Abstract
Ball, Melrose and Norman have raised a number of criticisms of a paper in which we suggest that stochastic Fermi acceleration, despite being currently out of favour, might offer a solution to the long-standing problem of the acceleration of cosmic rays to the highest observed energies. While the points made in criticism prompt the setting of the Fermi process in new perspective, they are found not to detract from the conclusion that smallscale (sub-parsec) regions of strong magnetic field (~lOµT) with random motion at speeds ~10-3 c could, in principle, account for acceleration to ~1020eV within the constraints imposed by current knowledge of the random component of the galactic magnetic field.
