22. Energy-Chirp Compensation in a Laser Field Accelerator

Author

Döpp A, Thaury C, Guillaume E, Massimo F, Lifschitz A, Andriyash I, Goddet J-P, Tazsfi A, Ta Phuoc K, and Malka V

Abstract

The energy spread in laser wakefield accelerators is primarily limited by the energy chirp introduced during the injection and acceleration processes. Here, we propose the use of longitudinal density tailoring to reduce the beam chirp at the end of the accelerator. Experimental data sustained by quasi-3D particle-incell simulations show that broadband electron beams can be converted to quasimonoenergetic beams of ≤ 10% energy spread while maintaining a high charge of more than 120 pC. In the linear and quasilinear regimes of wakefield acceleration, the method could provide even lower, subpercent level, energy spread. &nbsp

33. Electron Rephasing in a Laser-Wakefield Accelerator

Author

Guillaume, E., Döpp, A., Thaury, C., Ta Phuoc, K., Lifschitz, A., Grittani, G., Goddet, J.-P., Tafzi, A., Chou, S.-W., Veisz, László, Malka, V., Guillaume, E., Döpp, A., Thaury, C., Ta Phuoc, K., Lifschitz, A., Grittani, G., Goddet, J.-P., Tafzi, A., Chou, S.-W., Veisz, László, and Malka, V.

Abstract

An important limit for energy gain in laser-plasma wakefield accelerators is the dephasing length, after which the electron beam reaches the decelerating region of the wakefield and starts to decelerate. Here, we propose to manipulate the phase of the electron beam in the wakefield, in order to bring the beam back into the accelerating region, hence increasing the final beam energy. This rephasing is operated by placing an upward density step in the beam path. In a first experiment, we demonstrate the principle of this technique using a large energy spread electron beam. Then, we show that it can be used to increase the energy of monoenergetic electron beams by more than 50%.

Abstract

The energy gain in laser wakefield accelerators is limited by dephasing between the driving laser pulse and the highly relativistic electrons in its wake. Since this phase depends on both the driver and the cavity length, the effects of dephasing can be mitigated with appropriate tailoring of the plasma density along propagation. Preceding studies have discussed the prospects of continuous phaselocking in the linear wakefield regime. However, most experiments are performed in the highly nonlinear regime and rely on self-guiding of the laser pulse. Due to the complexity of the driver evolution in this regime, it is much more difficult to achieve phase locking. As an alternative, we study the scenario of rapid rephasing in sharp density transitions, as was recently demonstrated experimentally. Starting from a phenomenological model, we deduce expressions for the electron energy gain in such density profiles. The results are in accordance with particle-in-cell simulations, and we present gain estimations for single and multiple stages of rephasing. [ABSTRACT FROM AUTHOR]
