| In this closeup of the central part of the CDF detector one can see various detector elements, as well as some of the cables and electronics used to collect information from the parts of the detector. The boxes mounted on the face of the orange structure contain electronics. The black semicircles to the right and left are the hadronic calorimeters. They detect particles known as hadrons by causing the particle to collide many times with iron plates. In these collisions, other particles are produced. These particles cross sheets of scintillating plastic where they give off small flashes of light. A measurement of the total amount of light measures the energy of the hadron. |
