Consolidation of the Superconducting Circuits Energy Extraction Systems at the Large Hadron Collider / Pojer, Mirko (CERN) ; Aas, Jan-Erik (CERN) ; Carrillo, David (CERN) ; Coelingh, Gert-Jan (CERN) ; Donato, Alessandro (CERN) ; Georgakakis, Spyridon (CERN) ; Grigorov, Martin (CERN) ; Panev, Bozhidar (CERN) ; Pemberton, Stephen (CERN) ; Pirc, Vasja (CERN)
At the beginning of the next long shutdown, fore- seen mid 2026, the Large Hadron Collider (LHC) will have been in operation for almost 20 years. After this period, the opera- tion of the present Energy Extraction (EE) systems, that are part of the protection of the superconducting circuits of the LHC, will present significant challenges.

Radiation protection challenges in the upgrade, autopsy and disposal of the LHC beam dump / Infantino, Angelo (CERN) ; Bernardes, Ana-Paula (CERN) ; Calviani, Marco (CERN) ; Dumont, Gerald (CERN) ; El-Idrissi, Safouane (CERN) ; Mouret, Renaud (CERN) ; Tromel, Christophe (CERN) ; Vincke, Heinz (CERN)
The upgrade of the Large Hadron Collider spare beam dumps (Target Dump External, TDE) and the autopsy of the old operational TDE required to perform several activities in a high-radiation environment posing significant radiation protection challenges due to the residual activation of the equipment. To ensure high safety standards and to respect the ALARA principle, these challenges were addressed using the advanced Monte Carlo techniques to predict the residual ambient dose equivalent rate and the radionuclide inventory at different steps of the interventions.

Radiation protection challenges for the Large Hadron Collider upgrade / Elie, Lucie (CERN) ; Dyrcz, Patrycja (CERN) ; Infantino, Angelo (CERN) ; Tromel, Christophe (CERN) ; Vincke, Heinz (CERN)
In the context of the so-called Long Shutdown 3 (2026–2028), the Large Hadron Collider will be upgraded to the High-Luminosity Large Hadron Collider, allowing for approximately five more instantaneous collisions. The upgrade, maintenance and decommissioning of equipment will be mainly performed in the experimental insertions of Points 1 and 5, requiring to perform multiple interventions in high-residual radiation environment.

Operational radiation protection challenges for the LHC experiments / Bozzato, Davide (CERN ; KIT, Karlsruhe) ; Froeschl, Robert (CERN) ; Kouskoura, Vasiliki (CERN)
Radiation protection physicists at CERN are often required to assess residual activation for the Large Hadron Collider (LHC) experiments during stop periods in order to ensure adequate optimization during planned exposure situations and to establish proper procedures for the radiological control of materials. Given the complexity of the facilities and of the high-energy and mixed fields inducing the activation, Monte Carlo transport codes are an essential tool to simulate both prompt and residual radiation.

Linear Colliders / Stapnes, Steinar (CERN)
This article summarizes the studies for implementation of the Linear Collider projects, CLIC (the Compact LInear Collider) and ILC (the International Linear Collider). The accelerators aim to collide electrons and positrons at 380 and 250 GeV respectively, and both can be extended in length and/or with improved technologies to multi-TeV energies. [...]
