Electromagnetic Modelling of Kicker Magnets to Derive Equivalent Circuits / Barnes, Michael J (CERN) ; Bjorkqvist, Oskar (CERN) ; Jensen, Lars (CERN ; Aarhus U.) ; Nielsen, Oliver (CERN ; Aarhus U.)
An equivalent circuit model of a kicker magnet system is an invaluable tool for predicting the performance, studying possible modifications and for helping to diagnose faults. The frequency content of pulses associated with a ferrite loaded transmission line kicker magnet generally extend up to a few tens of MHz: hence, it is feasible to accurately model such a kicker magnet using lumped elements.

UCAP: A Framework for Accelerator Controls Data Processing @ CERN / Cseppentő, Lajos (CERN) ; Büttner, Mark (CERN)
The Unified Controls Acquisition and Processing (UCAP) framework provides a means to facilitate and streamline data processing in the CERN Accelerator Control System. UCAP’s generic structure is capable of tackling classic "Acquisition - Transformation - Publishing/Presentation" use cases, ranging from simple aggregations to complex machine reports and pre-processing of software interlock conditions.

Within the LHC Injector Upgrade (LIU) project, the Super Proton Synchrotron (SPS) needs to be upgraded to inject into the LHC higher intensity and brighter 25-ns bunch spaced beams. To mitigate the Electron Multipacting (E.M.) phenomenon, a well-known limiting factor for high-intensity positively charged beams, CERN developed carbon coatings with a low Secondary Electron Yield (SEY).

Towards the Last Stages of the CERN’s AD-Target Area Consolidation Project and Recommissioning Plans to Resume Operation / Torregrosa, Claudio (CERN) ; Ahdida, Claudia (CERN) ; Bouvard, Aymeric (CERN) ; Broche, Alexandre (CERN) ; Burger, Stephane (CERN) ; Butcher, Mark (CERN) ; Calviani, Marco (CERN) ; Clerc, Vincent (CERN) ; De Macedo, Aurelio (CERN) ; De Man, Sven (CERN) et al.
Antiprotons are produced at CERN at the Antiproton Decelerator (AD) Target Area by impacting 26 GeV/c proton beams onto a fixed target. Further collection, momentum selection, and transport of the secondary particles - including antiprotons - towards the AD ring is realised by a 400 kA pulsed magnetic horn and a set of magnetic dipoles and quadrupoles.
