Peter Jenni, (born 17 April 1948) is an experimental particle physicist working at CERN.[1] He is best known as one of the "founding fathers" of the ATLAS experiment at the CERN Large Hadron Collider together with a few other colleagues. He acted as spokesperson (project leader) of the ATLAS Collaboration until 2009.[2] ATLAS is a world-wide collaboration which started in 1992 [3] involving roughly 3,000 physicists at 177 institutions in 38 countries.[4] Jenni was directly involved in the experimental work leading to the discoveries of the W and Z bosons in the 1980s and the Higgs boson in 2012.[5][6] He is (co-)author of about 450 publications in scientific journals.
Early life and education
[edit]Peter Jenni, Swiss, born in 1948, obtained his Diploma for Physics at the University of Bern in 1973 and his Doctorate at the Swiss Federal Institute of Technology in Zürich (ETHZ) in 1976. His thesis examined very small angle elastic scattering in the Coulomb-nuclear interference region. Peter Jenni is married and has two children.
Research career
[edit]Peter Jenni participated in CERN experiments at the Synchro-Cyclotron (1972/3), at the Proton Synchrotron (1974/6), and as ETHZ Research Associate at the Intersecting Storage Rings (ISR) (1976/7), the first high-energy hadron collider. From 1974 to summer 1976 he worked as a CERN Fellow in the group of M. Ferro-Luzzi. The group measured the Coulomb-nuclear interference scattering of
From 1976 to 1977 Research Associate at the Swiss Federal Institute of Technology in Zürich (ETHZ) working in the CERN-ETH-Saclay collaboration R702 at the CERN Intersecting Storage Rings (P. Darriulat, B. Richter). The experiment covered studies on electron pair production, on e
During 1978 and 1979, Research Associate at the Stanford Linear Accelerator Centre (SLAC), Stanford, USA, in B. Richter's group. Participated in the MARK II SLAC-LBL Berkeley experiment at the e+e– storage ring SPEAR. Mainly involved in the following physics analyses: two-photon reactions, meson form factors, and search for the charmed mesons.
The first measurement of the two-photon widths of the
He became a CERN staff member in 1980 working with the UA2 experiment at the Super Proton Synchrotron collider (major involvement in the discoveries of jets and the W and Z bosons). Worked on the design for the UA2 upgrade since 1984, with special motivation for missing transverse energy signatures. Project leader of the new end cap calorimeter constructed for the upgraded UA2 experiment. As from March 1987, also group leader of the CERN UA2 group. Coordinated calorimeter and trigger work for the upgraded UA2 experiment.
Already during the UA2 time, strong interest in the physics and instrumentation at future colliders, in particular LHC. Early involvement as convener of the jet study group at the ECFA-CERN LHC workshop 1984 (Lausanne, Geneva), member of the advisory panel on the physics potential and the feasibility of experiments at the multi-TeV energies (La Thuile workshop 1987), and calorimetry overview at the ECFA study week on instrumentation technology for high-luminosity hadron colliders (Barcelona 1989).
He more and more shifted[7] to the Large Hadron Collider (LHC). From 1991 the main activities concentrated on tasks related to the informal spokespersonship first of a proto-Collaboration. Peter Jenni was involved in the early phases of the calorimeter R&D projects RD1 and RD3, during 1990–1992. In 1995, after formal approval of the ATLAS project, he was elected Spokesperson of the experiment, which today comprises some 3000 scientists representing 177 Institutions from 38 countries. He was re-elected several times and retired from this duty in February 2009, retaining however a strong involvement in the operation and physics of the experiment.[8]
After his retirement as a CERN Senior Research Staff end of April 2013, Peter Jenni has become a Guest Scientist with the Albert-Ludwigs-Universität Freiburg, keeping his full engagement with the ATLAS experiment.
Advisory roles - Major physics committee involvement
[edit]- Final two years of the ISRC, CERN (1982 and 1983)
- Four years LEPC, CERN (1986 – 1990)
- Almost five years PRC of DESY as referee on the HERA experiment calorimetry, DESY, Hamburg, Germany (1984 – 1989)
- First few years of SSC PAC, Dallas, U.S. (1989 – 1991)
- Joint Institute for Nuclear Research(JINR) Dubna Scientific Council (since 2008)
- Over the last 18 months he was strongly involved in shaping the scientific input with the Preparatory Group for the Update of the European Strategy for Particle Physics, personally motivated to promote CERN’s future at the high energy frontier.
Invited lectures and outreach
[edit]Peter Jenni is frequently invited to give public lectures on experimental particle physics at the LHC. Jenni is well known for his efforts to involve also physicists from countries that are not CERN member states in the construction of the ATLAS experiment. As a Spokesperson he frequently interacted with scientists from all five continents as well as with many funding agencies and science authorities. Thanks to his efforts many universities and institutes from a wide variety of countries became members of the ATLAS Collaboration making it a truly international experiment. He often says that the biggest reward for him is to see how enthusiastic and motivated young people are about physics and he constantly tries to help future generations to get the same or even more opportunities in high energy physics.[9]
