Optical Injection into Laser Wake Field Accelerators / Cary, John R ; Bruhwiler, David L ; Esarey, Eric ; Geddes, Cameron G R ; Giacone, Rodolfo ; Leemans, Wim ; Nieter, Chet
The accelerating gradient of laser-generated wake fields in plasmas can be orders of magnitude greater than the gradients obtainable in traditional, rf structures. One of the hurdles to overcome on the road to practical utilization of said plasma wake fields for production of high energy particles is the creation of quality beams having significant charge, low emittance, and narrow energy spread.

Simulations of Laser Pulse Coupling and Transmission Efficiency in Plasma Channels / Giacone, Rodolfo ; Bruhwiler, David L ; Cary, John R ; Dimitrov, Dimitre ; Esarey, Eric ; Geddes, Cameron G R ; Leemans, Wim ; Messmer, Peter
Optical guiding of the laser pulse in a laser wakefield accelerator (LWFA) via plasma channels can greatly increase the interaction length and, hence, the maximun energy of trapped electrons.* Energy efficient coupling of laser pulses from vacuum into plasma channels is very important for optimal LWFA performance. We present 2D particle-in-cell simulations of this problem using the VORPAL code.** Some of the mechanisms considered are enhanced leakage of laser energy transversely through the channel walls, enhanced refraction due to tunneling ionization of neutral gas on the periphery of the gas jet, ionization of neutral gas by transverse wings of the laser pulse and effect of the pulse being off axis of the channel [...]
