Hosing Instability Suppression in Self-Modulated Plasma Wakefields

Hosing instability in the blow-out regime for plasma-wakefield acceleration.

The electron hosing instability in the blow-out regime of plasma-wakefield acceleration is investigated using a linear perturbation theory about the electron blow-out trajectory in Lu et al. [in Phys. Rev. Lett. 96, 165002 (2006)10.1103/PhysRevLett.96.165002]. The growth of the instability is found to be affected by the beam parameters unlike in the standard theory Whittum et al. [Phys. Rev. Le...

Self-consistent chaos in the beam-plasma instability

The effect of self-consistency on Hamiltonian systems with a large number of degrees of freedom is investigated for the beam-plasma instability using the single-wave model of O’Neil, Winfrey, and Malmberg. The single-wave model is reviewed and then rederived within the Hamiltonian context, which leads naturally to canonical action-angle variables. Simulations are performed with a large (1 04) n...

Ultrafast XUV emission from laser wakefields in underdense plasma

It is shown that a laser wakefield driven in the highly nonlinear regime or the wave-breaking regime in underdense plasma can emit ultrabroad-band bright extreme ultraviolet (XUV) radiation pulses, which are as short as a few hundreds of attoseconds in one-dimensional simulations and a few femtoseconds in multi-dimensional cases. The emission is caused by a transverse current sheet co-moving wi...

Study of Laser Injection of Electrons into Plasma Wakefields

A proposed laser-plasma based electron source [1] using laser triggered injection of electrons is examined. The source generates ultrashort electron bunches by dephasing background plasma electrons undergoing fluid oscillations in a plasma wake. The plasma electrons are dephased by colliding two counter-propagating laser pulses. Laser intensity thresholds for trapping and optimal wake phase for...
