Abstract: An integrated simulation approach fully based on the particle-in-cell (PIC) model is proposed, which involvesboth fast-particle generation via laser solid-density plasma interaction and transport and energy deposition of theparticles in extremely high-density plasma. It is realized by introducing two independent systems in a simulation,where the fast-particle generation is simulated by a full PIC system and the transport and energy depositioncomputed by a second PIC system with a reduced field solver. Data of the fast particles generated in the fullPIC system are copied to the reduced PIC system in real time as the fast-particle source. Unlike a two-regionapproach, which takes a single PIC system and two field solvers in two plasma density regions, respectively, thepresent one need not match the field solvers since the reduced field solver and the full solver adopted respectivelyin the two systems are independent. A simulation case is presented, which demonstrates that this approach canbe applied to integrated simulation of fast ignition with real target densities, e.g., 300 g/cm3.
