Abstract

In this thesis is a model investigated for the acceleration of UHECR's in the magnetar wind. First, the configuration of the field lines of a magnetar is examined using pulsar models. Furthermore the concept of the plasma wakefield acceleration using Alfven waves and what the conditions are for optimal acceleration is examined. Using the model we can derive a maximum energy, a power law spectrum and a ux. The maximum energy ranges from an energy of 10^19 eV on a lower limit and of 10^27 eV on a upper limit. We find a power law of e^-2 and a flux of 1:6 * 10^-8 UHECR / m2 /year for a particle with energies greater than 1020 eV. The power law is in line with observations. The flux number is also in line with observations. Estimates on the flux number are very rough, ber are very rough, so we cannot make some final conclusions on that.
