Test of the Electron Hose Instability in the E157 Experiment*
The E157 experiment is designed to demonstrate highgradient Plasma Wake Field Acceleration over a significant length. It has been suggested that the electron hose instability of the drive beam will degrade the performance of this experiment because the hosing tailelectrons will not fully sample the highest acceleration field. In this paper a parasitic experiment designed to test the extent of t...
متن کاملHellinger and Matsumoto : Oblique Alfvén Fire Hose a 5 - 10 , 521
Two instabilities could take place in plasma with a bi-Maxwellian proton distribution function with Tp‖ > Tp⊥, where Tp‖ and Tp⊥ are proton temperatures, parallel and perpendicular, respectively, to the background magnetic field. The first instability is the fire hose (or whistler fire hose), generating low-frequency whistler waves at parallel propagation. We found a new, second instability, th...
متن کاملIon-hose Instability in a Long-pulse Accelerator
The ion-hose instability is a transverse electrostatic instability which occurs on electron beams in the presence of a low-density ion channel. In the DARHT-2 accelerator, the 2 kA, 2 microsecond beam pulse produces an ion channel through impact ionization of the residual background gas ( 1:5 10 7 torr average). A calculation of the linear growth by R. J. Briggs indicated that the instability c...
متن کاملFirst Results from the Electron Hose Instability Studies in Facet∗
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...
متن کاملInhomogeneous Flows of Complex Fluids: Mechanical Instability Versus Non-Equilibrium Phase Transition
We briefly review and re-interpret recent experiInental results on shear-induced inhoInogeneous flows in coInplex fluids. These are usually explained in terIns of aInechanical instability of the non-linear flow regiIne. However, in at least two respects, the robustness of the two-state banded-flow regiIne and the kinetics of band forInation under shear, they present striking analogies with ordi...
