  1. FCC-he machine parameters Frank Zimmermann FCC Kick-Off Meeting 14February 2014

  2. Future Circular Collider Study CDR and cost review for the next ESU (2018) • 80-100 km tunnel infrastructure in Geneva area • pp-collider (FCC-hh) defining the infrastructure requirements • e+e- collider (FCC-ee) as potential intermed. step and p-e (FCC-he) option • international collaboration hosted by CERN ~16 T  100 TeVpp in 100 km ~20 T  100 TeVpp in 80 km

  3. deep inelastic eh scattering – glorious history 1911, Ernest Rutherford Coulomb scattering , model of the atom; first observation of inelastic scattering 1953-57 (Nobel Prize 1961) Robert Hofstadter electron scattering in atomic nuclei, structure of the nucleons 1968-69 (Nobel Prize 1990) Jerome Friedman, Henry Kendall , and Richard E. Taylor deep inelastic scattering of electrons on protons and bound neutrons, development of the quark model

  4. key parameters for FCC-he • e±energy = 80 (pol.), 120, 175GeV • p energy = 50 TeV (or equiv. A energy) • #IPs = 1 • IP spot size determined by p • e± current from FCC-ee(baseline) • (if built; SR power ≤ 50 MW) • or • e- current from pushed LHeCERL (backup) • (without FCC-ee)

  5. baseline (!) parameters for FCC-he with FCC-ee

  6. LHeC - ion gaps & circumference gap turn 1 gap turn 2 gap turn 3 FHC IP#2 gap turn 1 gap turn 2 gap turn 3 IP#1 DC=kCLHeC LHC CLHeC=CLHC/n future: CLHeC+=CFHC/m m, n (=3), k: integer

  7. LHeC Higgs factory (LHeC-HF) parameters

  8. preliminary (!) parameters for FCC-he-ERL w/o FCC-ee

  9. ERL electrical power budget

  10. summary • colliding beams from FCC-eeand FCC-hh yields FCC-he luminosity of about 2x1034 cm-2s-1 at Ee=80 GeVand 2x1033 cm-2s-1 at 175 GeV; ERL option would deliver ~6x1033 cm-2s-1 at 60 GeV • total electric power for e branch ~100-150 MW for all cases • running scenarios to be defined: he collisions concurrent with ee and/or hh?optimized parameters (i.e. dedicated he operation)might gain another factor 2-6…

  11. spare slides

  12. ambitious (!) parameters for FCC-he with FCC-ee shown in past workshops (e.g. Beijing 2012)
