Hosing instability in the blow-out regime for plasma-wakefield acceleration.
نویسندگان
چکیده
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. Lett. 67, 991 (1991)10.1103/PhysRevLett.67.991] which is strictly valid for preformed channels. Particle-in-cell simulations agree with this new theory, which predicts less hosing growth than found by the hosing theory of Whittum et al.

Plasma Wave Acceleration of Electron in Bubble Regime in Presence of a Planar Wiggler
The plasma wave acceleration of electron in the bubble regime is investigated in a new configuration containing a planar wiggler. The space-charge field of the laser-created ion channel can focuse and stabilize the electron trajectory to guide it toward the acceleration region. The high-gradient plasma wave field can resonantly accelerate the trapped electron to higher energies in the presence ...
متن کاملExperimental Plasma Wake-field Acceleration Project at the Vepp-5 Injection Complex
The project of an experimental facility based on the VEPP-5 injection complex is described. Due to a good quality of electron or positron beams and special beam preparation system, the facility opens several possibilities for studies of the plasma wakefield acceleration: high peak beam currents, arbitrary beam profiles, long term beamplasma interaction (up to the full driver depletion), and pre...
متن کاملSelf-modulation instability of a long proton bunch in plasmas.
An analytical model for the self-modulation instability of a long relativistic proton bunch propagating in uniform plasmas is developed. The self-modulated proton bunch resonantly excites a large amplitude plasma wave (wakefield), which can be used for acceleration of plasma electrons. Analytical expressions for the linear growth rates and the number of exponentiations are given. We use full th...

1 We present the status of transverse instability studies in the 2 plasma-wakefield acceleration experiments at FACET. PIC sim3 ulations indicate that a head-tail tilt on the electron beam as it 4 enters to the plasma may lead not only to hosing but also a co5 herent transverse motion of the system beam and plasma bubble. 6 The FACET dump line is equipped with a Cherenkov light based 7 spectrom...

We present the status of transverse instability studies in the plasma-wakefield acceleration experiments at FACET. PIC simulations indicate that a head-tail tilt on the electron beam as it enters to the plasma may lead not only to hosing but also a coherent transverse motion of the system beam and plasma bubble. The FACET dump line is equipped with a Cherenkov light based spectrometer which can...
