Stephanie Zimmermann

Stephanie Zimmermann (October 29, 1973-November 10, 2020) was a German physicist who worked on the ATLAS experiment at the Large Hadron Collider at CERN. As a researcher from the University of Freiburg, she was involved in the Muon Detector Control System activities, and she served as muon run-coordinator. She was elected and served as ATLAS Run-Coordinator in 2012–2014. She then became Project Leader of the New Small Wheel project (NSW), part of an extensive upgrade, the largest phase 1 upgrade project for the ATLAS detector. Education Zimmermann studied physics at the University of Freiburg, where she earned Master's and Ph.D. degrees, supervised by R.Schneider, Gregor Herten, and A.Bamberger. Career As a master's student in 1999, Zimmermann joined the ATLAS experiment, working on the muon system of the Large Hadron Collider at CERN. She continued her work in the ATLAS collaboration during her doctoral thesis, a research fellowship at CERN, and as a University of Freiburg researcher. Muon Run-Coordinator As research fellow she coordinated integration of the Monitored Drift Tube and Resistive Plate Chambers. This work ensured this task was completed on time for installation in the ATLAS underground hall. According to Andrew Millington she was "a leading member of the ATLAS muon group", with a major role in the Muon Detector Control System activities, and she served as muon run-coordinator.
