New local optics measurements and correction techniques for the LHC and its luminosity upgrade
(American Physical Society (APS), 2020-04-06)
Article
Open AccessAs the beams at the interaction points (IPs) of circular colliders are pushed toward smaller sizes, the correction of the magnetic field errors in high- ß regions become increasingly important, but also challenging. This ... -
Impact of flux jumps in future colliders
(American Physical Society (APS), 2020-01-02)
Article
Open AccessType-II superconductors, like the Nb3Sn used in the new HL–LHC quadrupole triplet and 11 T dipoles or FCC dipoles, are known to show an unstable behavior during magnetic-field ramps. This paper presents an analysis of the ... -

Improving the precision of linear optics measurements based on turn-by-turn beam position monitor data after a pulsed excitation in lepton storage rings
(American Physical Society (APS), 2018-08-04)
Article
Open AccessBeam optics control is of critical importance for machine performance and protection. Nowadays, turn-by-turn (TbT) beam position monitor (BPM) data are increasingly exploited as they allow for fast and simultaneous measurement ... -
New approach to LHC optics commissioning for the nonlinear era
(American Physical Society (APS), 2019-06-21)
Article
Open AccessIn 2017, optics commissioning strategy for low- ß * operation of the CERN Large Hadron Collider (LHC) underwent a major revision. This was prompted by a need to extend the scope of beam-based commissioning at high energy, ... -
LHC optics commissioning: A journey towards 1% optics control
(American Physical Society (APS), 2017-06-19)
Article
Open AccessSince 2015 the LHC has been operating at 6.5 TeV. In 2016 the ß -functions at the interaction points of ATLAS and CMS were squeezed to 0.4 m. This is below the design ß * = 0.55 ¿ ¿ m at 7 TeV, and has been instrumental ... -
Utilizing the N beam position monitor method for turn-by-turn optics measurements
(American Physical Society (APS), 2016-09-21)
Article
Open AccessThe N beam position monitor method ( N -BPM) which was recently developed for the LHC has significantly improved the precision of optics measurements that are based on BPM turn-by-turn data. The main improvement is due to ... -
Experimental validation of the Achromatic Telescopic Squeezing (ATS) scheme at the LHC
(Institute of Physics (IOP), 2017-07-27)
Article
Open AccessThe Achromatic Telescopic Squeezing scheme offers new techniques to deliver unprecedentedly small beam spot size at the interaction points of the ATLAS and CMS experiments of the LHC, while perfectly controlling the chromatic ... -
A compact fission detector for fission-tagging neutron capture experiments with radioactive fissile isotopes
(2020-04-21)
Article
Open AccessIn the measurement of neutron capture cross-sections of fissile isotopes, the fission channel is a source of background which can be removed efficiently using the so-called fission-tagging or fission-veto technique. For ... -
Measurement of the 154Gd(n,gamma) cross section and its astrophysical implications
(Elsevier, 2020-05-10)
Article
Open AccessThe neutron capture cross section of 154Gd was measured from 1 eV to 300 keV in the experimental area located 185 m from the CERN n_TOF neutron spallation source, using a metallic sample of gadolinium, enriched to 67% in ... -
Shear Alfvén wave continuum spectrum with bifurcated helical core equilibria
(2019-09-09)
Article
Open AccessThe radial structure of the continuum spectrum of shear Alfvén and Alfvén-acoustic waves in the beta-induced Alfvén eigenmode (BAE) frequency range is modeled for tokamak plasmas in the presence of 3D effects obtained from ... -
Methodology for the improvement of the AINA code wall-model applied to DEMO WCPB blanket
(2017-11)
Article
Open AccessThe present work describes and supports the methodology for the improvement of the wall model devel-oped in AINA and its specific application to the Japanese DEMO Water Cooled Pebbled Bed. The set-upand application of this ...
