  1. FiDeL:Work Program Data and Model Deniau Laurent – AT/MTM Laurent Deniau - AT/MTM

  2. Project Goals • A Field Description of the LHC to: • Describe the magnetic state of the LHC • Provide settings in the main magnets (MB, MQ, MQM, MQY, MQXx) and in the corrector circuits to prepare the LHC for injection, program the ramp, and reach known and corrected coast conditions • Provide trims for correction circuits during constant current plateaus, and especially to follow the field drift at injection • Provide trims for correction currents during the energy ramp, and especially during the snap-back at the beginning of the acceleration Laurent Deniau - AT/MTM

  3. AT contribution Description 1/2 AB ? AB-OP TS-IC AT-MAS AT-MEL AT-MTM AT-MAS AT-MTM TS-SU FiDeL AB-ABP TS-SU Reminder: magnetic re-set cycles Laurent Deniau - AT/MTM

  5. Magnets Overview • Correctors/Trims • Main optics Laurent Deniau - AT/MTM

  6. Work Program - MBs • Warm data • produce a validated set of cold mass data (MAS, proposed ET+PH) • Cold data • re-hash in progress, new data set should be ready by mid October (210 magnets to date) • produce reference data set (MTM, NS+AB+LD+DS+SS) • Model • update warm-cold correlation • test / adapt model on a magnet-by-magnet and family basis (MTM) Laurent Deniau - AT/MTM

  7. Work Program - MQs • Warm data • produce a validated set of cold mass data, including correction for permeability (MAS, proposed ET+PH) • Cold data • after completing MB, revise reference data (35 magnets to date) • produce reference data set (MTM, NS+AB+LD+DS+SS) • Model • update warm-cold correlation • test / adapt model on a magnet-by-magnet and family basis (MTM) Laurent Deniau - AT/MTM

  8. Work Program - MQMs • Warm data • recover and validate measurements performed in industry or at CERN • produce a reference data set (MEL + MAS (?)) • Cold data • recombine SM-18 and B4 data (check with SS and WVD) • establish cross-correlation • produce a reference data set (MTM, proposed SS+WVD) • Model • establish warm-cold correlation • test / adapt model on a magnet-by-magnet and family basis (?) Laurent Deniau - AT/MTM

  9. Work Program - MQYs • Warm data • recover and validate measurements performed in industry or at CERN • correct for non-nominal permeability and produce a reference data set (MEL + MAS (?)) • Cold data • recombine SM-18 and B4 data (check with SS and WVD) • establish cross-correlation • produce a reference data set (MTM, proposed SS+WVD) • Model • establish warm-cold correlation • test / adapt model on a magnet-by-magnet and family basis (?) Laurent Deniau - AT/MTM

  10. Work Program - MQXs • Warm & cold data • recover warm and cold measurements from KEK and FNAL • Compile data in a reference data set (MTM, proposed LD) • Model • establish warm-cold correlation • test / adapt model on a magnet-by-magnet basis (?) Laurent Deniau - AT/MTM

  11. Work Program – Cold D1-D4 • Warm & Cold data • recover warm and cold measurements from BNL (MTM, proposed LD) • Model • establish warm-cold correlation • test / adapt model on a magnet-by-magnet basis (?) Laurent Deniau - AT/MTM

  12. Work Program - MQTLHs • Warm data • compile warm data (partial integral and few complete integrals, xx magnets, to be checked with Nuria) (?) • Cold data • recombine cold SM-18 and B4 data (check with SS and WVD) • produce a reference data set (?) • Model • validate warm-warm cross-correlation from partial integral to complete integral • establish warm-cold correlation for local values • test / adapt model on magnets set (Q6) basis (?) Laurent Deniau - AT/MTM

  13. Work Program - Correctors • Conceptual • define the level of details necessary and define family of magnets (MEL, proposed RW+VR) • Warm & cold data • compile warm data (industry benches) and cold data (B4) • produce a reference data set (MEL + MTM, proposed RW+VR+WVD) • Model • establish warm-cold correlation • test / adapt model on data set by family • establish an hysteresis model • test hysteresis model on dedicated experiments (?) Laurent Deniau - AT/MTM

  14. Work Program – Resistive Magnets • Conceptual • define the level of details necessary and define family of magnets (MEL + MTM, proposed SR+MK+DC) • Data • compile data to produce a reference data set (MEL + MTM, proposed SR+MK+DC) • Model • test model on data set by family (?)
