We use nonlinear kinetic theory to study
the remnant dynamics and the particle acceleration as well as the
properties of the nonthermal emission from
the supernova remnant SN 1006. The known range of astronomical
parameters is examined to determine whether it
encompasses the
existing synchrotron emission data. Given the present-day spatial extent
and expansion rate of the object, it is shown that the hadronic
gamma-ray flux is very sensitive to the ambient gas density and that the existing HESS upper limit requires
cm-3. The strength of the amplified magnetic field downstream
of the
shock is about 150 μG.
