The CDF Forward Detector upgrade project was designed to enhance
the capabilities for diffractive physics at the Tevatron. It consists of a
Roman Pot spectrometer to detect leading antiprotons, a set of counters near
and around the beam-pipe to reject the non-diffractive event contamination
to the data sample, and two Miniplug calorimeters to measure the event
energy flow in the very forward rapidity region. In the novel design of the
Miniplugs, a lead/liquid-scintillator is read out by wave-length shifting
fibers arranged in a flexible tower geometry and relatively short depth
allows calorimetric tracking. Performance of the Forward Detectors during
the first two years of operation in Run II with colliding proton-antiproton
beams at sqrt s = 1.96 TeV, as well as the first results obtained, are
discussed. A measurement of the antiproton momentum loss using the Forward
Detectors is also presented.
