متن کاملNumerical Studies of Self Modulation Instability in the Beam-driven Plasma Wakefield Experiments*
Proton beam-driven plasma wake-field acceleration has been proposed as a way to bring electrons to TeV energy range in a single plasma section. When a long proton bunch propagates into the plasma, this bunch splits into many small bunches. This phenomenon is known as a Self-Modulation Instability (SMI), and its characteristics depend on the ratio of bunch length and plasma wavelength. In this s...
متن کاملOptical Diagnostics for Plasma Wakefield Accelerators
The amount of spectral energy released by the plasma as visible light is proportional to the amount of energy loss of the beam, a simple beam independent diagnostic which is an ideal tool to help understand wake field plasma interaction is presented here. Continuum light emitted by particles through Cerenkov and/or optical transition processes also indicate the appearance of plasma particles tr...
متن کاملComputer simulations of ion motion in beam driven plasma wakefield accelerators
Issues related to plasma based acceleration using nonlinear wakefields are investigated. Nonlinear wakefields provide ideal linear focusing fields and radially independent accelerating fields which limit emittance growth and energy spread. When the accelerated charge is tightly focused the plasma ions can collapse thereby modifying the wakefields within the beam. We use computer simulations to ...
متن کاملEffects of ion motion in intense beam-driven plasma wakefield accelerators.
Recent proposals for using plasma wakefield accelerators (PWFA) as a component of a linear collider have included intense electron beams with densities many times in excess of the plasma density. The beam's electric fields expel the plasma electrons from the beam path to many beam radii in this regime. We analyze here the motion of plasma ions under the beam fields, and find for a proposed PWFA...
