A method for the optimisation and advanced studies of a laser-plasma electron injector is
presented, based on a truncated ionisation injection scheme for high quality beam
production. The SMILEI code is used with laser envelope approximation and a low number
of particles per cell to reach computation time performances enabling the production of a
large number of accelerator configurations. The developed and tested workflow is a possible
approach for the production of large dataset for laser-plasma accelerator optimisation. A …

A method for the optimisation and advanced studies of a laser-plasma accelerator electron
source [1] is presented. In the following we focus on the specific case of a laserplasma
injector based on ionisation injection [4, 5, 6] for high quality beam production. We use the
Particle-in-Cell (PIC) SMILEI code [2] with envelope approximation [3] for the laser and a low
number of particles per cell allowing to reach computation time performances enabling the
production of a large number of data set. Various operation mode of the laser-plasma …
