Dr Peter Jenni, CERN, Switzerland
Peter Jenni, Swiss, born in 1948, obtained his Diploma for Physics at the University of Berne in 1973 and his Doctorate at the Swiss Federal Institute of Technology in Zürich (ETHZ) in 1976. Peter Jenni participated in CERN experiments at the Synchro-Cyclotron (SC, 1972/3), at the Proton Synchrotron (PS, 1974/6), and as ETHZ Research Associate at the Intersecting Storage Rings (ISR, 1976/7). During 1978/9, he was a Research Associate at the Stanford Linear Accelerator Centre (SLAC), USA, participating in the MARK II experiment at the e+e– storage ring SPEAR. He became a CERN staff in 1980 with the UA2 experiment at the SPS collider (major involvement in the discoveries of jets and the W/Z bosons). His strong interest was with the Large Hadron Collider (LHC) since the beginning in 1984. From 1991 the main activities concentrated on tasks related to the spokespersonship first of a proto-Collaboration (Expression of Interest, 1992), and then, on the shared spokespersonship with F. Dydak of the ATLAS Collaboration (Letter of Intent 1992, Technical Proposal 1994). In October 1995 he was elected Spokesperson of ATLAS which today comprises some 3000 scientists representing 174 Institutions from 38 countries. He was re-elected several times and retired from this duty in February 2009, retaining a strong involvement in the operation and physics of the experiment.
