Channeling performance of bent crystals developed at CERN
/ Rodin, Volodymyr (CERN) ; Esposito, Luigi Salvatore (CERN) ; Lechner, Anton (CERN) ; Demassieux, Quentin (CERN) ; Matheson, Eloise (CERN) ; Solis Paiva, Santiago (CERN) ; Seidenbinder, Regis (CERN) ; Aberle, Oliver (CERN) ; Perillo Marcone, Antonio (CERN) ; Calviani, Marco (CERN) et al.
Bent crystals are a mature technology used in several applications at CERN, such as the crystal-assisted collimation system for LHC ion operation and reduction of losses during the slow extraction from the SPS by shadowing the electrostatic septum. In the future, it is planned to measure electric and magnetic dipole moments of short-lived particles with a double-crystal experiment in the LHC. [...]

Real time crystal collimation monitoring at the CERN Large Hadron Collider
/ Ricci, Gianmarco (Rome U. ; CERN) ; Mostacci, Andrea (Rome U. ; CERN) ; Mirarchi, Daniele (CERN) ; Matheson, Eloise (CERN) ; D'Andrea, Marco (CERN ; INFN, Legnaro) ; Di Castro, Mario (CERN) ; Cai, Rongrong (CERN) ; Redaelli, Stefano (CERN)
At the CERN Large Hadron Collider (LHC), bent crystals play a crucial role in efficiently redirecting ion-beam halo particles toward secondary collimators used for absorption. This innovative method leverages millimeter-sized crystals to achieve deflection equivalent to a magnetic field of hundreds of Tesla at LHC’s highest energies. [...]

Machine learning based crystal collimator alignment optimization
/ Ricci, Gianmarco (CERN) ; D'Andrea, Marco (CERN) ; Di Castro, Mario (CERN) ; Matheson, Eloise (CERN) ; Mirarchi, Daniele (CERN) ; Mostacci, Andrea (CERN) ; Redaelli, Stefano (CERN)
In the CERN Large Hadron Collider (LHC), bent crystals are used to efficiently deflect beam halo particles toward secondary collimators used as absorbers. In this crystal collimation scheme, a crystal with a length of a few millimeters can produce a deflection equivalent to a magnetic field of hundreds of Tesla at LHC top energies, improving the cleaning performance of the machine.

Collimation of 400 MJ Beams at the LHC: The First Step Towards the HL-LHC Era
/ Redaelli, Stefano (CERN) ; Abramov, Andrey (CERN) ; Baillard, Dylan (CERN) ; Bruce, Roderik (CERN) ; Cai, Rongrong (CERN ; Ecole Polytechnique, Lausanne) ; Carra, Federico (CERN) ; D'Andrea, Marco (CERN) ; Di Castro, Mario (CERN) ; Giacomel, Lorenzo (CERN) ; Hermes, Pascal (CERN) et al.
An important upgrade programme is planned for the collimation system of the CERN Large Hadron Collider (LHC) in order to meet the challenges of the upcoming High-Luminosity LHC (HL-LHC) project. A first stage of the HL-LHC upgrade was already deployed during the last LHC Long Shutdown, offering important improvements of the collimation cleaning, a significant reduction of the impedance contribution and better cleaning of collisional debris, in particular for ion-ion collisions.

SAMbuCa: Sensors Acquisition and Motion Control Framework at CERN
/ Masi, Alessandro (CERN) ; Andreassen, Odd (CERN) ; Arruat, Michel (CERN) ; Danzeca, Salvatore (CERN) ; Di Castro, Mario (CERN) ; Donzé, Mathieu (CERN) ; Fargier, Sylvain (CERN) ; Ferraro, Rudy (CERN) ; Gulin, Marco (CERN) ; Kozsar, Ioan (CERN) et al.
Motion control systems at CERN often have challenging requirements, such as high precision in extremely radioactive environments with millisecond synchronization. These demanding specifications are particularly relevant for Beam Intercepting Devices (BIDs) such as the collimators of the Large Hadron Collider (LHC). [...]
