  The 1992-1995 running of the Fermilab Tevatron ended with many important
physics goals accomplished, including the discovery of the top quark, and the
anticipation of many further questions to be answered in the future. After many
upgrades to the detector and to the accelerator complex, Run II began in April
2001. First results obtained by the Collider Detector at Fermilab (CDF)
collaboration from the analysis of early Tevatron Run II data are reported
here. They fall in two categories: a number of measurements have been performed
with the primary goal of establishing detector performance and physics
potential. Another set of measurements make use of completely new capabilities
of the upgraded detector, thus allowing for competitive results with a modest
amount of integrated luminosity.
