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. [...]

The AWAKE Experiment in 2021: Performance and Preliminary Results on Electron-Seeding of Self-Modulation
/ Gschwendtner, Edda (CERN) ; Muggli, Patric (Munich, Max Planck Inst.) ; Verra, Livio (CERN) ; Zevi Della Porta, Giovanni (CERN)
/AWAKE Collaboration
The future programme of the Advanced Wakefield (AWAKE) experiment at CERN relies on the seeded self-modulation of an entire proton bunch, resulting in phase-reproducible micro-bunches. This important milestone was achieved during the 2021 proton run by injecting a short electron bunch ahead of the proton bunch, demonstrating for the first time the electron-seeding of proton bunch self-modulation [...]

Preparation for Electron-Seeding of Proton Bunch Self-Modulation in AWAKE
/ Zevi Della Porta, Giovanni (CERN) ; Gschwendtner, Edda (CERN) ; Moon, Kookjin (UNIST, Ulsan) ; Muggli, Patric (Munich, Max Planck Inst.) ; Verra, Livio (CERN ; Munich, Max Planck Inst.)
The next milestone of the Advanced Wakefield Experiment (AWAKE) at CERN will be to demonstrate that the self-modulation of a long proton bunch can be seeded by a short electron bunch preceding it. This seeding method will lead to phase-reproducible self-modulation of the entire proton bunch, as required for the future AWAKE program. [...]

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. [...]

Determination of the Charge per Micro-Bunch of a Self-Modulated Proton Bunch using a Streak Camera
/ Bachmann, A.-M (CERN ; Munich, Max Planck Inst. ; Munich, Tech. U.) ; Muggli, P. (CERN ; Munich, Max Planck Inst.)
The Advanced Wakefield Experiment (AWAKE) develops the first plasma wakefield accelerator with a high-energy proton bunch as driver. The 400GeV bunch from CERN Super Proton Synchrotron (SPS) propagates through a 10m long rubidium plasma, ionized by a 4TW laser pulse co-propagating with the proton bunch. [...]

Seeding of the Self-Modulation in a Long Proton Bunch by Charge Cancellation with a Short Electron Bunch
/ Hüther, Mathias (Munich, Max Planck Inst. ; Munich, Tech. U.) ; Muggli, Patric (Munich, Max Planck Inst. ; CERN)
In plasma wakefield accelerators (e.g. AWAKE) the proton bunch self-modulation is seeded by the ionization front of a high-power laser pulse ionizing a vapour and by the resulting steep edge of the driving bunch profile inside the created plasma. [...]
