Shower simulations for the CERN proton synchrotron internal dump and possible shielding options / Niang, Samuel (CERN) ; Huschauer, Alexander (CERN) ; Esposito, Luigi Salvatore (CERN) ; Giovannozzi, Massimo (CERN) ; Pugnat, Thomas (CERN)
During the Long Shutdown 2, the two internal dumps were replaced and successfully integrated into the CERN Proton Synchrotron operation to withstand the intense and bright beams for the High-Luminosity LHC. They function as safety devices, designed to swiftly intersect the beam’s trajectory and effectively stop the beam over multiple turns. [...]

Energy deposition in the new SPS's scrapers / Niang, Samuel (CERN) ; Esposito, Luigi Salvatore (CERN)
The successful injection of proton beams into the Large Hadron Collider (LHC) depends on an efficient scraping mechanism in the Super Proton Synchrotron (SPS). The beams accelerated in the SPS contain a significant non-Gaussian tail population. [...]

Radiation to electronics studies for CERN gamma factory-proof of principle experiment in SPS / Mazzola, Giuseppe (CERN) ; Di Francesca, Diego (CERN) ; Bilko, Kacper (CERN) ; Esposito, Luigi Salvatore (CERN) ; Garcia Alia, Ruben (CERN) ; Niang, Samuel (CERN) ; Dutheil, Yann (CERN)
The Physics Beyond Colliders is a CERN exploratory study aimed to fully exploit the scientific potential of its accelerator complex. In this initiative, the Gamma Factory experiment aims to produce in the Large Hadron Collider (GF@LHC) high-intensity photon beams in the energy domain up to 400 MeV. [...]

Radiation levels in the LHC tunnel and impact on electronics during the 2023 Pb ion run / Canesse, Auriane (CERN) ; Ricci, Daniel (CERN) ; Söderström, Daniel (CERN) ; Di Francesca, Diego (CERN) ; Tagkoudi, Eirini (CERN) ; Cerutti, Francesco (CERN) ; Lerner, Giuseppe (CERN) ; Garcia Alia, Ruben (CERN) ; Fiore, Salvatore (CERN) ; Niang, Samuel (CERN)
The 2023 operation of the Large Hadron Collider (LHC) at CERN included a one-month-long run with fully stripped Pb ion beams, marking the first heavy-ion run since 2018, and delivering Pb ion collisions at an unprecedented center-of-mass energy of 5.36 TeV per nucleon pair. During this period, the radiation fields in the LHC tunnel have been measured by means of different radiation monitors, including Beam Loss Monitors (BLMs), RadMons, and distributed optical fiber dosimeters, with the primary goal of quantifying the radiation exposure of electronic systems.

Study of the Performance of the CERN Proton Synchrotron Internal Dump / Pugnat, Thomas (CERN) ; Domange, Delphine (Brussels U.) ; Esposito, Luigi Salvatore (CERN) ; Giovannozzi, Massimo (CERN) ; Gnacadja, Eustache (Brussels U.) ; Hernalsteens, Cédric (CERN) ; Huschauer, Alexander (CERN) ; Niang, Samuel (CERN) ; Tesse, Robin (Brussels U.)
In the framework of the LHC Injector Upgrade project, a new internal dump for the CERN Proton Synchrotron (PS) has been designed, installed, and successfully commissioned. This device is meant to move rapidly into the beam and stop charged particles over several turns to provide protection to the PS hardware against beam-induced damage. [...]

Shower Simulations for the CERN Proton Synchrotron Internal Dump and Comparison with Beam Loss Monitor Data / Niang, Samuel (CERN) ; Domange, Delphine (U. Brussels (main)) ; Esposito, Luigi Salvatore (CERN) ; Giovannozzi, Massimo (CERN) ; Hernalsteens, Cédric (CERN) ; Huschauer, Alexander (CERN) ; Pugnat, Thomas (CERN)
During the Long Shutdown 2 (LS2), two new internal dumps (TDIs) were installed and successfully put into operation in the CERN Proton Synchrotron (PS) to withstand the intense and bright beams produced for the High Luminosity LHC. TDIs serve as safety devices designed to rapidly enter the beam trajectory and stop the beam over multiple turns. [...]
