Transport of magnetic turbulence in the vicinity of Supernova Remnant shock fronts — •Robert Brose^1,2 and Igor Telezhinsky^2,3 — ¹Humboldt-Universität zu Berlin, Institute of Physics, Unter den Linden 6, 10099 Berlin, Germany — ²DESY, Platanenallee 6, 15738 Zeuthen, Germany — ³University of Potsdam, Institue of Physics & Astronomy, Karl-Liebknecht-Straße 24/25, 14476 Potsdam, Germany

To model the acceleration of cosmic rays in Supernova Remnants, we solve a time-dependent transport equation for magnetic turbulence accounting for advection and cascading of waves traveling in upstream or downstream direction. This is combined with prior simulations by Telezhinsky, et al., which modeled CR acceleration by solving the CR transport equation in a test-particle approach combined with 1-D hydrodynamical simulations of the Remnant evolution. This way we account for the amplification of magnetic turbulence, which is thought to be needed to confine particles close enough to the shock to participate in the acceleration process. Both transport equations are coupled via the diffusion coefficient respectively the energy density of the magnetic turbulence and the growth rates. Here first self-consistent particle and turbulence spectra for type Ia Supernova Remnants are going to be presented.
