  1. 16. Accelerator physics challenges for EIC
    Georg Hoffstaetter (Cornell)
    23/07/2019 14:00

    The Electron Ion Collider optimizes electron and ion beams for high luminosity collisions. For electron/proton collisions, both beams are to be polarized. The accelerator physics challenges are therefore focused on obtaining and maintaining (A) high luminosity and (B) a high degree of polarization. High luminosity provides challenges for (A1) beam currents and for (A2) collision parameters,...

  2. 17. Optimizing the Electron Beam Polarization in High Energy Storage Rings
    Matthias Vogt (DESY-MFL)
    23/07/2019 14:30

    Storing electron bunches with a high degree of polarization will be a key aspect of eRHIC operation.

    This talk will introduce the basic concepts of electron beam polarization and summarize known optimization strategies. Special emphasis will be put on the eRHIC project.

  3. 18. Beam-Beam Simulations with Crab Cavities
    Ji Qiang (Lawrence Berkeley National Laboratory)
    23/07/2019 15:00

    The electron-ion collider as the next generation nuclear physics research facility has great demand for the luminosity of colliding beams. Meanwhile, the effects due to the electromagnetic interactions of the colliding beams, i.e. beam-beam effects, put strong limit on the achievable luminosity. In this talk, we will discuss about the numerical simulations of the beam-beam effects with crab...

  4. 19. Dynamic Aperture in Electron and Ion Colliders
    Yunhai Cai (SLAC)
    23/07/2019 16:00

    Dynamic aperture, defined as a stable region in the six dimensional phase space, is always a challenging design issue in circular accelerators. In hadron rings, it is largely determinants by the magnetic errors in the superconducting magnets in arcs at injection and in the final focusing quadupoles at the collision. In electron machines, it is dominated by the sextupoles that are introduced...

  5. 20. EIC hadron beam cooling
    Sergei Nagaitsev (FNAL)
    23/07/2019 16:30

    This talk will review the main hadron beam heating mechanisms for the existing EIC concepts and will establish the requirements for hadron beam cooling. It will then review the conventional and advanced hadron beam cooling techniques and their present state of the art. An R&D path and associated milestones for various cooling techniques will be also discussed.

  6. 21. Accelerator R&D for the Electron Ion Collider
    Yuhong Zhang
    23/07/2019 17:00

    Designs of two proposed electron-ion colliders, eRHIC at BNL and JLEIC at JLab, are driven by achieving unprecedentedly high performances in collider luminosity, beam polarization and particle detection. To realize such design goals, an arrow of advanced concepts and new accelerator technologies have been integrated into the two collider designs, and several key machine parameters have been...
