Elevating electron energy gain and betatron X-ray emission in proton-driven wakefield acceleration / Saberi, Hossein (Manchester U. ; Daresbury) ; Xia, Guoxing (Manchester U. ; Daresbury) ; Liang, Linbo (Manchester U. ; Daresbury) ; Farmer, John Patrick (CERN ; Munich, Max Planck Inst.) ; Pukhov, Alexander (Heinrich Heine U., Dusseldorf)
The long proton beams present at CERN have the potential to evolve into a train of microbunches through the self-modulation instability process. The resonant wakefield generated by a periodic train of proton microbunches can establish a high acceleration field within the plasma, facilitating electron acceleration. [...]

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.

Acceleration of an Electron Bunch with a Non–Gaussian Transverse Profile in Proton-Driven Plasma Wakefield / Liang, Linbo (Manchester U. ; Daresbury) ; Xia, Guoxing (Manchester U. ; Daresbury) ; Pukhov, Alexander (Heinrich Heine U., Dusseldorf) ; Farmer, John Patrick (CERN ; Munich, Max Planck Inst.)
Beam-driven plasma wakefield accelerators typically use the external injection scheme to ensure controllable beam quality at injection. However, the externally injected witness bunch may exhibit a non-Gaussian transverse density distribution. [...]

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. [...]

The spectroscopy of betatron radiation from the focusing plasma column can work as a powerful non-invasive beam diagnostic method for plasma wakefield acceleration experiments such as the AWAKE. [...]

Quasi-stable injection channels in a wakefield accelerator / Wiltshire-Turkay, Mara (Heinrich Heine U., Dusseldorf) ; Farmer, John P (Heinrich Heine U., Dusseldorf) ; Pukhov, Alexander (Heinrich Heine U., Dusseldorf)
Particle-driven plasma-wakefield acceleration is a promising alternative to conventional electron acceleration techniques, potentially allowing electron acceleration to energies orders of magnitude higher than can currently be achieved. In this work we investigate the dependence of the energy gain on the position at which electrons are injected into the wake. [...]
