The Start of RUN II at CDF
  After a hiatus of almost 6 years and an extensive upgrade, Tevatron, the world largest proton--antiproton collider, has resumed the operation for the so called RUN II. In this paper we give a brief overview of the many new features of the Tevatron complex and of the upgraded CDF experiment, and show the presently achieved detector performances as well as highlights of the RUN II physics program in the beauty and electroweak sector.
