The first view shows the entire SLD Detector, approximately 10 meters high. The green lines radiating from the center are particle tracks seen by the Vertex Detector and Drift Chamber. The colored boxes are energy deposits seen in the Liquid Argon Calorimeter and Warm Iron Calorimeter.

The second view shows a zoom in on the center of the same event. The squares represent individual Charged Coupled Devices (CCDs) within the Vertex Detector (SLD's Vertex Detector is the most precise device of its kind in the world). The Diamonds on these squares show individual hit pixels within the CCDs.

The third view continues our zoom in on the same event. Using the precise position information from the Drift Chamber and Vertex Detector, the tracks are extrapolated inwards. By seeing where these tracks intersect, we can tell where the quarks, too short-lived to be seen directly by any detector, decayed into the particles that we detect. All of the red tracks are thought to have come from the decay of one quark, all of the blue from another, and so forth.
