*Online model exploitation
Requirements for optics extractor:
(i) Is it ATS?
(ii) Is it pre-squeeze or squeeze?
(iii) To make on-line model compatible with ATS
There are the 2 solutions to implement both:
-FLAG based, just to pass the info: ATS variable in MADX modifiers.
ATS=0,1,2; (no ATS, pre-squeeze, squeeze)
-Full knob redefinition in on-line model (names are always the same)
Jaime found a bug in the extractor, using a temp file created some problems. Jaime and Elena
Elena: repeated optics names are now removed. The issue of the speed should be checked.
PDF export is ready. Case-by-case. Title should be beam and optics. Not duplicate s labels
and IR labels.
Automatic model generation in multiturn ready!
Ewen requests a settings window for svd clean settings -> Need to copy settings app form bbeat GUI.
-> Ask Jorg to get half an hour at injection
Andreas: Paralelized beta calculation and ADT in model
option in GetLLM for number of process:
-1: max available.
0: is serial,
>4: recommended
Options required: Not to run RDTs, Not to run N-BPM.
New computer as Andreas' desktop is most welcome. Is it because SSD????
Filtering bad BPM combinations, when all BPM combinations are lost fall back to BPMs
(flag for cutting? I recommend not).
Ewen: Plan for IRNL
knobs and on-line model.
Check with Jaime the knob setting history frequency.
Extract trim history files was stopped in LSA, shall we ask Jorg?
Trim history dedicated application.
Orbit? How robust is orbit matching in the IRs? re-sizing crossing angle?
-> need resources for dedicated GUI to deal with orbit
-> tunes with David's work are ok. Next: to extend it to run on pre-extracted data.
Either Ewen or Felix
come back to 10^{-4} analysis f1001.
