    Lukas,  GetLLM progress

    Tests: beam 1, beam 2 (as LHCB2) and beam 4,, to start now.

     

     

    Elena, GUIs

    remove "Send" and "Update Tune"  from the main thread and test before MD.

    Problem to run from anaconda in afs gets very slow. -> python3

    Felix and Elena check the beta-beat drive used as it seems slower than in the past.

    Plan is to migrate to new GETLLM after MD2, small changes to GUI might be needed.

     

    Andreas, SuperKEKB

    2 Measurements successful.. Likely to wait for Paul for analysis.

     

    Felix, Amp. det.

    Amp. det. confirmed to come from IP5 xsing !!!! Are these measurements consistent with 2016 (beta*=60m)?

    One could check a4 from IP1 xsing from 2017 data.

    Josch will do beam 2.

    Results to be put in afs.

    Model predictions -> Josch.

    Send script to plot high order lines to  Dominik -> Felix

    The AC tune  vertical should not be 0.32 + 0.010, because 4Qyac = 0.32 in both beams !!!

    Felix will check if b5 and a5 lines are RDTs or not.

    Need a new AC dipole for HL-LHC !!!

    Plan a meeting with Nicolas to see what could be envisaged for HL -> Aug?

     

     

    Leon, Jaime, Offsets in Q1 from kmod.

    to check, sign, error bars and models.

    Code is not integrated in K-mod -> to be done.

     

    Tune from K-mod

    Effect of orbit in Q1 well understood in simulations of kmod. Coupling seems small but need to test a vertical xsing angle. Measurements could be already compensated for this -> K-mod to be done

     

     

    Josch, Flat optics RDTs and amp det.

    Do MQX corrections still work for flat optics? RDTs seem well corrected, quality depending mostly on minimum beta*.

    Skew errors seem to be more benign in flat optics!

    The amplitude detuning cross term is a bit less well corrected than the direct terms.
