We investigate quasi-linear theory of ion acceleration at Earth's quasi-parallel bow shock using Cluster magnetic field and particle measurements during an upstream diffuse ion event (February 18, 2003). Simultaneous magnetic field power spectra far upstream obtained by ACE show that the interplanetary fluctution level in the region of resonant frequencies was orders of magneitude lower than near the bow shock, so that the fluctuations near the bow shock were excited by backstreaming ions. In particular, we determine the energetic ion spatial profile, the dependence of the upstream ion scalelength upon energy, the behavior of the energetic ion anisotropy upstream and downstream of the shock, the spatial scale lenghts of the low frequency upstream waves that resonate with them, and the dependence of the integrated wave energy density upon the ion energy density at the shock.
