  The Tevatron proton-antiproton collider at Fermilab operates at a centre of
mass energy of 1.96 TeV and is currently the only source for the production of
top quarks.
  Recent D0 results on the top quark's production cross section and its
properties such as mass, helicity of the W boson in its decay and branching
fraction B(t -> Wb) are presented, and probe the validity of the Standard
Model.
