A simulation for electron trapping and acceleration in parabolic density profile and ongoing experimental plan

It is known that as a laser wakefield passes through a downward density transition in a plasma some portion of the background electrons are trapped in the laser wakefield and the trapped electrons are accelerated to relativistic high energies over a very short distance. In this study, by using a two-dimensional particle-in-cell (PIC) simulation, we suggest an experimental scheme that can manipulate electron trapping and acceleration across a parabolic plasma density channel, which is easier to produce and more feasible to apply to the laser wakefield acceleration experiment. Also, we present a brief ongoing experimental research plan by using the newly developed high power femtosecond laser in KERI.
