  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
selection of functions of merit used to grade generated electron beams is
discussed. Among the significant number of configurations, two specific working
points are presented in details. All data generated are left open to the
scientific community for further study and optimisation.
