Electron Witness Constraints for AWAKE
/ Farmer, John P (Munich, Max Planck Inst. ; CERN) ; Gschwendtner, Edda (CERN) ; Liang, Linbo (Manchester U.) ; Muggli, Patric (Munich, Max Planck Inst.) ; Weidl, Martin (Garching, Max Planck Inst.)
The AWAKE project at CERN successfully demonstrated the use of a proton driver to accelerate an electron witness in plasma*. One of the key goals for AWAKE Run2 is to better control this acceleration, separating the proton-beam-modulation and electron-acceleration stages in order to achieve high energy electrons with high beam quality.

Simulation Study of Electron Beam Acceleration with Non-Gaussian Transverse Profiles for AWAKE Run 2
/ Liang, Linbo (Manchester U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Farmer, John P (Munich, Max Planck Inst. ; CERN) ; Xia, Guoxing (Cockcroft Inst. Accel. Sci. Tech. ; Manchester U.)
In the physics plan for AWAKE Run 2, two known effects, beam loading the longitudinal wakefield and beam matching to the pure plasma ion channel, will be implemented for the better control of electron acceleration. It is founded in our study of beam matching that the transverse profile of the initial witness beam have a significant impact on its acceleration quality. [...]

Design of the Proton and Electron Transfer Lines for AWAKE Run 2c

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. [...]

Data Acquisition and Controls Integration of the AWAKE Experiment at CERN
/ Olsen, Veronica (Oslo U.) ; Batkiewicz, Jozef (CERN) ; Deghaye, Stephane (CERN) ; Gessner, Spencer (CERN) ; Gschwendtner, Edda (CERN) ; Muggli, Patric (Munich, Max Planck Inst.)
The AWAKE experiment has been successfully installed in the CNGS facility at CERN, and is currently in its first stage of operation. The experiment seeks to demonstrate self-modulation of an SPS proton beam in a rubidium plasma, driving a wakefield of several gigavolt per meter. [...]

Integration of a Terawatt Laser at the CERN SPS Beam for the AWAKE Experiment on Proton-Driven Plasma Wake Acceleration

In the AWAKE experiment a high-power laser pulse ionizes rubidium atoms inside a 10 m long vapor cell thus creating a plasma for proton-driven wakefield acceleration of electrons. Propagating co-axial with the SPS proton beam the laser pulse seeds the self-modulation instability within the proton bunch on the front of plasma creation. [...]

Preparation for Electron-Seeding of Proton Bunch Self-Modulation in AWAKE

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. [...]

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 [...]
