The main aspects linked to Landau damping of head-tail instabilities at top energy in the HL-
LHC are discussed, in particular the interplay between the arc octupoles and long-range …

Optics control in the HL-LHC will be challenged by a very small β* of 15 cm in the two main
experiments. HL-LHC physics fills will keep a constant luminosity during several hours via β …

Type-II superconductors, like the Nb 3 Sn 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 …

Since the publication of the document providing the specifications of the new circuits of the
HL-LHC (see CERN-ACC-2017-0101), using criteria based on beam dynamics …

Several transverse noise sources, such as power supply ripple, can potentially act as an
important limiting mechanism for the luminosity production of the Large Hadron Collider …

A new digitizer, the HPM7177, which is a fundamental component of the signal chain for
high precision measurement of particle accelerator magnet currents, is presented. It was …

The goal of the High-luminosity upgrade of the LHC is to deliver an integrated luminosity of
at least 250 fb-1 per year (assuming at least 160 days of operation at high-luminosity) in …

A superconducting magnet for particle accelerators is often modeled as an ideal inductor, as
it indeed exhibits a completely negligible resistance; this is fully satisfactory, as an example …

The High Luminosity Large Hadron Collider project at CERN requires performance
improvements in the precision powering of magnets, in particular for the new Nb3Sn based …

Certain magnet power supplies for particle accelerators demand a high consumption of
pulsed power, which generates perturbations in the electrical grids located in urban zones …
