Research Biography Ian Shipsey

Ian Shipsey joined CMS in 2001. As a Level-4 CMS Forward Pixel manager he coordinated the development of the assembly and verification techniques and then the production and testing of all of the forward silicon sensor pixel detector modules (plaquettes) for CMS at Purdue by 14 undergraduate and graduate students. In 2010 he served as the Quarkonia Working Group co-Convener with Fabrizio Palla (Pisa). The QWG produced the first measurement of the Upsilon production cross section at the LHC and, as a byproduct, an eye-catching plot that simultaneously shows many standard model particles, from the eta to the Z, a spectroscopist’s delight! In 2011 the team, with Heavy Ion colleagues, found an indication of sequential Upsilon suppression in heavy ion collisions, regarded by many as a smoking gun for

the Quark Gluon Plasma. The paper was Editor’s Choice in PRL in July last year. Updates to both the pp Upsilon cross section and Upsilon production in heavy ion collisions are currently proceeding through the approval process. Recently the group has joined the RAL-Princeton team to search for new physics through the detection of displaced vertices. In 2008 Ian became chair of the Advisory Board to the LHC Physics Center (LPC) at Fermilab. The LPC is a regional CMS center that facilitates participation in CMS for those that cannot travel to CERN. In late 2009 Ian became the co-coordinator the LPC for a two-year term, and was subsequently reappointed in September 2011. In 2009 he co-developed and led a successful hands-on CMS data analysis school for sixty students taught by sixty facilitators, which has since been repeated annually at the LPC, and in 2012 for the first time in Pisa. Ian co-developed the CMS Fellows program. In the past year he has chaired the CMS ARCs for the observation of left-hand polarized W production at the LHC, and Higgs searches to the four lepton final state, and the two leptons and two tau decays final state. He is a member of the CB Advisory Group.

Ian received a B.Sc. from Queen Mary, London in 1982 and a Ph.D. from the University of Edinburgh in 1986 for studies of CP violation in the kaon system with the NA31 experiment at CERN. He was a post doc and then research professor at Syracuse University before joining Purdue University in 1989 as an assistant professor. He is currently Julian Schwinger Distinguished Professor of Physics at Purdue. He joined the CLEO experiment in 1986. He helped to design and lead the fabrication of the CLEO II muon detection system, searched for rare B-meson decays and made precision measurements of Vcb and Vub. After joining Purdue he received a NSF National Young Investigator Award (one of two in elementary particle physics in the U.S. in 1992) that provided the funding to establish a MicroStrip Gas Chamber (MSGC) lab. To his surprise, Ian became the first person in the U.S. to successfully design and build by hand a working MSGC. This included mask manufacture using e-beam lithography, and all steps in the subsequent U.V. lithographic process, including vacuum vapor deposition of the metal film and spin-on and development of the photo resists. He joined the SDC Collaboration to apply the MSGC technology to forward tracking. In 1993 he received an SSC National Fellowship (one of 12 awarded annually). Shortly before the SSC was terminated he was part of the team that made the decision to abandon MSGC technology in favor of silicon microstrip detectors. Ian subsequently continued a modest program in Micro Pattern Gas Detectors building the first 2-D readout ion-implanted kapton MSGC, and with Juan Collar of Chicago and 3M Corporation the first mass-produced GEM and with 3M the first mass-produced MicroMEGAS. In 1995 he co-founded with Daniela Bortoletto, the 300 m2 class 100,000 Purdue Particle Physics Microstructure Detector Laboratories (P3MD), which have been described by reviewers as a national treasure. From 1994-2000 Ian lead the assembly team for the CLEO III silicon vertex detector. The detector was assembled in P3MD with the help of 17 undergraduates. In a dedicated CESR run Ian and his students made the first observation of the production of the strange B meson at the Y(5S), this is important input to the B physics program of super B factories, and he conducted a comprehensive study of charm baryon semileptonic decays reported in a sequence of five papers. In 2000 Ian was one of the intellectual leaders of a group who proposed and designed a new experiment, CLEO-c, to test Lattice Gauge Theory calculations and search for new physics in the charm sector. He played the leading role in generating community support for the CLEO-c proposal. The project was approved by the U.S. NSF and U.S. DOE. in 2002. Ian recruited new university groups to the project and established the CLEO-c Collaboration. He served as the elected co-Spokesperson of CLEO III and then CLEO-c for three consecutive terms between 2001 and 2004. He became an APS Fellow in 2002 for contributions to heavy quark flavor physics. CLEO-c took data until 2008 opening a new frontier in our understanding of the weak and strong interactions. Precision measurements have provided critical tests of Lattice QCD and validated the approach at the several percent level. Ian, with his students and post docs and together with the Cornell group of Ritchie Patterson and Lawrence Gibbons performed the CLEO-c flagship charm semileptonic decay analyses including the first observation of five new charm semileptonic decays

and the most precise and robust measurements of the semileptonic form factors in D→K/πeν providing a crisp test of LQCD. They extracted the CKM matrix elements Vcs and Vcd with an experimental precision of 1% and 3% respectively- the most precise and most robust determinations of these quantities at that time. The results were published in the 500th paper submitted to a peer-reviewed journal by CLEO in 2009. The group with Cornell (Anders Ryd and David Cassel) and Carnegie Mellon also studied D meson hadronic decays and made several contributions to charm spectroscopy including discovery of 13 new decay modes of the psi(2S). Over 100 CLEO-c papers have been published and dozens of theses written. The CLEO-c goal has been met: the worldwide heavy quark physics program is more sensitive today to new physical phenomena than at any previous time. If the LHC discovers new physics, it is possible that the ability to sort between new physics scenarios will require studying the effect of the new physics on the beauty quark and charm quark systems. Ian’s last CLEO paper is currently being reviewed by PRL. With Ian’s ninth Purdue CLEO Ph.D. student graduating the group’s CLEO work has concluded. Ian is a member of the Large Synoptic Survey camera team and serves on the Board of Directors of LSST. At the heart of LSST is a 3 Giga pixel CCD digital camera the largest ever constructed for astronomy. Obtaining images of sufficient quality to study dark energy using gravitational weak-lensing requires that the alignment and focus system of the camera performs extremely well. Driven by a long-standing interest in cosmology and building on experience gained with previous instrumentation projects, in 2008 Ian established a new laboratory to evaluate CCDs. The Purdue team will build, in collaboration with BNL, Harvard, IN2P3 and SLAC, a part of the LSST camera that will determine if the telescope and camera is pointing at the correct place in the sky (guiding) and in focus (wave-front sensing). This is crucial to achieve the dark energy science goals of the project. In 2009 Ian was appointed to the LSST Board of Directors and in 2010 with a post doc he made the first simulation of LSST using the Open Science Grid. He is currently collaborating on the photon end-to-end simulation of the measurement of dark energy using weak-lensing, and laboratory tests and simulation of wave-front sensing and guiding at Purdue. In July 2011 he co-organized the internal LSST readiness review that identified a number of significant vulnerabilities in the project that were subsequently corrected. The review is widely credited with having been crucial for the subsequent successful NSF Preliminary Design Review in August 2011. The success of Ian’s group is measured as follows: undergraduates that work with him go on to top graduate schools: Chicago, Cornell, Penn, Stanford, MIT, and UIUC, and the graduates and post docs go on to permanent positions in academia and industry: Professors at Nanjing and USTC, tenured Scientists at FNAL, BNL and Pacific North West Laboratories, and one ex-member is president of a Silicon Valley company. Service on national committees is critical to assessing the health, and setting the direction, of the field. Ian has had the privilege to serve on numerous national committees, including the SLAC Policy Committee (Stanford U.), FNAL Program Advisory Committee, the Particle Astrophysics Scientific Assessment Group (DOE & NSF), the American Physical Society Panofsky Prize (Chair), Division of Particle Fields Task Force on Instrumentation (Chair), BNL/JLAB Electron Ion Collider Instrumentation Panel (Chair), Physical Sciences Directorate at ANL U. Chicago Review Committee, and the High Energy Physics Advisory Panel to DOE and NSF. Ian was elected vice-Chair/Chair-elect/Chair/past-Chair of the Division of Particles and Fields of the American Physical Society (2012-2015). Likewise, service on departmental, college and university committees is a vital part of faculty life. It was an honor to be elected by physics colleagues at Purdue to chair the committee charged with identifying a new Head for the physics department in 2007 in an international search. Ian loves to teach and has received teaching prizes both from the students and the faculty at the departmental, college and university levels including being inducted into the Purdue “Book of Great Teachers.” Approximately 250 faculty have received this honor in the 140 year history of Purdue. He also greatly enjoys, and has been extensively involved in outreach. The opportunity to describe the LHC program at “Big Bang 2.0” to 400 members of the public at the Carnegie Institution in Washington D.C. sponsored by the Swiss Embassy is a recent highlight. Instrumentation is the great enabler of our science it has also enabled Ian to hear. He has had the opportunity to give over sixty colloquia and talks to community groups on hearing, cochlear implants and perception since 2003. If elected CB Chair, Ian will move to CERN. He will step down as an LPC coordinator and from the Board of LSST. LSST camera production is not expected to start until 2015. If it starts earlier Purdue Professor Wei Cui will substitute for Ian. Ian will be chair-Elect of the Division of Particles and Fields of the APS in 2013 and Chair in 2014. It is estimated that this will require a 15% time commitment and six trips to the U.S. A CV is available here: http://dl.dropbox.com/u/24655052/shipsey-CV-general-short-2011-for-DoE-NSF-Nov-2011-v2.pdf
