Chromaticity measurement using the beam transfer function (MD 6803) / Buffat, Xavier (CERN) ; Giacomel, Lorenzo (CERN) ; Mounet, Nicolas (CERN) ; Soderen, Martin
Chromaticity measurement at the LHC is based on energy modulation which is incompatible with high intensity beam operation. [...]

Chromaticity Measurement based on Beam Transfer Function: Non-Linear Fits and Deep Learning / Vicentini, Giulio
At the Large Hadron Collider (LHC), the stability of the beams is one of the most important characteristic that has to be ensured in order to not compromise the accelerator performances. [...]

Magnetic Analysis of the MQXF Quadrupole for the High Luminosity LHC / Izquierdo Bermudez, S (CERN ; Madrid Politecnic U., ETSI Minas) ; Fiscarelli, Lucio (CERN) ; Ambrosio, Giorgio (Fermilab) ; Bajas, Hugues (CERN) ; Chlachidze, Guram (Fermilab) ; Ferracin, Paolo (CERN) ; DiMarco, Joseph (Fermilab) ; Stoynev, Stoyan Emilov (Fermilab) ; Todesco, Ezio (CERN) ; Sabbi, GianLuca (LBL, Berkeley) et al. /LARP
The high-luminosity upgrade of the large hadron collider (HL-LHC) requires new high-field and large-aperture quadrupole magnets for the low-beta inner triplets (MQXF). The US Hilumi-LHC Accelerator Upgrade (HL-LHC AUP) and CERN are jointly developing a 150 mm aperture Nb3Sn magnet. [...]

Beam Transfer Function Measurements and Transverse Stability in presence of Beam-Beam / Tambasco, Claudia (Ecole Polytechnique, Lausanne) ; Barranco, J (Ecole Polytechnique, Lausanne) ; Pieloni, T (Ecole Polytechnique, Lausanne) ; Rivkin, L (Ecole Polytechnique, Lausanne) ; Buffat, X (CERN) ; Métral, E (CERN)
Instability thresholds are explored at the Large Hadron Collider (LHC) by means of the computation of the Landau Stability Diagram (SD). In the presence of diffusive mechanisms, caused by resonance excitations or noise, the SD can be reduced due to the modification of the particle distribution inside the beam. [...]
