Professor Emeritus in Physics and the Enrico Fermi Institute
James Pilcher is a member of the ATLAS collaboration at CERN, the European laboratory for particle physics in Geneva, Switzerland. ATLAS (A Toroidal Large Hadron Collider Apparatus) has been helping physicists answer some of the most pressing questions in particle physics today since CERN's Large Hadron Collider (LHC) began operation in 2008. He is a member of the Chicago group that built the electronics for the LHC's calorimeter, which measures the energy produced in subatomic particle reactions. Previously, Pilcher had participated in the OPAL experiment at CERN, studying the properties of subatomics particle called the W and Z bosons. The OPAL experiment concluded in 2000.
