Operational experience of beam stability control

R. Steerenberg

The CERN accelerator complex, as well as other accelerator facilities world-wide, produce a large variety of particle beams for use in experiments. The beam quality is of prime importance and can be characterised by many parameters, such as beam or bunch intensity, …

BE Department Annual Report 2019

Paul Collier, Gianluigi Arduini, Ronny Billen, Eugenia Hatziangeli et autres

The Beams Department hosts the Groups responsible for the beam generation, acceleration, diagnostics, controls and performance optimization for the whole CERN accelerator complex. This Report describes the 2019 highlights for the BE Department.

The Largest Accelerators and Colliders of Their Time

Kurt Hübner, Sergei Ivanov, R. Steerenberg, T. Roser et autres

Abstract The Study Group for a GeV-scale Proton Synchrotron was launched in 1952 at CERN. Initially, an up-scaled version of the 3 GeV Cosmotron was considered but soon a new design based on the newly discovered alternating-gradient principle and promising a proton …

LHC Status and Outlook to the HL-LHC

R. Steerenberg

The CERN Large Hadron Collider (LHC) is in its final year of Run 2. The 2-year long shutdown (LS2) will start in 2019 during which the LHC injector Upgrade (LIU) project will be deployed, the first step towards the High Luminosity LHC …

HE-LHC: The High-Energy Large Hadron Collider

A. Abada, M. Abbrescia, Shehu AbdusSalam, I. M. Abdyukhanov et autres

In response to the 2013 Update of the European Strategy for Particle Physics (EPPSU), the Future Circular Collider (FCC) study was launched as a world-wide international collaboration hosted by CERN. The FCC study covered an energy-frontier hadron collider (FCC-hh), a highest-luminosity high-energy …

Operation and Performance of the Cern Large Hadron Collider During Proton Run 2

R. Steerenberg, Markus Albert, R. Alemany–Fernández, Theodoros Argyropoulos et autres

Run 2 of the CERN Large Hadron Collider (LHC) was successfully completed on 10th December 2018, achieving largely all goals set in terms of luminosity production. Following the first two-year long shutdown and the re-commissioning in 2015 at 6.5 TeV, the beam …

New Beam Permit Process for the Proton Synchrotron Complex

Raul Valera Teruel, F. Chapuis, Jose-Luis Duran-Lopez, Christelle Gaignant et autres

Injecting beams in CERN facilities is subject to the CERN safety rules. It is for this reason that the Beam Permit approval procedure was improved by moving away from a paper-based workflow to a digital form. For each facility the Beam Permits …

Operation Challenges and Performance of the LHC During Run II

R. Steerenberg, J. Wenninger

The CERN Large Hadron Collider Run II saw an important increase in beam performance through both, improvements in the LHC and an increased beam brightness from the injectors, leading to a peak luminosity that exceeds the LHC design luminosity by more than …
