Fermi National Accelerator Laboratory
"The silicon microstrip vertex detector for experiment #E691 at Fermilab is used to measure charmed particle decays to an accuracy of less than one thousandth of an inch. The silver cables carry signals from 7000 detector elements built on silicon chips similar to those used for micro-electronic circuits. The experimentor is adjusting the beryllium target which is struck by a photon beam to produce the particles. The experiment is a joint collaboration of physicists from Brazil, Canada and the United States."
