EIC MeetingJune JLab: Decadal Science Questions 4  What is the role of gluonic excitations in the spectroscopy of light mesons? Can these excitations elucidate the origin of quark confinement?  Where is the missing spin in the nucleon? Is there a significant contribution from valence quark orbital angular momentum?  Can we reveal a novel landscape of nucleon substructure through measurements of new multidimensional distribution functions?  What is the relation between short-range N-N correlations and the partonic structure of nuclei?  Can we discover evidence for physics beyond the standard model of particle physics? There would appear to be a good 10 year program of compelling science to be done

EIC MeetingJune At present, ATLAS/CARIBU at ANL Uniquely Provides SC funded Low Energy Research Opportunities Longer term, ATLAS niche is as a unique, complementary Stable Beam Facility for research on Nuclear Structure & Nuclear Astrophysics

EIC MeetingJune Facility for Rare Isotope Beams FRIB Linear Accelerator FRIB Site March 2014 FRIB will increase the number of isotopes with known properties from ~2,000 observed over the last century to ~5,000 and will provide world-leading capabilities for research on: Nuclear Structure  The ultimate limits of existence for nuclei  Nuclei which have neutron skins  The synthesis of super heavy elements Nuclear Astrophysics  The origin of the heavy elements and explosive nucleo-synthesis  Composition of neutron star crusts Fundamental Symmetries  Tests of fundamental symmetries, Atomic EDMs, Weak Charge This research will provide the basis for a model of nuclei and how they interact. The coils of this high temperature superconducting (HTS) quadrupole exceeded the required currents at elevated temperatures, indicating additional operating current margin and more stability.

EIC MeetingJune  FRIB physics is at the core of nuclear science: “To understand, predict, and use”  FRIB provides access to a vast unexplored terrain in the chart of nuclides FRIB: 21st Century Science Questions

EIC MeetingJune Main Remaining Questions What do we need to know about the initial state? Is it a weakly coupled color glass condensate? How does it thermalize? What do the data tell us about the initial conditions for the hydro- dynamic expansion? Can we determine it unambiguously? What is the smallest collision system that behaves collectively? What does the QCD phase diagram look like? Does it contain a critical point in the HG-QGP transition region? Does the HG-QGP transition become a first-order phase transition for large μ B ? What can jets and heavy flavors tell us about the structure of the strongly coupled QGP? What do the quarkonium (and other) data tell us about quark deconfinement and hadronization? Can we find unambiguous proof for chiral symmetry restoration?

EIC MeetingJune Preparations for NP Stewarded Neutrino-less Double Beta Decay Experiments Inspection of copper being electroformed at the Temporary Clean Room in SURF R&D on one of several approaches by U.S. scientists is ongoing at Lead, South Dakota Recent progress on the Majorana Demonstrator 4800 feet below ground at the Sanford Underground Research Facility (SURF) With techniques that use nuclear isotopes inside cryostats, often made of ultra-clean materials, scientists are “tooling up” to study whether neutrinos are their own anti- particle. NSAC has been charged to identify the criteria for a next generation double beta decay experiment.

EIC MeetingJune Neutrinoless Double Beta Decay NSAC Charge Scientific Importance Status of Ongoing and Planned Experiments

EIC MeetingJune Nuclear Theory The essential role of a strong nuclear theory effort goes without saying:  Poses scientific questions that lead to the construction of facilities  Helps make the case for, and guide the design of new facilities, their research programs and their strategic operations plan  Provides a framework for understanding measurements made at facilities  Topical Collaborations (fixed-term, multi-institution collaborations established to investigate a specific topic) appear to have been very successful and, resource permitting, the model will be continued Maintaining adequate support for a robust nuclear theory effort is essential to the productivity and vitality of nuclear science

EIC MeetingJune Nuclear Theory Computing Will Also Likely be a Discussion New GPU-based LQCD processor at TJNAF How many different nuclei exist? NP researchers theorize the number to be ~7,000

EIC MeetingJune Isotope Program Will Continue The mission of the DOE Isotope Program is threefold  Produce and/or distribute radioactive and stable isotopes that are in short supply, associated byproducts, surplus materials and related isotope services.  Maintain the infrastructure required to produce and supply isotope products and related services.  Conduct R&D on new and improved isotope production and processing techniques which can make available new isotopes for research and applications. Produce isotopes that are in short supply only – the Isotope Program does not compete with industry Produce isotopes that are in short supply only – the Isotope Program does not compete with industry

EIC MeetingJune Times Square NYC One Year Ago R&D Creates New Production Method for Actinium-225  A new isotope project at LANL shows promise for rapidly producing major quantities of a new cancer-treatment agent, actinium-225.  Using proton beams, LANL and BNL could match current annual worldwide production of the isotope in just a few days.  A collaboration among LANL, BNL, and ORNL is developing a plan for full-scale production and stable supply of Ac-225.  Ac-225 emits alpha radiation. Alpha particles are energetic enough to destroy cancer cells but are unlikely to move beyond a tightly controlled target region and destroy healthy cells. Alpha particles are stopped in their tracks by a layer of skin—or even an inch or two of air.

EIC MeetingJune Defining the Science – Long Range Plans The Long Range Plans have: Identified the scientific opportunities Recommended scientific priorities Effectively defining the field of Nuclear Physics for the Nation New LRP in Nation’s leadership role today is largely a result of: The responsible/visionary strategic planning embodied in the NSAC Long Range Plans Federal government’s decision to utilize the guidance and provide the needed resources 2007

EIC MeetingJune : A Long Range Plan for Nuclear Science First Mention of a Relativistic Heavy Ion Machine; Not Yet a Recommendation The major facility recommended by this plan turned out to be CEBAF

EIC MeetingJune Time from First Strong Recommendation to Operating Facility RHIC: 1983 to years CEBAF 12 GeV Upgrade 2002 to years ISOL Facility/RIA/FRIB 1996 to years CEBAF1979 to years There seems to be a constant of nature with respect to the timescale for realization of big initiatives EIC at the moment has no status with respect to nuclear science community priorities. The next LRP will be  2021 In addition to nuclear science priorities, there are other Office of Science priorities that will be in play From Recommendation to Realization Takes Time

EIC MeetingJune The Other Aspect: What else is potentially in the SC Queue? All kinds of things, always (ITER, LBNE, New Light Sources, New Leadership Computers, new Centers, new Hubs,... EIC will either be in the swim Or not

EIC MeetingJune To be in the swim at this point… A very strong science case with broad appeal need to be clearly articulated to and bought into by the nuclear science community (disclaimer, this is an observation, not an endorsement by the AD)

EIC: A color dipole microscope28 e−e− γ* Color dipoles “see” gluons Free color charges (e.g. quarks) do not exist, but color dipoles do! Virtual photons are an excellent source of color dipoles. Two resolution scales: momentum k (longitudinal) virtuality Q (transverse) ⇒ More powerful than an optical microscope! HERA was the 1 st generation color dipole microscope, with limited intensity and no polarization. EIC will be a 2 nd generation color dipole microscope, >100-fold intensity and polarization!

EIC MeetingJune The EIC: A QCD Laboratory 29 Gluon structure of the proton: How is the proton’s mass generated and what carries its spin? High density phase of cold gluon matter How do confined hadrons emerge from isolated quarks? Today’s EIC
