Methods for the calculation of laser tunneling ionization in explicit particle-in-cell codes used for modeling laser–plasma interactions are compared and validated against theoretical predictions. Improved accuracy is obtained by using the direct current form for the ion-ization rate. Multi level ionization in a single time step and energy conservation have(More)
Keywords: Plasma accelerator Laser–plasma acceleration Laser wakefield acceleration PIC Envelope model a b s t r a c t Simulation of laser–plasma accelerator (LPA) experiments is computationally intensive due to the disparate length scales involved. Current experiments extend hundreds of laser wavelengths transversely and many thousands in the propagation(More)
