The Advanced Wakefield Experiment (AWAKE) at CERN uses bunches from the CERN SPS to develop proton-driven plasma wakefield acceleration. AWAKE Run 2c (starting in 2029) plans for external on-axis injection of a 150MeV electron witness bunch with the goal to demonstrate emittance control of multi-GeV accelerated electron beams. [...]

A method for measuring energy gain with variable plasma length at AWAKE / Pannell, F (Imperial Coll., London) ; Cooke, D A (Imperial Coll., London) ; van Gils, N Z (CERN) ; Gschwendtner, E (CERN) ; Turner, M (CERN) ; Bergamaschi, M (CERN ; Munich, Max Planck Inst.) ; Ranc, L (Munich, Max Planck Inst.) ; Muggli, P (Munich, Max Planck Inst.) ; Wing, M (Imperial Coll., London)
The AWAKE experiment investigates the acceleration of externally injected electrons into the wakefields driven by a self-modulated proton bunch. In Run 1, AWAKE successfully demonstrated proton bunch self-modulation and accelerated electrons from 19 MeV to 2 GeV. [...]

Verification of electron beam alignment and optics for external off-axis injection in AWAKE Run 2b / van Gils, Nikita Z (CERN ; Groningen, KVI) ; Turner, Marlene (CERN) ; Bencini, Vittorio (CERN ; JAI, UK) ; Bergamaschi, Michele (CERN ; Munich, Max Planck Inst.) ; Ranc, Lucas (Munich, Max Planck Inst.) ; Pakuza, Collette (CERN) ; Pannell, Fern (U.

The Advanced Wakefield Experiment (AWAKE) has the long term goal to accelerate electrons to particle physics relevant energies using self-modulated proton bunches as drivers in plasma. AWAKE is currently in its Run 2b (2023–2025), where the goal is to stabilise the wakefield amplitude after the saturation of the self-modulation process by introducing a plasma density step. [...]

Implementation of Light Diagnostics for Wakefields at AWAKE / Mezger, Jan (Munich, Max Planck Inst. ; Tech. U., Munich (main)) ; Bergamaschi, Michele (Munich, Max Planck Inst. ; CERN) ; Ranc, Lucas (Munich, Max Planck Inst.) ; Sublet, Alban (CERN) ; Pucek, Jan (Munich, Max Planck Inst. ; CERN) ; Turner, Marlene (CERN) ; Clairembaud, Arthur (Munich, Max Planck Inst. ; Tech. U., Munich (main)) ; Muggli, Patric (Munich, Max Planck Inst.)
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 wakefields driven by the proton bunch dissipate their energy in the surrounding plasma. [...]

Measurement of the emittance of accelerated electron bunches at the AWAKE experiment / AWAKE Collaboration
The vertical plane transverse emittance of accelerated electron bunches at the AWAKE experiment at CERN has been determined, using three different methods of data analysis. [...]

Experimental observation of the motion of ions in a resonantly driven plasma wakefield accelerator / AWAKE Collaboration
We show experimentally that an effect of motion of ions, observed in a plasma-based accelerator, depends inversely on the plasma ion mass. The effect appears within a single wakefield event and manifests itself as a bunch tail, occurring only when sufficient motion of ions suppresses wakefields. [...]

Filamentation of a Relativistic Proton Bunch in Plasma / AWAKE Collaboration
We show in experiments that a long, underdense, relativistic proton bunch propagating in plasma undergoes the oblique instability, that we observe as filamentation. We determine a threshold value for the ratio between the bunch transverse size and plasma skin depth for the instability to occur. [...]

Generation of 10-m-lengthscale plasma columns by resonant and off-resonant laser pulses / Demeter, G. (Wigner RCP, Budapest) ; Moody, J.T.

(CERN) ; Muggli, P. (Munich, Max Planck Inst.) ; Panuganti, H. (CERN) ; Della Porta, G. Zevi (Munich, Max Planck Inst. ; CERN)
Creating extended, highly homogeneous plasma columns like that required by plasma wakefield accelerators can be a challenge. We study the propagation of ultra-short, TW power ionizing laser pulses in a 10-meter-long rubidium vapor and the plasma columns they create. [...]

Techniques to seed the self-modulation instability of a long proton bunch in plasma / Verra, Livio (CERN) ; Bergamaschi, Michele (Munich, Max Planck Inst.) ; Zevi Della Porta, Giovanni (CERN ; Munich, Max Planck Inst.) ; Gschwendtner, Edda (CERN) ; Muggli, Patric (Munich, Max Planck Inst.)
The Advanced Wakefield Experiment (AWAKE) at CERN relies on the seeded Self-Modulation (SM) of a long relativistic proton bunch in plasma to accelerate an externally injected MeV witness electron bunch to GeV energies. During AWAKE Run 1 (2016-2018) and Run 2a (2021-2022), two seeding methods were investigated experimentally: relativistic ionization front seeding and electron bunch seeding. [...]
