Meeting shifted to Monday 14:30.

OK for the proposed speakers in HSS

Lukas  ###################

IP1 corrections for Q5,Q6 based on ballistic.

 

Michael #####################

kmodulation in IR4. This year more critical.

Error bars need to be revisited. 

Code -> when in the CCC -> End of June

 

Felix    # ###############

Amplitude detuning. Problems with B1V ac dipole. 

Some residual amp det after correction. Refine corr? coming from crossing angle?

comparison plots to come.

beta-beating at 5.7TeV

 

Tobias ##################

chromatic coupling in amplitude. Crossing angles change chrom coup a bit beam 2.

From the measurement the effect of removing one family of KSS is computed. Max a factor 2 wrt no corrections.

Strategy might be turn them off if one fails, but since not critical also ignore is ok.

 

Coupling decay. Chroma corr and orbit corr did not affect C- significantly. b3 affected coupling significantly.

-> misalignment of b3 spool pieces. 

Beam1 data missing.

On-line model work-around on the way.

Try with automatic coupling, success excitation. Not right result yet.

 

Andreas  ###############

New formula.

Phase info getting more local.

 

Elena ########

everything seemed to work!!!

ML/AI , first tests very promissing.
