Beam physics studies for a high charge and high beam quality laser-plasma accelerator
/ Marini, Samuel (IRFU, Saclay, DACM) ; Minenna, Damien F G (IRFU, Saclay, DACM) ; Massimo, Francesco (LPGP, Orsay) ; Batista, Laury (IRFU, Saclay, DACM) ; Bencini, Vittorio (CERN) ; Chancé, Antoine (IRFU, Saclay, DACM) ; Chauvin, Nicolas (IRFU, Saclay, DACM) ; Doebert, Steffen (CERN) ; Farmer, John (Munich, Max Planck Inst.) ; Gschwendtner, Edda (CERN) et al.
Electron acceleration by laser-plasma techniques is approaching maturity and is getting ready for the construction of particle accelerators with dedicated applications. We present a general methodology showing how beam physics studies can be used to achieve a specific parameter set in a laser-plasma accelerator. [...]

EARLI: design of a laser wakefield accelerator for AWAKE
/ Minenna, D F G (IRFU, Saclay) ; Ballage, C (LPGP, Orsay) ; Bencini, V (CERN) ; Bethuys, S (Thales Alenia Space France, Cannes La Bocca) ; Cros, B (LPGP, Orsay) ; Dickson, L (LPGP, Orsay) ; Doebert, S (CERN) ; Farmer, J (Munich, Max Planck Inst.) ; Gschwendtner, E (CERN) ; Jeandet, A (Thales Alenia Space France, Cannes La Bocca) et al.
Following the successful Run 1 experiment, AWAKE has developed a program for Run2 that requires designing and implementing a compact electron source (150 MeV, >= 100 pC) for external injection. The baseline design uses a S- and X-band RF photo-injector gun system. [...]

Hosing of a long relativistic particle bunch in plasma
/ AWAKE Collaboration
Experimental results show that hosing of a long particle bunch in plasma can be induced by wakefields driven by a short, misaligned preceding bunch. Hosing develops in the plane of misalignment, self-modulation in the perpendicular plane, at frequencies close to the plasma electron frequency, and are reproducible. [...]

Characteristics of betatron radiation in AWAKE Run 2 experiment
/ Liang, Linbo (Manchester U. ; SLAC, SSRL) ; Saberi, Hossein (Manchester U. ; SLAC, SSRL) ; Xia, Guoxing (Manchester U. ; SLAC, SSRL) ; Farmer, John Patrick (CERN ; Munich, Max Planck Inst.) ; Pukhov, Alexander (Heinrich Heine U., Dusseldorf)
The oscillating relativistic electrons in the accelerating/focusing wakefields of plasma accelerators emit electromagnetic radiation known as betatron radiation (BR). The proton-driven plasma wakefield acceleration has been demonstrated in the Advanced Wakefield Experiment (AWAKE) at CERN; however, its accompanying radiation emission is less explored compared with those in the laser- and electron beam-driven plasma accelerators.

Development of the Self-Modulation Instability of a Relativistic Proton Bunch in Plasma
/ AWAKE Collaboration
Self-modulation is a beam-plasma instability that is useful to drive large-amplitude wakefields with bunches much longer than the plasma skin depth. We present experimental results showing that, when increasing the ratio between the initial transverse size of the bunch and the plasma skin depth, the instability occurs later along the bunch, or not at all, over a fixed plasma length, because the amplitude of the initial wakefields decreases. [...]
