Two University of Iowa teams are designing and testing a new generation of subdetectors as the Large Hadron Collider (LHC) goes under the knife for an upgrade. The teams are led by Professor Usha Mallik, Professor Yasar Onel and Associate Professor Jane Nachtman in the UI Department of Physics and Astronomy, reports the University of Iowa. Mallik’s team works with ATLAS, a particle detector at the LHC, to lead computer simulations that model how the new subdetector will operate. Onel and Nachtman’s team, meanwhile, work with the Compact Muon Solenoid (CMS) to design sensors that track the paths of individual particles created by proton collisions at the LHC.
