Preliminary AD-Horn Thermomechanical and Electrodynamic Simulations / Lopez Sola, Edmundo (Universidad Miguel Hernandez de Elche (ES)) ; Horvath, David (CERN) ; Calviani, Marco (CERN)
As part of the Antiproton Decelerator (AD) target area consolidation activities planned for LS2, it has been necessary to perform a comprehensive study of the thermo-structural behaviour of the AD magnetic horn during operation, in order to detail specific requirements for the upgrade projects and testing procedures.

The Long-Term Beam Losses in the CERN Injector Chain / Gilardoni, Simone (CERN) ; Bartosik, Hannes (CERN) ; Benedetto, Elena (CERN) ; Damerau, Heiko (CERN) ; Forte, Vincenzo (Universite Blaise Pascal (FR)) ; Giovannozzi, Massimo (CERN) ; Goddard, Brennan (CERN) ; Hancock, Steven (CERN) ; Hanke, Klaus (CERN) ; Huschauer, Alexander (CERN) et al.
For the production of the LHC type beams, but also for the high intensity ones, the budget allocated to losses in the CERN injector chain is maintained as tight as possi- ble, in particular to keep as low as possible the activation of the different machine elements. Various beam dynamics effects, like for example beam interaction with betatronic resonances, beam instabilities, but also reduced efficiency of the RF capture processes or RF noise, can produce losses even on a very long time scale.

Integrating Controls Frameworks: Control Systems for NA62 LAV Detector Test Beams / Holme, Oliver (CERN ; Zurich, ETH) ; Arroyo Garcia, Jonas (CERN) ; Golonka, Piotr (CERN) ; Gonzalez-Berges, Manuel (CERN) ; Milcent, Hervé (CERN)
The detector control system for the NA62 experiment at CERN, to be ready for physics data-taking in 2014, is going to be built based on control technologies recommended by the CERN Engineering group. A rich portfolio of the technologies is planned to be showcased and deployed in the final application, and synergy between them is needed. [...]
