H10.00001: Run II of the LHC: The Accelerator Science Invited Speaker: Stefano Redaelli In 2015 the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) starts its Run~II operation. After the successful Run~I at 3.5~TeV and 4~TeV in the 2010-2013 period, a first long shutdown (LS1) was mainly dedicated to the consolidation of the LHC magnet interconnections, to allow the LHC to operate at its design beam energy of 7~TeV. Other key accelerator systems have also been improved to optimize the performance reach at higher beam energies. After a review of the LS1 activities, the status of the LHC start-up progress is reported, addressing in particular the status of the LHC hardware commissioning and of the training campaign of superconducting magnets that will determine the operation beam energy in 2015. Then, the plans for the Run~II operation are reviewed in detail, covering choice of initial machine parameters and strategy to improve the Run~II performance. Future prospects of the LHC and its upgrade plans are also presented. [Preview Abstract] |

H10.00002: Worldwide Activities towards a Future Circular Collider: The Accelerator Invited Speaker: Swapan Chattopadhyay |

H10.00003: Worldwide Activities towards a Future Circular Collider: Physics and Detector Studies Invited Speaker: Michelangelo Mangano Collider rings with circumference in the range of 50-100 km could host electron-positron colliders with center-of-mass energies up to 350 GeV, and proton-proton colliders up to 100 TeV. Two-stage projects, along the lines of the LEP-LHC complex, are under study by the high-energy physics community worldwide. The physics potential of such a future facility spans from improving by orders of magnitude the precision study of the Higgs boson, to extending by a factor of 10 the mass reach for the search of new particles. The talk will review the physics opportunities and the challenges that are emerging from the current studies. [Preview Abstract] |
