  1. Requirements on fill-to-fill reproducibility • Based on the presentation given by Stephane to FQWG on 26/04/2004 in the framework of the analysis of the RMS system • Some additions to take into account magnets other than MBs and MQs S. Fartoukh, M. Giovannozzi LHCCWG - September 11th 2007

  2. Introduction • The analysis is based on relaxed requirements for reproducibility of magnetic field quality of LHC magnets: • Needs during commissioning phase. • Needs during nominal operation split into: • Machine tuning with a pilot • Nominal Intensity LHCCWG - September 11th 2007

  3. Needs during commissioning - I Some margin available Hard limit SF, FQWG meeting 26/04/04 LHCCWG - September 11th 2007

  4. Needs during commissioning - II Some margin available Hard limit SF, FQWG meeting 26/04/04 LHCCWG - September 11th 2007

  5. Needs for nominal operation: tuning with pilot or few nominal bunches - I Some margin available Hard limit SF, FQWG meeting 26/04/04 LHCCWG - September 11th 2007

  6. Needs for nominal operation: tuning with pilot or few nominal bunches - II Some margin available Hard limit SF, FQWG meeting 26/04/04 LHCCWG - September 11th 2007

  7. Demands for nominal operation - I SF, FQWG meeting 26/04/04 LHCCWG - September 11th 2007

  8. Demands for nominal operation - II SF, FQWG meeting 26/04/04 LHCCWG - September 11th 2007

  9. Summary for MBs and MQs Figures are in units. Limits for random components are expressed in rms. LHCCWG - September 11th 2007

  10. Summary for other magnets Relevant harmonics: b3, b5 Relevant harmonics: b6 Relevant harmonics: b3, b6 MO: crucial to have zero field at injection! Some margin available Hard limit LHCCWG - September 11th 2007
