Description

Gigi Rolandi is a member of the Compact Muon Solenoid (CMS) Collaboration and a Senior Research Physicist at the European Laboratory for Particle Physics (CERN), where he has conducted research since 1975. Since 2008 he is teaches Experimental high Energy Physics at Scuola Normale Supriore in Pisa. Dr. Rolandi studied physics and experimental high energy physics at the exclusive Scuola Normale Superiore in Pisa, Italy. Under his thesis advisor, Lorenzo Foà, he participated in the R&D, construction and commissioning of the drift chambers and the Cherenkov detectors of the NA1 experiment, installed in the H4 beam line of the CERN SPS, and later in the analyses for the determination of charmed hadrons lifetimes, using for the first time an active silicon target. At the age of 25, Dr. Rolandi was offered an assistant professorship at the University of Trieste and started a new HEP group that participated in the NA1 and NA7 Collaborations. In the NA7 experiment, he contributed to the design and analysis of the measurement of the pion electromagnetic form-factor at threshold in the time-like region. This experiment was based on producing pion pairs with a positron beam on a hydrogen target; it is, to date, the most precise measurement of the pion form factor in that energy range. In the early 80’s CERN was expected to build an electron–positron collider energetic enough to produce the as yet undiscovered Z boson. Dr. Rolandi contributed to the international effort to design a sophisticated and effective apparatus (ALEPH) for the precision study of the properties of the electroweak interaction. The ALEPH Collaboration had chosen, for the central tracker, the new TPC technology, even though the only previous attempt – the PEP4 TPC – was experiencing great difficulties because of drift distortions. Gigi Rolandi, together with Francesco Ragusa, studied the resolution error associated with the drift of the ionization electrons in the electric and magnetic fields, as well as the error associated with the production of the signals on the pads of the wire-chamber planes. The most significant result of this study was the understanding of the importance of the magnetic field as stabilizer of the ionization electrons’ drift paths. This and other studies on the ALEPH TPC are collected in Particle Detection with Drift Chambers, written by Gigi Rolandi together with Walter Blum, a book which became a reference for builders of gas-based particle detectors. In 1989, with the LEP start-up drawing near, Gigi Rolandi was asked by Jack Steinberger, ALEPH spokesperson and founder, to steer and stimulate the evolution of the Collaboration from a “subdetectors’ community” to a running experiment. The traditional “Gigi” Tuesday meetings that he started in 1989 and chaired for five years marked the ALEPH Collaboration: they were the forum where the readiness and the experimental programme and later all conference contributions and papers, were discussed and approved. Precision electroweak physics was the most intense physics topic in the early 90’s. Dr. Rolandi made central contributions to the ALEPH analyses on the measurements of the Z boson properties and the determination of the number of neutrino families. From 1992 to 1994 Rolandi chaired the LEP Energy Calibration Working Group, which provided the first precise energy calibration of LEP, allowing a measurement of the Z boson mass with a precision of 1.4 MeV. February 2008 In 1994 Dr. Rolandi was elected spokesperson of the ALEPH Collaboration. In this role, he managed the transition to the high-energy period of LEP, starting with 130 and 136 GeV runs in November 1995. ALEPH was a very successful experiment, which produced more than 250 high-quality papers. Dr. Rolandi made major contributions to this scientific production directly and in his capacity as a member of the ALEPH editorial board, from 1991 to the present, and as its chairperson from 1997 to 2000. In 1997 – at the end of his term as ALEPH spokesperson – Rolandi declined the offer to stand for a second term and joined the CMS Collaboration, which was constructing a large and challenging detector for experimentation at the new high-energy frontier: the CERN Large Hadron Collider. In 1998 Dr. Rolandi joined the CMS Tracker Project. He reorganized its managerial structure by introducing the Tracker Steering Committee as the top decision-making body. In 1999 he played a major role in the decision to change the baseline design into an “all-silicon” tracker. In 2000 Rolandi became Project Manager and restructured the CMS Tracker project in order to face the task of building a detector with an unprecedented number of silicon sensors in five years. In the following years, the facilities for building and testing 16,000 silicon modules were put in place at more than 20 sites world-wide. Since 2005 Dr. Rolandi has engaged in the preparation of Physics analyses in CMS. He designed the approval process for physics analyses that was subsequently adopted by the Collaboration. He designed the management tools to steer the many analyses that are active in CMS at the same time and the Collaboration Wide Review of CMS papers. Since 2006 he is the Chair of the CMS Publication Committee and chairs many of the Analyses Review Committee. As CMS Editor he is responsible for the publication of all scientific notes and papers of the Collaboration. Dr. Rolandi is member of the Editorial Board of two of the most prestigious journals of HEP: Physics Letters B and The Journal of High Energy Physics. Dr. Rolandi served as member of numerous HEP Committees including LEPC at CERN, EPAC at SLAC, LHCC at CERN, PPESP in the UK, and RECFA. From 2001 to 2004, Dr. Rolandi was the chairperson of the DESY Physics Research Committee. Since 2007 Dr. Rolandi teaches Experimental Particle Physics at Scuola Normale Superiore in Pisa. Dr. Rolandi is author of some 300 publications on refereed journals; a selected list is available at http://cern.ch/rolandi/publications.html
