• About

  Professor Campbell is currently working at the Collider Detector Facility at Fermilab (CDF). This large general purpose detector is used to study the nature of proton-antiproton collisions at an energy of 1.8 Teraelectronvolts. The collisions between protons and antiprotons actually occur between the partons (quarks and gluons) in the protons, with each parton carrying a fraction of the proton's momentum. Thus, a wide spectrum of known particles is made with masses all the way up to Mtop=176 GeV, and the experiment is sensitive to new particles with masses up to 400 GeV. The Michigan group currently studies the systematics of top quark production and decay. There are about five million interactions per second in the detector, with each interaction producing about 250 kilobytes of data. A collection of custom electronic devices examines this data in real time and determines which events should be kept for further study. University of Michigan physicists design and build the electronics for this trigger, and therefore have a large impact on the whole experiment.

  Professor Campbell is a Fellow of the American Physics Society.
