Tech. ; Glasgow U.) ; Bruhwiler, David (RadiaSoft, Boulder) ; Cary, John (Tech-X, Boulder) ; Clarke, Christine (SLAC) ; Deng, Aihua (UCLA) ; Downer, Michael (Texas U.) ; Gessner, Spencer (CERN) et al.
Plasma accelerators support accelerating fields of 100's of GV/m over meter-scale distances and routinely produce femtosecond-scale, multi-kA electron bunches. The so called Trojan Horse underdense photocathode plasma wakefield acceleration scheme combines state-of-the-art accelerator technology with laser and plasma methods and paves the way to improve beam quality as regards emittance and energy spread by many orders of magnitude.

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.

Mono Energetic Beams from Laser Plasma Interactions
/ Geddes, Cameron G ; Cary, John R ; Esarey, Eric ; Leemans, Wim ; Nieter, Chet ; Schröder, Carl B ; Toth, Csaba ; Van Tilborg, Jeroen
A laser driven wakefield accelerator has been tuned to produce high energy electron bunches with low emittance and energy spread by extending the interaction length using a plasma channel. Wakefield accelerators support gradients thousands of times those achievable in RF accelerators, but short acceleration distance, limited by diffraction, has resulted in low energy beams with 100% electron energy spread.

Development of Advanced Models for 3D Photocathode PIC Simulations
/ Dimitrov, Dimitre ; Bruhwiler, David L ; Cary, John R ; Feldman, Donald ; Jensen, Kevin ; Messmer, Peter ; Stoltz, Peter
Codes for simulating photocathode electron guns invariably assume the emission of an idealized electron distribution from the cathode, regardless of the particular particle emission model that is implemented. The output of such simulations, a relatively clean and smooth distribution with very little variation as a function of the azimuthal angle, is inconsistent with the highly irregular and asymmetric electron bunches seen in experimental diagnostics. [...]
