Description
The development of advanced acceleration methods with a large acceleration gradient, much larger than achieved in conventional radio frequency accelerators, is necessary to reach a TeV-energy range for future electron-positron colliders. One of the possible approaches is based on the multistage acceleration in the wakefields generated in plasma by relativistic-intense femtosecond laser pulses.
The laser wakefield acceleration of short electron bunches to multi-GeV energies with small emittance and energy spread is modelled and analyzed. Trapping and acceleration of short electron bunches externally injected into the wakefields generated by intense femtosecond laser pulse in plasma channel are optimized. The influence of the laser nonlinear dynamics and loading effect (self-action of the bunch charge) to the bunch final energy and energy spread of the accelerated electrons is investigated. The restrictions to the charge of accelerated electron bunch caused by the require of its small energy spread are determined [1].
