Energy loss of a high charge bunched electron beam in plasma: Simulations, scaling, and accelerating wakefields

061302-1 The energy loss and gain of a beam in the nonlinear, ‘‘blowout’’ regime of the plasma wakefield accelerator, which features ultrahigh accelerating fields, linear transverse focusing forces, and nonlinear plasma motion, has been asserted, through previous observations in simulations, to scale linearly with beam charge. Additionally, from a recent analysis by Barov et al., it has been co...

Electron cloud simulations: beam instabilities and wakefields

121002-1 HEADTAIL is a simulation program developed at CERN which is aimed at studying the single-bunch instability arising from the interaction on successive turns of a single bunch with the cloud generated by the previous bunches. The code includes chromaticity, space charge tune spread, broad-band impedance, and detuning with amplitude for more realistic simulation. Examples of application a...

Review of Beam Driven Plasma Wakefield Accelerators

The current status of the beam-driven plasma wakefield accelerators is reviewed.

Calculation of wakefields in a 17 GHz beam-driven photonic band-gap accelerator structure

Breakdown limits on Gigavolt-per-meter electron-beam-driven wakefields in dielectric structures.

First measurements of the breakdown threshold in a dielectric subjected to GV/m wakefields produced by short (30-330 fs), 28.5 GeV electron bunches have been made. Fused silica tubes of 100 microm inner diameter were exposed to a range of bunch lengths, allowing surface dielectric fields up to 27 GV/m to be generated. The onset of breakdown, detected through light emission from the tube ends, i...
