2015 Commissioning preparation

Present: Andy, Felix, Meghan, Jaime, Ana, Tobias, Rogelio.
############
Jaime gives the first presentation on GUI status. The beam entry at the start reflects now the sequence, since the LHC sequence changed during LS1. In the IR optics options there is beta* files + two for injection. This needs to be clarified. Numerical sorting on beta* would be preferred.
New option to extract MQTs via TIMBER database. The model has 3 templates: best knowledge, twiss and response matrix. Needs some unification to save on model maintenance.
6000 turns is now available. Automatic splitting should be useful for fast measurements.
The new computed dp/p is added in one column in the analysis panel.
GUI Testing plan:
-Tobias segment-by-segment. Already the MQSX magnets are not in the sbs file. Probably IR2 L skew quad is not operational. Avoid putting names that are not operational (new sequence).
-MQTs -> Jaime and CCC
-Amplitude detuning with natural tunes -> Ewen and Ana
-PSB -> Meghan and Ana
-PSB systematic errors -> Andy, Meghan, Ana
-PSB tune input into model -> Jaime and Meghan
-New action file used in GUI? Status? -> Ewen and Ana
-Is it possible to change tunes by 1 integer in the GUI? -> Jaime
###################33
Andy
New coupling knobs with new available skew quads: IP7 looks the appropriate one now.
-> Send to knobs to Matteo and Jorg for use in LSA. Update our coupling correction with Tobias. Put the MAD jobs into the repository check with Jaime.
New optics model: New directory incomplete -> Check with Riccardo for plan and timeline.
DOROS BPMs might create problems. Let's not select them for the time being, to be checked.
b2 dipole errors updated for all energies in 0.5 TeV in repository.
For systematic errros a plan is needed, afs (extra space), CCC (cannot access from office)? -> Let's ask for extra 100 GB afs (not necessarily backed-up). -> Rogelio creates a new OMC
Regenerate systematic error calculations with new misalignment.
##############
Ewen, Amplitude detuning
Knobs from 2012 prepared for 2015 on the slides.
List of tasks, food for thought in the slides.
->Contact Matteo to check that MCO, MCD are useable from trim editor
###########################
Ana, beta-beat from amplitude and beta-beat vs kick amplitude
->Use of systematic errrors to be checked, N-BPM method?
Rescaled beta-from amplitude helps!
-> Beta-beating produced by changing tunes by 1 integer?
##########################
Tobias, commissioning plan
-> MSS, amp det and non-lin chrom correction not optimum but to be followed up.
