Plasma-wakefield acceleration of a positron beam.
Plasma-wakefield excitation by positron beams is examined in a regime for which the plasma dynamics are highly nonlinear. Three dimensional particle-in-cell simulations and physical models are presented. In the nonlinear wake regime known as the blowout regime for electrons, positron wakes exhibit an analogous "suck-in" behavior. Although analogous, the two wakefield cases are quite different i...
متن کاملPlasma wakefield acceleration experiments at FACET II
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 highgradients, positron acceleration us...
متن کاملPlasma wakefield acceleration experiments at FACET
FACET—Facilities for Accelerator science and Experimental Test beams at SLAC—will provide high-energy-density electron and positron beams with peak currents of roughly 20 kA that will be focused down to a 10μm× 10μm transverse spot size at an energy of ∼23GeV. With FACET, the SLAC linac will support a unique program concentrating on second-generation research in plasma wakefield acceleration. T...
متن کاملCosmic Plasma Wakefield Acceleration
Recently we proposed a new cosmic acceleration mechanism which was based on the wakefields excited by the Alfven shocks in a relativistically flowing plasma. In this paper we include some omitted details, and show that there exists a threshold condition for transparency below which the accelerating particle is collision-free and suffers little energy loss in the plasma medium. The stochastic en...
متن کاملNovel Module for Plasma Wakefield Acceleration of a Positron Beam
A novel approach for studying positron acceleration physics without an external positron source is developed. This scheme uses an e beam to both create positrons in a target before the plasma and to excite the wake that accelerates these positrons. 2-D PIC simulations show that ultra-short e bunches can be focused and accelerated.
