Saskia, Simulations with non-linear model

Triplet errors do not affect amp det... -> bug in the script, mad?

Octupolar errors of triplet do not vary with seeds.

Model to be checked (different MAD versions gave same result).

-------------------------------------------------------------------------------------

Ana, Beta from amplitude

First indication for a systematic 10% lower calibration in W BPMS.

--------------------------------------------------------------------------------------

Andy, dispersion at 40cm

removing the 0 dpp helped a lot for the dispersion error bar -> Next measurement take many points

around 0Hz.

Before and after corrections at 40cm dispersion improved in Beam1, Beam2 stayed similar.

Lukas (via Andy), ESRF MD

0.1% quad grad error was crushes twiss, reduced to 0.08% to allow for twiss.

Simulations predict below 1% resolution!

dispersion is not yet working -> to be followed up by Jaime.

Lukas implemented a routine to compute noise level in SVD clean -> to be discussed with Jaime.

Tobias and Piotr might join ESRF MD
