[PEM17-08] Long-term PIC simulations of relativistic shocks using the magic CFL method
Keywords:PIC simulation, relativistic shocks, particle acceleration
Using the newly found stability property of the NCI, we successfully solved long-term evolutions of relativistic collision-less shocks. For relativistic, un-magnetized shocks in pair plasmas, we found that magnetic field turbulence generated by the Weibel instability saturated at much larger levels than those found in the previous studies. As results, particles’ maximum energy increased linearly in time with the energy spectral slope γ−1.8 , which compares with the previously-reported relation as γmax ∝√t with γ−2.4.
