Abstract

An analysis is made of the cosmic ray energy spectrum expected from
supernova remnant acceleration of cosmic rays for energies below the
well known knee at 3 x 10(6) GeV. Two models are considered; that based
on the single-shock acceleration model of Axford (1981 Pi-oc 17th Int.
Cosmic Ray Conf. (Paris) 12 155) with associated diffusion and Galactic
leakage is preferred. A local recent supernova, with a statistical
probability as high as similar to 15-50%, is adequate to explain the
features of the knee, in accord with our previous arguments (e.g.
Erlykin and Wolfendale 1998 Astropart Phys. 8265). Such a supernova
needs to be closer than 500 pc to the Earth and younger than 110 kyr.
