Non-linear MD Tue 7am: Ewen, Felix, Rogelio, Tobias, Massimo, UK people.
IR aperture MD Wed 4am: Ewen or Rogelio -> Talk to Roderick, Leon
ATS Wed 4pm: Ana, Jaime, Felix, Emilia, Jose, Lukas, Rogelio -> discuss with Stephane UK plans.
DOROS Thu 4am: Tobias, David, Felix, Rogelio....
ATS Sat 11am: Jaime, Lukas, Rogelio, -> confirm with Lukas.
################
Ewen, NL MD plan
b6 effect not so visible, limit 1h of MD to DA
Octupoles shadow any effect of b6. Crossing angle enhances the b6 effect.
###################
Felix, working point for NL MD
To see a4, f1210, f1012, these drive Qx-Qy, move to 0.29, 0.3.
For b4, maybe move Qx towards 0.25.
###############################
David, Tobias, BBQ coupling
-BBQ C- is equivalent to our method
-At large octs the copuling is larger but also the noise is larger!
Octupoles increase detuning, signal to noise ratio is worse -> We were just looking at noise!
-> Evaluate the noise floor.
################################
Jaime, IP1->RPs
Need IP1 both RPs H &V phase
#################################
Ana, Beta from Amplitude
Effect of amplitude in the opposite plane is negligible.
Still need to clean all data and compare to K-mod.
The bpms with bad phase have a bad FFT -> Clean with Drive noise window? yes, possible.
Re-clean with stronger cut in SVD clean.
