Meeting 31/01/06: Roger, Elvin, Brennan, Jan, Verena, Jorg, Mike.
- already done
Would expect semi-automatic procedures for checking optics - extraction point, Delphine's dispersion measurement analysis, matching through the screens, response analysis. Can't ever imagine this being fully automatic.
- v1 already available in YASP - not a major issue but should check trimming across TI2/LHC boundary. Orbit bumps in LHC (circulating beam).
Semi-automatic - sorted
LOCO analysis - LHC sector test trajectory response analysis c/o Jorg, but want off-line simulation of what we might be able to observe. How well can we get the phase advance given BPM response, kick amplitude, permitted momentum offset etc. Also to be extended to the case of circulating beam.
Do we need the detailed magnet model on-line? (Indiviudal error assingment etc.)
For sector test look at transmission efficiency (BCT) - would certainly like to be able to automated scan sequence. On-line aperture model required also.
- given magnet errors, BPM resolution etc., proposed measurement techniques - what can we get a handle on?
Should be prepared in advance.
Possibility of LARP picking up the beta beating analysis problem in collaboration with ABP discussed. Imagine this as off-line analysis attempt to find source of beating. Feed forward and re-measure. On-line analysis of multi-turn data to produce beating measurement.
