A 3-day workshop on `Cosmic ray dynamics: from turbulent to Galactic-scale magnetic fields' in Copenhagen, 2-4 September 2004.Background and Purpose
The dynamics of cosmic ray particles crucially depends on the detailed structure of interstellar magnetic fields over a broad range of scales, from the dissipation scale of interstellar turbulence up to the dimension of the Galactic halo. The intermittent (filamentary) nature of turbulent magnetic fields, recently revealed by MHD simulations, should affect significantly the diffusivity of cosmic ray particles, whereas understanding the global symmetry and strength of the global magnetic field in the Galactic halo is essential for the clarification of the origin of high-energy cosmic rays. On the other hand, cosmic rays significantly affect interstellar gas motions, and therefore the system of cosmic rays, magnetic fields and gas should be studied self-consistently. The need for the self-consistent studies has been long appreciated, but only now we are in a position to start such a work. An important factor here is the advent of the realistic models of interstellar medium driven by supernovae, that include magnetic fields. The topic is important for researchers in (1) cosmic ray and particle astrophysics, (2) physics of interstellar medium, (3) radio astronomy, (4) astrophysical magnetohydrodynamics.Scientific Organizing Committee
