You must dare to think differently, see things from different sides, in order to come across fortuitous new ideas frequently. You should develop even the most stupid ideas and when you do this systematically, there will always come something useful out of it. — Simon van der Meer (1925–2011) Nikhef 0 FOM-11.0937 Strategic Plan 2011-2016 FOM Institute forfor SubatomicS Physics Nikhef Colophon Publication edited for Nikhef Nationaal instituut voor subatomaire fysica National Institute for Subatomic Physics Address: Postbus 41882, 1009 DB Amsterdam Science Park 105, 1098 XG Amsterdam Telephone: +31 20 592 5001 Fax: +31 20 592 5155 E–mail: [email protected] URL: http://www.nikhef.nl Editors: Patrick Decowski, Kees Huyser, Frank Linde, Vanessa Mexner, Arjen van Rijn, Leo Wiggers Layout/art-work: Kees Huyser, Drukkerij Badoux - Houten Photos: Kees Huyser, Jan Koopstra, Marco Kraan, Charles Timmermans, ARCADIS Nederland BV, CERN, Erasmus MC, Nikhef Cover: Kees Huyser This document is produced for the NWO evaluation of the FOM Institute for Subatomic Physics. It describes the strategy for the period 2011–2016 and beyond. Nikhef is the National Institute for Subatomic Physics in the Netherlands, in which the Foundation for Fundamental Research on Matter, the University of Amsterdam, VU University Amsterdam, Radboud University Nijmegen and Utrecht University collaborate. Nikhef coordinates and supports the activities in experimental particle and astroparticle physics in the Netherlands. The Foundation for Fundamental Research on Matter (FOM) is part of the Netherlands Organisation for Scientifi c Research (NWO). Nikhef participates in experiments at the Large Hadron Collider at CERN, notably ATLAS, LHCb and ALICE. Astroparticle physics activities at Nikhef are fourfold: the ANTARES and KM3NeT neutrino telescope projects in the Mediterranean Sea; the Pierre Auger Observatory for cosmic rays, located in Argentina; gravitational-wave detection via the Virgo interferometer in Italy, and the projects LISA and Einstein Telescope; and the direct search for Dark Matter with the XENON detector in the Gran Sasso underground laboratory in Italy. Detector R&D, design and construction take place at the laboratory located at Science Park Amsterdam as well as at the participating universities. Data analysis makes extensive use of large-scale computing at the Tier-1 facility operated by the Grid group. Nikhef has a theory group with both its own research programme and close contacts with the experimental groups. 2 Nikhef Strategic Plan 2011-2016 Contents Preface . 4 1 Introduction . 7 1.1 Introduction . 8 2 Physics Programmes . 17 2.1 Accelerator-based particle physics . 19 2.1.1 Physics at the TeV scale: ATLAS . 23 2.1.2 Physics with b-quarks: LHCb . 27 2.1.3 Relativistic heavy-ion physics: ALICE . 31 2.2 Astroparticle physics . 34 2.2.1 Neutrino telescopes: ANTARES and KM3NeT . 36 2.2.2 Gravitational physics: Virgo, LISA & ET – the dynamics of spacetime . 39 2.2.3 Ultra high-energy cosmic rays: Pierre Auger Observatory . 42 2.2.4 Dark matter: XENON . 45 2.3 Enabling physics programmes . 48 2.3.1 Theoretical physics . 49 2.3.2 Detector R&D . 52 2.3.3 Physics data processing: Grid computing . 56 3 Technical Skills and Infrastructure . 59 3.1 Introduction . 60 3.2 Facilities . 61 3.3 Technical departments . 63 4 Outreach, Education and Knowledge Transfer . 67 4.1 Outreach and education . 68 4.2 Knowledge transfer . 72 5 Finances 2011–2016 and beyond . 75 5.1 Finances 2011–2016 and beyond . 76 5.2 Mission budget increase . 80 Appendices . 81 A SWOT analysis . 82 B National & international context . 84 C Organigram . 87 D Glossary . 88 3 Strategic Plan 2011-2016 Nikhef Preface Scientifi cally, the time frame covered by Nikhef’s “Strategic Plan 2011–2016” promises to become the most exciting period in the history of Nikhef. Foremost, because of CERN’s Large Hadron Collider (LHC) program which, after a false start in 2008, made a superb comeback in 2010: a 100,000-fold increase in the peak luminosity and essentially a S rediscovery of half a century of elementary particle physics (K 0, J/ψ, W, Z and top). Unless Nature is completely uncooperative, the ATLAS and LHCb experiments will –with the data of the 2011–2012 proton-proton LHC run– fi nally shed light on two long-standing dilemmas in elementary particle physics: • Does the Standard Model Higgs particle exist? • Do we live in a supersymmetric world? When the Higgs particle will indeed be found, this will be the fi rst step towards a better understanding of the masses of the elemen- tary particles. If supersymmetry is discovered, this will unveil an entirely new direction in elementary particle physics research, in- cluding new particles explaining the mysterious dark matter in the Universe. Moreover, if Nature is really kind, even completely unex- pected new phenomena could be discovered at the LHC. Finally, with the LHC in heavy-ion, lead-lead, instead of proton-proton mode, the ALICE experiment will study the quark-gluon plasma, a state of matter common in the very early stage of the Universe. Secondly, because Nikhef’s four astroparticle physics endeavours Discussion on long-term strategy at the annual meeting 2006, are also entering an extremely exciting era. Front-line research well before the start of LHC. questions in this emerging interdisciplinary fi eld: • Do gravitational waves exist? • What is the nature of dark matter? • Do high-energy neutrino point sources exist? • What is the origin of high-energy cosmic rays?
