Optics-measurement-based Beam Position Monitor Calibration. / Garcia-Tabares Valdivieso, Ana (Universidad Complutense (ES))
Accurate measurements of the focusing properties of an accelerator are essential for proper operation of a synchrotron, both for the machine protection and for the performance of the experiment. Measurement of linear optics functions based on turn-by-turn measurements has been developed continuously in pursuit of more accurate results. [...]

Modelling and Control of the HL-LHC Nested Magnet Circuits at CERN / Yammine, Samer (CERN) ; Thiesen, Hugues (CERN)
In the scope of the High Luminosity - Large Hadron Collider project at CERN, six new superconducting quadrupole electromagnets are required for the final focusing of the beam before proton-to-proton collisions. To optimize the powering scheme, the quadrupoles will be powered in series by one high-current two-quadrant converter. [...]

Combined Testing And Validation Strategy For The New LHC Blm Processing Module / Schramm, V (CERN) ; Saccani, M (CERN) ; Viganò, W (CERN) ; Bertsche, B (Stuttgart U.)
A comprehensive strategy to test a new digital acquisition board has been implemented by the Beam Instrumentation Group of the European Organization for Nuclear Research (CERN) as part of a wider methodology for the design, production, test, and operation of high dependability electronic systems. This includes test benches for component and functional testing during production, as well as for validation and burn-in upon reception. [...]
