  Two Miniplug calorimeters, designed to measure the energy and lateral
position of particles in the forward pseudorapidity region of 3.6<|\eta |<5.1,
have been installed as part of the CDF upgraded detector for Run II at the
Tevatron. Proton-antiproton beams are colliding at $\sqrt{s}$=1.96 TeV. One
year after installation, Miniplug detector performance and first results are
presented.
