The CDF (Collider Detector experiment at Fermilab) is an international collaboration of about 500 Physicists (from about 30 American universities and National laboratories, etc, plus also from about 30 groups from universities and national laboratories from Italy, Japan, UK, Canada, Germany, Spain, Russia, Finland, France, Taiwan, Korea, Switzerland, etc.). We have built the 100-ton CDF detector (about 40' high by 40' x 40' base at the Fermilab Tevatron collider (colliding High energy-- approximately 1000 Gev or 1 TeV--protons with anti-protons) with the goal of measuring exceptional events out of the billions of collisions to

  • Look for the production of New Physics
  • Measure and study the production and decay of heavy particles such as the Top and Bottom Quarks, and the W and Z bosons.
  • Measure and study the production of High Energy jets and photons
  • Other studies such as diffraction, etc.

HIGH ENERGY PROTONS AND ANTIPROTONS COLLISIONS--The tevatron collider, currently the highest energy collider in the world, studies the collision of 1000 GeV protons with 1000 GeV anti-protons. As you may know, Einstein's special relativity says that as a particle gets more energetic, it gets more massive (somewhat related to the famous E = M C Squared formula). The Tevatron is an accelerator which uses alternating electric current (in special RF Cavities) to speed up the protons (and antiprotons--afterwards, I will use the word protons to mean both protons and antiprotons) to within a small fraction of the speed of light, thus making these energetic protons having a mass that is more than 1000 times the mass of a proton at rest !!!! The Magnets around the circular Tevatron bends the protons into a 4 miles circumferance ring thus enabling the RF cavities to repeatedly speed up the protons. Once the Proton reaches the energy of about 1000 GeV (G mean Giga of 10**9, and T means Teva 10**12), the magnet in the ring makes the beam of protons collide with the beam of antiprotons and continue for up to 30 hours, until the proton beams are dissipated.
