Presentation materials

  1. 61. Beam current limit for HL-LHC
    Ralph Wolfgang Assmann (CERN)
    10/02/2012, 08:30
    The HL-LHC upgrades require beam currents, that are significantly increased beyond the original specifications of the LHC. The talk will explore expected limitations in hardware systems (including RF power, instrumentation, vacuum), the impact of increased beam losses on quench statistics, risks due to beam current related damage, beam dynamics issues, loss-induced activation and single event upsets

  2. 62. Do we really need an upgrade of the collimation system for HL-LHC?
    Stefano Redaelli (CERN)
    10/02/2012, 08:55
    Several improvements are foreseen for the collimation system during the LS1. The talk will discuss how the new performance level compares with the HL-LHC needs and if further improvements will be needed to be compatible with the high luminosity operations expected for the HL-LHC upgrade .

  3. 63. New Magnets for the IR: how far are we from HL-LHC target?
    Gianluca Sabbi (LBNL)
    10/02/2012, 09:20
    The HL-LHC will benefit from new magnet technology (large aperture, Nb3Sn conductors) already under advanced R&D programs. The talk will review the status and roadmap of the new magnets for the high luminosity interaction regions.

  4. 64. Crab Cavities: from virtual reality to real reality?
    Rama Calaga (CERN)
    10/02/2012, 09:45
    The talk will review the status and roadmap for the crab-cavity system that is foreseen for the HL-LHC upgrade project for luminosity enhancement and leveling.

  5. 65. LHeC and HE-LHC: Accelerator lay-out and challenges
    Frank Zimmermann (CERN)
    10/02/2012, 10:40
    This talk will present a concise description of the layout of the two machines, together with the main accelerator-physics and technology challenges, detail the required LHC modifications, and describe the global schedules with decision points.

  6. 66. Magnet R&D for LHeC and HE-LHC: synergy and competion?
    Luca Bottura (CERN)
    10/02/2012, 11:05
    The new projects heavily rely on new magnet systems. The talk with illustrate the magnet R&D program for the LHeC (accelerator, transfer lines, kickers, interaction regions) and the HE-LHC (main Ring, SPS+, transfer lines, kickers). In particular synergies or parallel roadmaps will be highlighted together with the first steps foreseen for 2012.

  7. 67. SC Cavities R&D for LHeC an HE-LHC
    Erk Jensen (CERN)
    10/02/2012, 11:30
    The new machines HE-LHC and LheC (whether or not linac-ring and ring-ring options will be favored) rely on new RF systems. The talk will analyze the synergies or competitions between the R&D strategies. The first steps foreseen for 2012 will be highlighted.
