Shaping trailing beams for beam loading via beam-induced-ionization injection at FACET
/ Amorim, Lígia Diana (SUNY, Stony Brook) ; Vafaei-Najafabadi, Navid (SUNY, Stony Brook) ; Emma, Claudio (SLAC) ; Clarke, Christine I (SLAC) ; Green, Selina Z (SLAC) ; Storey, Doug (SLAC) ; White, Glen (SLAC) ; O'Shea, Brendan (SLAC) ; Hogan, Mark J (SLAC) ; Yakimenko, Vitaly (SLAC) et al.
Recent progress in plasma based accelerator technology has demonstrated its ability to deliver high energy (GeV) beams in compact structures (centimeter to meter scale plasmas). Current developments of that technology are oriented toward producing beams with quality and energy spread comparable to those obtained using standard accelerating structures. [...]

Producing multi-coloured bunches through beam-induced ionization injection in plasma wakefield accelerator
/ Vafaei-Najafabadi, N (Stony Brook U.) ; Amorim, L D (Stony Brook U.) ; Adli, E (Oslo U.) ; An, W (UCLA) ; Clarke, C I (SLAC) ; Clayton, C E (UCLA) ; Corde, S (Palaiseau, Lab. Opt. Appl.) ; Gessner, S (CERN) ; Green, S Z (SLAC) ; Hogan, M J (SLAC) et al.
This paper discusses the properties of electron beams formed in plasma wakefield accelerators through ionization injection. In particular, the potential for generating a beam composed of co-located multi-colour beamlets is demonstrated in the case where the ionization is initiated by the evolving charge field of the drive beam itself.

Betatron radiation and emittance growth in plasma wakefield accelerators
/ San Miguel Claveria, P (Palaiseau, Lab. Opt. Appl.) ; Adli, E (Oslo U.) ; Amorim, L D (Stony Brook U.) ; An, W (UCLA) ; Clayton, C E (UCLA) ; Corde, S (Palaiseau, Lab. Opt. Appl.) ; Gessner, S (CERN) ; Hogan, M J (SLAC) ; Joshi, C (UCLA) ; Kononenko, O (Palaiseau, Lab. Opt. Appl.) et al.
Beam-driven plasma wakefield acceleration (PWFA) has demonstrated significant progress during the past two decades of research. The new Facility for Advanced Accelerator Experimental Tests (FACET) II, currently under construction, will provide 10 GeV electron beams with unprecedented parameters for the next generation of PWFA experiments.

Plasma wakefield acceleration experiments at FACET II
/ Joshi, C (UCLA) ; Adli, E (Oslo U.) ; An, W (UCLA) ; Clayton, C E (UCLA) ; Corde, S (Palaiseau, Lab. Opt. Appl.) ; Gessner, S (CERN) ; Hogan, M J (SLAC) ; Litos, M (Colorado U.) ; Lu, W (Tsinghua U., Beijing, Dept. Eng. Phys.) ; Marsh, K A (UCLA) et al.
During the past two decades of research, the ultra-relativistic beam-driven plasma wakefield accelerator (PWFA) concept has achieved many significant milestones. These include the demonstration of ultra-high gradient acceleration of electrons over meter-scale plasma accelerator structures, efficient acceleration of a narrow energy spread electron bunch at high-gradients, positron acceleration using wakes in uniform plasmas and in hollow plasma channels, and demonstrating that highly nonlinear wakes in the 'blow-out regime' have the electric field structure necessary for preserving the emittance of the accelerating bunch.

Measurement of transverse wakefields induced by a misaligned positron bunch in a hollow channel plasma accelerator
/ Lindstrøm, C.A. (Oslo U.) ; Adli, E. (Oslo U.) ; Allen, J.M. (SLAC) ; An, W. (UCLA, Los Angeles (main)) ; Beekman, C. (Palaiseau, Lab. Opt. Appl.) ; Clarke, C.I. (SLAC) ; Clayton, C.E. (UCLA, Los Angeles (main)) ; Corde, S. (Palaiseau, Lab. Opt. Appl.) ; Doche, A. (Palaiseau, Lab. Opt. Appl.) ; Frederico, J. (SLAC) et al.
Hollow channel plasma wakefield acceleration is a proposed method to provide high acceleration gradients for electrons and positrons alike: a key to future lepton colliders. However, beams which are misaligned from the channel axis induce strong transverse wakefields, deflecting beams and reducing the collider luminosity. [...]
