Design of the new 18 MeV electron injection line for AWAKE Run2c
/ Bencini, Vittorio (CERN ; JAI, UK) ; Velotti, Francesco (CERN)
The Advanced Wakefield Experiment (AWAKE) has demonstrated during its first run (Run1, concluded in 2018) the capability of accelerating electrons up to the energy of 2 GeV using proton driven plasma wakefield acceleration. AWAKE Run 2 has started and during the third phase of the program, Run 2c, which aims to demonstrate stable accelerating gradients of 0.5-1 GV/m and emittance preservation of the electron bunches during acceleration, the layout of the experiment will be modified to accommodate a second plasma cell.

Design of the proton and electron transfer lines for AWAKE Run 2c
/ Ramjiawan, R (CERN) ; Bencini, V (JAI, UK ; CERN) ; Burrows, P N (JAI, UK) ; Velotti, F M (CERN)
The Advanced Wakefield (AWAKE) Run 1 experiment, which concluded in 2018, achieved electron acceleration to 2GeV via plasma wakefield acceleration driven by 400GeV, self-modulated proton bunches extracted from the CERN SPS. The Run 2c phase of the experiment aims to advance these results by demonstrating acceleration up to about 10GeV while preserving the quality of the accelerated electron beam. [...]

Design of the Proton and Electron Transfer Lines for AWAKE Run 2c
/ Ramjiawan, Rebecca (JAI, UK ; CERN) ; Döbert, Steffen (CERN) ; Farmer, John (Munich, Max Planck Inst. ; CERN) ; Gschwendtner, Edda (CERN) ; Muggli, Patric (Munich, Max Planck Inst. ; CERN) ; Velotti, Francesco (CERN) ; Verra, Livio (CERN)
The AWAKE Run 1 experiment achieved electron acceleration to 2 GeV using plasma wakefield acceleration driven by 400 GeV, self-modulated proton bunches from the CERN SPS. The Run 2c phase of the experiment aims to build on these results by demonstrating acceleration to ~10 GeV while preserving the quality of the accelerated electron beam. [...]

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. [...]

Beam characterization and optimisation for AWAKE 18 MeV electron line
/ Bencini, V (CERN ; JAI, UK) ; Doebert, S (CERN) ; Gschwendtner, E (CERN) ; Granados, E (CERN) ; Velotti, F M (CERN) ; Verra, L (CERN) ; Zevi Della Porta, G (CERN ; Munich, Max Planck Inst.)
After the successful conclusion of Run1 in 2018, the AWAKE experiment is presently undergoing its second phase (Run2), which aims to demonstrate the possibility of producing high quality electron beams for high energy physics applications. Over the last year, a significant time-investment was made to study proton beam centroid modulation effects in plasma induced by a seeding electron bunch (i.e. [...]
