Optics-measurement-based Beam Position Monitor Calibration. / Garcia-Tabares Valdivieso, Ana
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 [...]

Advancing the CERN proton synchrotron multiturn extraction towards the high-intensity proton beams frontier / Huschauer, A (CERN) ; Bartosik, H (CERN) ; Cettour Cave, S (CERN) ; Coly, M (CERN) ; Cotte, D (CERN) ; Damerau, H (CERN) ; Di Giovanni, G P (CERN) ; Gilardoni, S (CERN) ; Giovannozzi, M (CERN) ; Kain, V (CERN) et al.
Complementary to the physics research at the LHC, several fixed-target facilities receive beams from the LHC injector complex. To serve the fixed-target physics programme at the super proton synchrotron, high-intensity proton beams from the proton synchrotron are extracted using the multiturn extraction technique based on trapping parts of the beam in stable resonance islands.

Optics measurements in the CERN PS Booster using turn-by-turn BPM data / Garcia-Tabares Valdivieso, Ana (UCM, Somosaguas) ; Skowroński, Piotr (CERN) ; Tomás García, Rogelio (CERN)
As part of the LHC Injector Upgrade Project the injection of the CERN PS Booster will be changed to increase intensity and brightness of the delivered beams. The new injection scheme is likely to give rise to beta beating above the required level of 5% and new measurements are required. [...]

Transverse emittance studies at extraction of the CERN PS Booster / Antoniou, Fanouria (CERN) ; Albright, Simon (CERN) ; Asvesta, Foteini (CERN) ; Bartosik, Hannes (CERN) ; Di Giovanni, Gian Piero (CERN) ; Forte, Vincenzo (CERN) ; Fraser, Matthew (CERN) ; Valdivieso, Ana (CERN) ; Huschauer, Alexander (CERN) ; Mikulec, Bettina (CERN) et al.
Transverse emittance discrepancy in the beam transfer between the Proton Synchrotron Booster (PSB) and the Proton Synchrotron (PS) is observed in operational conditions for the LHC beams at CERN. The ongoing LHC Injectors Upgrade (LIU) project requires a tight budget for beam degradation along the injector chain and therefore the reason for this emittance discrepancy needs to be understood. [...]

Identification and compensation of betatronic resonances in the Proton Synchrotron Booster at 160 MeV / Santamaría García, Andrea (CERN) ; Albright, Simon (CERN) ; Antoniou, Fanouria (CERN) ; Asvesta, Foteini (CERN ; Natl. Tech. U., Athens) ; Bartosik, Hannes (CERN) ; Di Giovanni, Gian Piero (CERN) ; Mikulec, Bettina (CERN) ; Rafique, Haroon (CERN)
The Proton Synchrotron Booster (PSB) is the first circular accelerator in the injector chain to the Large Hadron Collider (LHC) and accelerates protons from 50 MeV to 1.4 GeV. The PSB will need to deliver two times the current brightness after the LHC Injectors Upgrade (LIU) in order to meet the High Luminosity LHC (HL-LHC) beam requirements. [...]

Commissioning of a new digital transverse damper system at the PSB / Di Giovanni, Gian Piero (CERN) ; Antoniou, Fanouria (CERN) ; Blas, Alfred (CERN) ; Brischetto, Ylenia (CERN) ; Findlay, Alan (CERN) ; Kotzian, Gerd (CERN) ; Mikulec, Bettina (CERN) ; Sterbini, Guido (CERN)
At the CERN Proton Synchrotron Booster, PSB, an analog transverse damper system has been in operation since 1999, providing satisfactory operational results with the proton beam supplied by Linac2. As a consequence of the LHC Injectors Upgrade, the PSB will face new challenges imposed by higher intensity, injection and extraction energy. [...]
