Wake field in dielectric acceleration structures.
In this study we present a general approach for the analysis of the wake field of a point charge moving in a vacuum tunnel bored in dielectric material that is uniform in the direction parallel to the motion of the bunch. In the transverse direction the structure surrounding the dielectric may have arbitrary geometry. A quasianalytic expression that relates the decelerating force with the first...
متن کاملStochastic wake field particle acceleration in Gamma-Ray Bursts
Gamma-Ray Burst (GRB) prompt emission can, for specific conditions, be so powerful and short-pulsed to strongly influence any surrounding plasma. In this paper, we briefly discuss the possibility that a very intense initial burst of radiation produced by GRBs satisfy the intensity and temporal conditions to cause stochastic wake-field particle acceleration in a surrounding plasma of moderate de...
متن کاملPlasma - Pulse - Acceleration Experiments
This paper gives recent results of experiments with a coaxial Plasma-Pulse-Accelerator (PPA). Discharging a capacitor bank into the PPA more than 80 % of the stored energy could be transferred from the electrical circuit into the plasma. Accelerating masses of 10 g to velocities of 1020 m/s overall efficiencies of 22 % were achieved. A 3 g mass could be accelerated in the same PPA to 2000 m/s; ...
متن کاملLaser wake-field acceleration and optical guiding in a hollow plasma channel
The accelerating and focusing wake fields that can be excited by a short laser pulse in a hollow underdense plasma are examined. The evacuated channel in the plasma serves as an optical fiber to guide the laser pulse over many Rayleigh lengths. Wake fields excited by plasma current at the edge of the channel extend to the center where they may be used for ultrahigh gradient acceleration of part...
متن کاملEffect of the bubble deformation in the3D nonlinear laser wake-field acceleration
A new analytical approach for bubble deformation was used for optimization of the electron acceleration in the 3D highly nonlinear laser wake-field regime. Injection of the electron bunch with initial velocity in the bubble was considered in the inhomogeneous plasma with linearly density ramp. The researchers show that deformation of the bubble shape has an efficient role on the trapping of the...
