MCS, Benoit

b3 dipole correction almost verified in Arc 12, vertical tune a bit off. MCS quality to be evaluated (maybe 10% off).

Other arcs to be measured. 

####################################

Beta-from amplitude, Ana

Rather good agreement before corrections.

After corrections differences are apparent.

We should look at the difference b-from-phase and b-from-amplitude and looks at the outliers to identified bad BPMS.

########################################

Non-linear chromaticity, Ewen

Q'' and Q''' a bit larger than in 2011-12

Small discrepancy between "radial loop error" and "radial trim" -> Ask Jorg or Giulia

New corrections calculated with better data: Beam2: MCO 2.48 m^-4, MCD  + 1706.8 m^-5.

Corrections are larger by 46% and 30% in 2012 (but MCD trims are lower!).

####################################################

Chromatic coupling, Tobias

Already nice measurements for chromatic coupling in Beam 2. Phase clearly changed between 2012 and 2015!

And amplitude seems smaller.

In the normal coupling there are 2 jumps. Is it orbit? else, do a global correction?

Amplitude detuning to be compared with 2011 measurements.

Coupling versus kick amplitude without not much change, but no octupoles.

##########################################################

Line (-1,-2), Felix

Line appeared in beam 1 too.

Bug fixed in GetLLM with finding right BPM pair.

Calculate terms from complex spectrum might be more accurate. 

#############################################################

N-BPM method, Andy

Problem at the edges with the beta-beat was actually prepared in the code. Now this fix becomes default.

Try/except in python generated some large error bars, to be followed up with Jaime.

Agreessive cleaning seemed required.

######################################

PSB, Meghan

Lots of electrical noise

66 khz new line, but looks real.

############################################

Action-phase jump, Carolina

IR BPMS are not used now. Simulations show it is possible to use only arc BPMS.

Goal is to compare action phase method to segment-by-segment

Need to learn new sbs.

-> Lukas will help Carolina to regard sbs and action-phase

########################################################

GUI, Jaime

default directories for b2 syst coming.

Optipons for SVD, missing large p2p cut.

Quadrupoles displayed in sbs.

Automatic cleaning to be further investigated.
