We describe the implementation of light diagnostics for studying the self-modulation instability of a long relativistic proton bunch in a 10m-long plasma. [...]

The Advanced Wakefield Experiment (AWAKE) aimsto accelerate electrons to particle physics relevant energiesusing self-modulated proton bunches as drivers in a singleplasma. AWAKE is now in its Run 2b (2023-2024), wherethe goal is to stabilise wakefields by using a plasma density step. [...]

Application of a Camera Array for the Upgrade of the AWAKE Spectrometer
/ Senes, Eugenio (CERN) ; Cooke, David (Royal Holloway, U. of London) ; Mazzoni, Stefano (CERN) ; Pannell, Fern (Royal Holloway, U. of London) ; Turner, Marlene (CERN) ; Wing, Matthew (Royal Holloway, U. of London) ; Zevi Della Porta, Giovanni (CERN ; Lindau, Max Planck Inst.)
The first run of the AWAKE experiment successfully demonstrated the acceleration of an electron beam in the plasma wakefields of a relativistic proton beam. The planned second run will focus on the control of the emittance of accelerated electrons, requiring an upgrade of the existing spectrometer. Preliminary measurements showed that this might be achieved by improving the resolution of the scintillator and with a new design of the optical system. This contribution discusses the application of a digital camera array in close proximity of the spectrometer scintillator, to enable the accelerated electron beam emittance measurement..

The AWAKE Run 2 programme and beyond
/ AWAKE Collaboration
Plasma wakefield acceleration is a promising technology to reduce the size of particle accelerators. Use of high energy protons to drive wakefields in plasma has been demonstrated during Run 1 of the AWAKE programme at CERN. [...]

Predicting the Trajectory of a Relativistic Electron Beam for External Injection in Plasma Wakefields
/ Asmus, Felipe Peña (Munich, Max Planck Inst. ; Munich, Tech. U.) ; Velotti, Francesco Maria (CERN) ; Turner, Marlene (CERN) ; Gessner, Spencer (CERN) ; Martyanov, Mikhail (Munich, Max Planck Inst.) ; Bracco, Chiara (CERN) ; Goddard, Brennan (CERN) ; Muggli, Patric (Munich, Max Planck Inst.)
We use beam position measurements over the first part of the AWAKE electron beamline, together with beamline modeling, to deduce the beam average momentum and to predict the beam position in the second part of the beamline. Results show that using only the first five beam position monitors leads to much larger differences between predicted and measured positions at the last two monitors than when using the first eight beam position monitors.

Systematic optics studies for the commissioning of the AWAKE electron beamline

The commissioning of the AWAKE electron beam line was successfully completed in 2018. Despite a modest length of about 15 m, this low-energy line is quite complex and several iterations were needed before finding satisfactory agreement between the model and the measurements. [...]

Status and Prospects for the AWAKE Experiment
/ Turner, Marlene (CERN)
/AWAKE Collaboration
The AWAKE Collaboration is pursuing a demonstration of proton-driven plasma wakefield acceleration of electrons. The AWAKE experiment uses a \SI{400}{GeV/c} proton bunch from the CERN SPS, with a rms bunch length of $6$-\SI{15}{cm}, to drive wakefields in a \SI{10}{m} long rubidium plasma with an electron density of $10^{14}-10^{15}$cm$^{-3}$.

Scintillation and OTR Screen Characterization with a 440 GeV/c Proton Beam in Air at the CERN HiRadMat Facility
/ Burger, Stephane (CERN) ; Biskup, Bartolomej (Prague, Tech. U. ; CERN) ; Mazzoni, Stefano (CERN) ; Turner, Marlene (CERN ; Graz, Tech. U.)
Beam observation systems, based on charged particles passing through a light emitting screen, are widely used and often crucial for the operation of particle accelerators as well as experimental beamlines. The AWAKE experiment, currently under construction at CERN, requires a detailed understanding of screen sensitivity and the associated accuracy of the beam size measurement. [...]
