CDF Collaboration
The first physics results were obtained during 1987, in an engineering run, and in 1988/89, in a year-long run. Upgrades for the 1991 run are described in the FNAL-775 proposal, and another major improvement was proposed for the 1993 run. CDF is a general-purpose detector designed to study the physics of p pbar collisions. It has both azimuthal and forward-backward symmetry. A superconducting solenoid of length 4.8 m and radius 1.5 m generates a 1.4 T magnetic field and contains tracking chambers used to detect charged particles and measure their momenta. Surrounding the solenoid are sampling calorimeters used to measure the electromagnetic and hadronic energy of jets and electrons. Outside the calorimeters are drift chambers used for muon detection. Surrounding the beam pipe is a 4-layer silicon microstrip vertex detector, and a vertex drift chamber, both installed in 1992. The Collider run ended in Spring 96 with a total luminosity of 110 pb**(-1) recorded on tape. The detector will be upgraded with new tracking, vertex detector, scintillating tile plug calorimeter, readout and trigger electronics, and extended muon coverage for the next Collider run with the Main Injector, now scheduled for April, 1999. Upgrade is complete ans data taking has resumed (March 2001).
