baseline decisions
Baseline Decisions
  • Retain a two-stage bunch compressor
  • Reduced field Flux Concentrator for e+ source
  • 500 MV s-band linac for auxiliary positron source
  • Include e+/e- production overhead (margin) in specification for RF

  • Adjustment of the damping ring transfer lines (Central Region)
  • Physics related instrumentation accepted as proposed.
  • BDS/FFS length fixed at current length
other issues discussed
Other issues discussed
  • Global timing
    • Finalisation of path length for TDR
    • Understand construction tolerance (survey)
