CDF Detector (IMAGE) DOE/Fermi National Accelerator Laboratory Caption The CDF detector, about the size of a 3-story house, weighs about 6,000 tons. Its subsystems record the "debris" emerging from high-energy proton-antiproton collisions. The detector surrounds the collision point and records the path, energy and charge of the particles emerging from the collisions. This information can be used to find and determine the properties of the Xi-sub-b particle.
