After the successful Run I of the Tevatron (1992-1996), with the
top quark discovery, both CDF and D0 experiments were extensively upgraded
to meet the challenges of the Tevatron Run II collider. The energy of p anti-p
collisions at the Tevatron was increased from s**(1/2) = 1.8 TeV to s**(1/2) =
1.96 TeV. tt-bar production cross section is expected to increase by a
factor of ~ 30%. Major upgrades in the Tevatron accelerator chain will
increase the Run II instantaneous luminosity: the goal is to achieve L = 5 -
20 x 1031 cm2 s-1 while the highest luminosity reached up to now
(September 2003) is 5.2 x 1031 cm2 s-1.
