The Collider Detector Facility (CDF)

The Tevatron at Fermilab has two detector complexes referred to as CDF and D0. Both are enormous detector arrays weighing some 5000 tons and standing three stories in height. 费米实验室的Tevatron有两组探测器，分别称为CDF和D0。它们都是巨大的探测器阵列，重量约为5000吨，高度约为三层。 This detector was involved in the discovery of the top quark in 1995. 这个探测器参与了1995年顶夸克的发现。

The schematic illustration above shows that the enormous collection of detection hardware is arranged so that the particle beams enter from opposite directions along its central axis. The detectors are arranged around the collision area in to attempt to detect and measure all fragments of the collisions. The logic is somewhat like that for a linear detector array, except that it is wrapped around the beam path to detect particles in any direction.
