Energy Transfer in the Plasma Wake-Field Accelerator

The Plasma Wake Field Accelerator*

A new scheme of electron acceleration, employing relativistic electron bunches in a cold plasma, is analyzed. The wake field of a leading bunch is derived in a single-particle model. We then extend the model to include finite bunch length effect. In particular, we discuss the relation between the charge distributions of the driving bunch and the energies transformable to the trailing electrons....

On Energy Transfer in the Plasma Wake Field

The transfer of energy from the driving beam to the trailing beam in the plasma wake field accelerator is studied in computer simulations. We show that with an asymmetric current distribution in the driving bunch, trailing particles can gain energies up -to 4 1 + k2Z2Aymc2 P , where 2 is the bunch length, and A,ymc2 the average energy loss of driving electrons. Due to the relative phase slippag...

A Comparison of the Plasm-a Beat Wave Accelerator and the Plasma Wake Field Accelerator*

In this paper we compare the Plasma Beat Wave Accelerator and the Plasma Wake Field Accelerator. We show that the electric fields in the plasma for both schemes are very similar, and thus the dynamics of the driven beams are very similar. The differences appear in the parameters associated with the driving beams. In particular to obtain a given accelerating gradient, the Plasma Wake Field Accel...

Particle Beam Stability in the Hollow Plasma Channel Wake Field Accelerator

The electromagnetic wake field response of a hollow plasma channel to a driver (laser or charged particle beam) of arbitrary velocity is derived. The dispersion and loss factors of excited fundamental and higher order azimuthal modes are computed. Growth rates for beam breakup instabilities are calculated and beam transport is studied. External focusing is shown to provide a method of controlli...
