Description
Laser-plasma electron beams are known for their large divergence and energy spread while having ultra-short bunches, which differentiate them from standard RF accelerated beams.
To study the laser-plasma beam dynamics and to design a transport line, simulations with CODAL [1], a code developed by SOLEIL in collaboration with IJCLab, have been used. CODAL is a 6D 'kick' tracking code based on the symplectic integration of the local hamiltonian for each element of the lattice. CODAL also includes collective effects simulations such as space charge, wakefield and coherent synchrotron radiation.
To validate the studies in the framework of Laser-Plasma Acceleratior developpement, results from CODAL have been compared to TraceWin [2], a well-known tracking code developed by CEA.
The comparison has been made using the outcome of Laser WakeField Acceleration (LWFA) particle-in-cell simulations as initial start particle coordinates from a case study of PALLAS project, a Laser-Plasma Accelerator test facility at IJCLab.
