The bunch length decreases substantially in
the process of trapping
3-D simulations are in a good agreement with 1-D
theory for injected electron bunches of small
radius
1-D simulations confirm simple analytical
predictions
For the velocity of injected electrons
4
Energy spread decreases
substantially at the end of accelerating phase
in accordance with the theory for injected
electron bunches of small radius

Characterization of the trapping and acceleration
stages
Bunch injection into the maximum of the wakefield
potential
Bunch injection in front of the laser pulse

For the above example

Stable multistage acceleration of
compressed electron bunches
with low emittance
and energy spread
