Commissioning plans in Rogelio's slides.

 

Lukas cleaned the python code from 120000 lines to 40000.

Drive has been removed -> It has to be put back!!!!

BPM mode in harpy should be default -> Elena

size and lines of code to be checked -> Elena & Jaime

 

Lukas: Tracking is too slow for tests, they break. Use instead twissToTbT? or stored files? or reduce the server test to a light test?

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

Ana: Paths to calibration files  -> Action Elena make it default in the GUI

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

Andreas: 

ADT + errors  gives 10% more phase beating! possible errors: choosing wrong files in comparisons, physics.

Idendify problem with GetLLM and thin model.

The new GetLLM input would not work now with GUI but there is a backwards compatibility built in,

hopefully temporarily. Action also is to clean new input.

 

Removing bad BPMs removes discrepancies between "free" and "ADT".

Edges have still some problems in free, mmmh.

ADT does not work for beam 2 -> to be fixed.

Take Free, ADT and AC dipole in 2018 commissioning for bench mark.

Local OBServable tesTER: still some problems to be understood -> Test with thin

######

Michael : Default values depending on IP or IR4? 

Review kmod in a next meeting with detailed.

-> Elena & Tobias action: Add a check of Energy in the Java K-mod GUI.

-n: means not autocleaning (autocleaning is default)

Think of making all instrument monitor tkicker by default

###### 

Jaime:  Flat 

To fix the b-beat bump identify local errors with a precise model (b2 + MQT). Then correct with global on the modified data by the local corr.

for HL-LHC try all weight on beta*

######

Joschua: Analytical formulas. Priority is coupling, needs the mapping.

Plot easier things to understand.

#######

Felix: RDT needs phase! next week.

right correction should be green divided by 2.
