Commissioning of ALPS, the New Beam Position Monitor System of CERN’s Super Proton Synchrotron / Boccardi, Andrea (CERN) ; Albertone, Joel (CERN) ; Barros Marin, Manoel (CERN) ; Bogey, Thierry (CERN) ; Kain, Verena (CERN) ; Li, Kevin S B (CERN) ; Malinowska, Patrycja A (CERN ; AGH-UST, Cracow) ; Topaloudis, Athanasios (CERN) ; Wendt, Manfred (CERN)
The Super Proton Synchrotron (SPS) is both, the final machine in the pre-accelerator chain of the Large Hadron Collider (LHC) at CERN, and a machine providing several experiments with proton and ion beams. In the framework of CERN’s LHC Injectors Upgrade (LIU) project, aimed at improving the performances of the pre-accelerators in view of the high-luminosity upgrade of the LHC, the Beam Position Monitor (BPM) system of the SPS was redesigned during Run 2 of the LHC and deployed during the subsequent Long Shutdown 2 (LS2).

The CERN Super Proton Synchrotron (SPS) uses 215 beam position monitors (BPMs) to observe the beam orbit when accelerating protons or ions on a fast ramp cycle to beam energies of up to 450 GeV/c. In the frame of the CERN LHC Injector Upgrade (LIU) initiative the aged, and difficult to maintain homodyne-receiver based BPM read-out system is currently being upgraded with A Logarithmic Position System - ALPS.

The Advanced Proton Driven Plasma Wakefield Acceleration Experiment (AWAKE), based at CERN, explores the use of a proton driven plasma wake-field to accelerate electrons at high energies over short distances. This paper introduces the Beam Position Measurement (BPM) system of the proton beamline and its performance. [...]

Upgrade of the CERN SPS Beam Position Measurement System / Wendt, Manfred (CERN) ; Barros Marin, Manoel (CERN) ; Boccardi, Andrea (CERN) ; Bogey, Thierry (CERN) ; Degl'Innocenti, Irene (CERN) ; Kain, Verena (CERN) ; Moran Guizan, Carla (CERN) ; Topaloudis, Athanasios (CERN)
The CERN Super Proton Synchrotron (SPS) is a fast cycling hadron accelerator delivering protons with momenta of up to 450 GeV/c for the Large Hadron Collider (LHC), fixed target experiments and other users such as the AWAKE plasma acceleration experiment, and also used to accelerate heavy ions. This paper presents the upgrade initiative for the SPS beam position measurement system in the frame of the CERN LHC Injector Upgrade (LIU) project. [...]

Experimental observation of proton bunch modulation in a plasma, at varying plasma densities / AWAKE Collaboration
We give direct experimental evidence for the observation of the full transverse self-modulation of a relativistic proton bunch propagating through a dense plasma. The bunch exits the plasma with a density modulation resulting from radial wakefield effects with a period reciprocal to the plasma frequency. [...]

Experimental observation of plasma wakefield growth driven by the seeded self-modulation of a proton bunch / AWAKE Collaboration
We measure the effects of transverse wakefields driven by a relativistic proton bunch in plasma with densities of $2.1\times10^{14}$ and $7.7\times10^{14}$ electrons/cm$^3$. We show that these wakefields periodically defocus the proton bunch itself, consistently with the development of the seeded self-modulation process. [...]

Beam Instrumentation Developments for the Advanced Proton Driven Plasma Wakefield Acceleration Experiment at CERN / Mazzoni, Stefano (CERN) ; Barros Marin, Manoel (CERN) ; Biskup, Bartolomej (CERN ; Prague, Tech.

The Advanced Proton Driven Plasma Wakefield Acceleration Experiment (AWAKE) at CERN aims to develop a proof-of-principle electron accelerator based on proton driven plasma wake-field acceleration. The core of AWAKE is a 10 metre long plasma cell filled with Rubidium vapour in which single, 400 GeV, proton bunches extracted from the CERN Super Proton Synchrotron (SPS) generate a strong plasma wakefield.

AWAKE readiness for the study of the seeded self-modulation of a 400\,GeV proton bunch / AWAKE Collaboration
AWAKE is a proton-driven plasma wakefield acceleration experiment. % We show that the experimental setup briefly described here is ready for systematic study of the seeded self-modulation of the 400\,GeV proton bunch in the 10\,m-long rubidium plasma with density adjustable from 1 to 10$\times10^{14}$\,cm$^{-3}$ [...]
