beta-beating disappeared!

     

    Updated plots, Rogelio

     

    Jaime, new model building deployed in GUI!! Run GUI for tests.
