FiDeL - task force

17 April 2008

why a crisis now
Why a crisis now ?
  • The AB-OP team (LSA) runs the commissioning with the theoretical transfer functions derived from the layout file
    • Constant B/I
    • Wrong values by several %
    • The errors (dipoles) are not modeled
  • Circuit parametrization is requested for now, only NS is working on this
how to get out of the blues
How to get out of the blues
  • Jump to the objective
    • Use the present data structure (not complete, not completely coherent)
    • Split the magnets in families (see table)
    • Assign a responsible and cognizable person to each family, who
      • Looks for the data (wherever the data is, in whichever form) and sorts it
      • Models the data to extract fit parameters
      • Judges whether the fit is appropriate/stable/good
      • Tests the model
      • Provides as a result the set of parameters in the presently defined format to AB-OP who centralizes this result
packages of work
Packages of work
  • Each package requires about 3 pmw
    • Excel tool for model evaluation: PH
    • MB: NS
    • MQ: TBD
    • MQM: NCL (help from WVD for the data)
    • MQY: NCL (help from WVD for the data)
    • D1…D4: JM
    • MQX: ET
    • MQW: GdR ? - data provided by MB
    • MBW MBXW, MCBW: TBD - data provided by MB
    • Correctors: VR+RW (internal split) (help from WVD for the data)
    • Dynamic model: NS
  • Book-keeping of data, www page: LD
  • Cycling specification: RW+GD
background tasks
Background tasks
  • Complete the data validation, correction when necessary, indexing and storage. Coordinated by RW
  • Define and execute dedicated measurement programs. Coordinated by AV
    • Snap-back correlation with FAME
    • Tracking re-test (LSA validation, b3/B2 tracking in SSS)
    • Low current and cycle dependence for MQM and MQY (vertical and horizontal)
