  1. 0. A Monte Carlo Simulation of the Equilibrium Beam Polarization At Ultra-High Energy Electron (Positron) Storage Rings
    Dr Zhe DUAN (Institute of High Energy Physics, Chinese Academy of Sciences)
    With the recently emerging global interest in building a next generation of circular electron–positron colliders to study the properties of the Higgs boson, and other important topics in particle physics at ultra-high beam energies, it is also important to pursue the possibility of implementing polarized beams at this energy scale. It is therefore necessary to set up simulation tools to...

  4. 7. LEP Polarization Experience
    Prof. Alain Blondel (DPNC, Université de Genève)
  5. 3. Multi turn ERL's - a new instrument for high energy spin physics
    Dr Kurt Aulenbacher (Institut für Kernphysik, Universität Mainz)
    Several multi turn ERL facilities are under construction or are in the design phase. These upcoming small scale machines can be considered as forerunners for spin-polarized electron - nucleon colliders. The ERL designs for Cornell , CERN and Mainz/MESA are introduced and the extrapolation to future large scale colliders will be discussed.

  6. 6. Overview of polarized electron and positron sources
    Louis Rinolfi (CERN)
    After a recall on the methods to produce polarized electron beams and polarized positron beams, an overview is given about the performance of lepton sources in the world oriented towards high energy colliders. The experience gained by the 2 major colliders (SLC and LEP) is compared to the requirements for future high energy colliders and challenges are pointed out.

  7. 4. Performance of a HERMES Polarised Internal Target in the LHC (and) FCC
    Prof. Paolo Lenisa (University of Ferrara and INFN)
    The presentation will address the potentialities and technical requirements related to the introduction of a polarised internal target a-la HERMES (DESY) in the LHC and FCC rings.

    Dr Vadim Ptitsyn (Brookhaven National Laboratory)
  9. 8. Polarization study for CEPC
    Dr Zhe DUAN (Institute of High Energy Physics, Chinese Academy of Sciences)
  10. 9. Polarization wigglers for FCC-ee (TLEP) and lessons from LEP
    Michael Koratzinos (University of Geneva)
  11. 5. Prospects for polarization at FCC-ee
    Eliana Gianfelice (Fermilab)
    The use of resonant depolarization has been suggested for precise beam energy measurements in the FCC-ee for Z and WW physics at 90 and 160 GeV CM energy respectively. In addition longitudinal beam polarization would benefit the Z peak physics program. The large time constant of self-polarization (Sokolov-Ternov effect) in such a large ring can be greatly reduced by inserting proper...

    Wolfgang Hillert (University of Bonn, Physics InstituTe, ELSA)
