The first proton run of the LHC was very successful and resulted in important physics discoveries. It was followed by a two-year shutdown where a large number of improvements were carried out. In 2015, the LHC was restarted and this second run aims at further exploring the physics of the standard model and beyond at an increased beam energy. This article gives a review of the performance achieved so far and the limitations encountered, as well as the future challenges for the CERN accelerators to maximize the data delivered to the LHC experiments in Run 2. Furthermore, the status of the 2016 LHC run and commissioning is discussed.

The international Future Circular Collider (FCC) study is designing hadron, lepton and lepton-hadron colliders based on a new 100 km tunnel in the Geneva region. The main focus and ultimate goal of the study are high-luminosity proton-proton collisions at a centre-of-mass energy of 100 TeV, using 16 T Nb3Sn dipole magnets. Specific FCC beam dynamics issues are related to the large circumference, the high brightness - made available by radiation damping -, the small geometric emittance, unprecedented collision energy and luminosity, the huge amount of energy stored in the beam, large synchrotron radiation power, plus the injection scenarios. In addition to the FCC-hh proper, also a High-Energy LHC (HE-LHC) is being explored, using the FCC-hh magnet technology in the existing LHC tunnel, which can yield a centre-of-mass energy around 25 TeV.

LHC Collimation for the Run Ii and Beyond

S. Redaelli
CERN, Geneva, Switzerland

The LHC achieved in 2015 record stored beam energies of about 280MJ with 6.5TeV proton beams, surpassing by about 2 orders of magnitudes achieved in previous superconducting colliders. The LHC collimation system played a key role in this achievement, ensuring a safe operation well below quench limits of superconducting magnets. In this paper, the collimation system for the LHC Run II is presented. Accelerator physics and operational challenges for controlling LHC beam losses are discussed and the collimation performance is reviewed. Limitations of the system and requirements for operating the LHC beyond Run II are also reviewed.
