Introduction to the Working Groups: Preparing the Strategic Plan Robert V. F. Janssens Scientific Director of the ATLAS Facility Physics Division Director 2009 ATLAS Users Workshop, August 8-9, 2009.

Robert V.F. Janssens ATLAS User Workshop August 8-9, Strategic Plan: the 4 Science Goals (driven by the LRP) Understanding the stability and structure of nuclei as many-body systems built of protons and neutrons bound by the strong force. Exploring the origin of the chemical elements and their role in shaping the reactions that occur in the cataclysmic events of the cosmos. Understanding the dynamics governing interactions between nuclei at energies in the vicinity of the Coulomb barrier. Testing with high accuracy the fundamental symmetries of nature by taking advantage of nuclei with specific properties. Elements to optimize research output in the context of US efforts: - CARIBU and its unique beams and energy regime - ATLAS and its unique stable beam capabilities - new instrumentation (HELIOS, X-array, laser laboratory, gas filled spectr.,..) - upgrades of existing equipment (Gammasphere, FMA, CPT,..) At all times, remain flexible to adapt to new opportunities Nuclear Structure Milestones: NS3 ( Ni), NS6 (2013- micr. calc),NS7 (2013-GRETINA), NS8 (2015-Z>102), NS9(2018-changes in shell structure) Nuclear Astrophysics Milestones: NA4 (   C  ), NA6 (2012- r-process),NA9(2014-masses etc. for supernovae), NA10 (2014-reactions for X-ray bursts and novae) Nuclear Struct. & Astro. Milestones: NS3, NS8, NS9, NA4, NA6, NA9, NA10) Fundamental Int.. Milestones: FI4(2010-factor of 5 better contraint on SM), FI9(2013-EDM)

Robert V.F. Janssens ATLAS User Workshop August 8-9, An Updated Strategic Plan To help define the future (i.e. the strategic plan), the ATLAS Users Executive Committee & ATLAS management have come up with a set of questions: –What are the most important physics questions that you plan to study at ATLAS over the next five years? –How do these questions relate to the ATLAS Strategic Plan & the ATLAS efficiency and intensity upgrade plans? –How do these questions relate to the national priorities as expressed in the 2007 NSAC Long Range Plan and, the DOE-OMB performance measures? What other developments in accelerator capabilities and instrumentation do you envision as being needed to optimize your research program at the facility? Consider options included in the current plans and new possibilities. Did you identify other important issues that the Executive Committee of the ATLAS User Group and the ATLAS management should make a priority for the facility?
