Perspectives from DOE Nuclear Physics RHIC User Meeting June 27, 2013
FY 2014 Nuclear Physics Budget Highlights Discovering, exploring, and understanding all forms of nuclear matter • Construction continues on the 12 GeV CEBAF Upgrade to provide world-leading capability for research on the quark structure of nucleons and nuclei; beam development and commissioning activities are initiated. • Construction is supported for FRIB to provide world-leading capability and new discovery potential for U.S. leadership in nuclear structure and nuclear astrophysics. • RHIC operations capitalize on a 10-fold enhancement in luminosity to discover the properties of the new Perfect Quark-Gluon Liquid state of matter and other emergent phenomena in relativistic heavy ion collisions. • ATLAS provides new beams for research on the origin of the elements in the cosmos with the newly operational Californium Rare Isotope Breeder (CARIBU) upgrade. • Forefront research, development, and production of stable and radioactive isotopes is provided for science, medicine, industry, and national security.
Office of Science FY 2014 Budget Request to Congress 1/ Annualized CR per FY 2014 President’s Budget (= FY 2012 + 0.612%) RHIC User Meeting, June 27, 2013
Nuclear PhysicsFY 2014 President’s Request by Subprogram 1/ Includes $12,745k for SBIR/STTR for comparability with FY 2013 and FY 2014 2/ Details will be submitted in an operating plan to Congress at the end of April. • Significant Changes • Medium Energy increase reflects critical transition of staff from the 12 GeV project back to operations as construction ramps down and project funding decreases • Low Energy increase reflects ramp up of FRIB construction (+$33M) RHIC User Meeting, June 27, 2013
Impacts of FY 2013 CR and Sequester • NP operated conservatively under the first CR that ran through March 27. • Annual funding levels were planned at the FY 2013 President’s Request level, not the FY 2012 appropriation level. • The net sequester cut from the FY 2013 operating level, therefore, is only $7M, not the $27M reduction relative to FY 2012. • To the extent possible, NP has worked to create flexibility to try to mitigate impacts and support the most critical mission activities • Per the enacted full-year CR, DOE has an obligation and spending plan • This plan provides the details of how the sequester will be distributed. • A reprogramming request to move the excess funds provided to the 12 GeV CEBAF Upgrade project to the rest of the NP program to partially mitigate impacts was approved by Congress. • Worst impacts such as furloughs will be avoided—this fiscal year; Other impacts to facility operations such as delayed and deferred capital and accelerator equipment purchases and projects, and impacts to some NP programs will occur.

Recent NP AccomplishmentsSolved: The Case of the Missing “Excited” Nucleons The Science Scientists conducting experiments at the Thomas Jefferson National Accelerator Facility (TJNAF) discovered some key, heavier mass (“excited”) versions of the nucleon (i.e. neutron and proton) called “N*s” (pronounced N-stars). These N*s were previously thought to be “missing” – predicted but not in existence. Interior view of the CEBAF Large Acceptance Spectrometer (CLAS) at TJNAF The Impact Recently, our most sophisticated Lattice-QCD calculations have confirmed long-standing Quark model predictions for a large number of excited nucleon levels that as yet have not been identified. The complete absence of such “missing” states would seriously question our understanding of the nucleon. Summary This discovery addresses a key question: how do the fundamental constituent particles of the Standard Model (quarks, antiquarks and gluons) assemble to form the composite “strongly interacting” particles observed in nature We now know the proton is best described by the dynamics of 3 quarks. The new particles discovered by CLAS have now been included in the Particle Data Group’s 2012 Review of Particle Properties. RHIC User Meeting, June 27, 2013
JLab: 21st Century Science Questions • 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? The Office of Science is in the final phase of a major upgrade of the CEBAF Accelerator at TJNAF to provide forefront capability to address this science RHIC User Meeting, June 27, 2013
Facility for Rare Isotope Beams FRIB Site February 2013 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.

RHIC Science is at its “High Tc Superconductivity” Moment RHIC has discovered a completely new state of matter (a perfect quark-gluon liquid) which is just as momentous and exciting as the discovery of high temperature superconductivity in condensed matter physics • There is a rich program of science ongoing and planned in the next 3 -5 years to: • determine, with precision, the detailed properties of this new matter • further explore and develop intellectual connections and broader impacts in other subfields of new insights and knowledge gained • search for new discoveries such as the postulated Critical Point in the phase diagram of QCD • explore the gluon and sea quark contributions to the spin of the proton using the only collider with polarized beams RHIC User Meeting, June 27, 2013
Productivity & Impact of the RHIC Program More than 40% of all-time top-cited Nuclear Theory arXiv papers are RHIC-related About 30-40% of nuclear physics PHD’s produced annually come from RHIC >190 tenured faculty positions associated with RHIC No rate falloff in citations (use) of RHIC research RHIC User Meeting, June 27, 2013
Recent RHIC Result Putting a New Spin on the Proton The double spin asymmetry shown is studied for inclusive jet production in polarized proton collisions at RHIC to assess the contribution of to the proton spin from gluons. The dashed blue curve is predicted if the gluon contribution (helicity preference) is zero. • The latest RHIC p+p spin results indicate clear helicity preferences among gluons carrying ~5-20% of proton momentum, corresponding to a contribution from these gluons of ~ 20% to the overall proton spin • The conclusion to a decade -old question is that gluons contribute to proton spin comparably to quarks! • Further measurements @ s = 500 GeV and for di-jets will extend momentum fraction (Bjorken x) range downward and provide addition information on the x-dependence of this contribution RHIC User Meeting, June 27, 2013
New Tools to Study the Perfect Quark Gluon Liquid The Heavy Flavor Tracker for the STAR Experiment at RHIC Barrel and Forward Vertex Detector for the PHENIX Experiment at RHIC Instrument investments of $29M over the last 3-4 years have or will begin data collection by FY2014. An additional investment of $30M in modest machine upgrades over the same period has increased the heavy ion luminosity at RHIC by more than a factor of ten. RHIC User Meeting, June 27, 2013
Preparations for Neutrino-less Double Beta Decay Exps. Using 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. The answer could help determine why the matter/anti-matter ratio today is far different than in the early cosmos. R&D on one of several approaches by U.S. scientists is ongoing at Lead, South Dakota • 4800 feet below ground, the copper needed for a cryostat to cool sensitive Germanium detectors is being electroformed to avoid induced backgrounds caused by cosmic rays The cyrostat, made from some of the purest copper in the world, is also prepared 4800 ft underground RHIC User Meeting, June 27, 2013
Isotopes and Radioisotopes in Short Supply Provided at Full Cost Recovery Some key isotopes and radioisotopes and the companies that use them Bracco Diagnostics Inc. Spectrum Techniques RHIC User Meeting, June 27, 2013
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. Times Square NYC RHIC User Meeting, June 27, 2013

Additional NP News and Events • A RHIC Operations Review by the Office of Project Assessment is presently scheduled for August 6-8, 2013. • A review of the 12 GeV Upgrade to address primarily the impacts of the directed funding change in FY 2012 ($50M vs $66M in the project baseline) occurred May 7-9, 2013. Rebaseline expected in September • One-day site visit for TJNAF (July 9) and S&T review for ATLAS (July 30-31) planned in FY2013. • A Lehman review to establish CD2/3a for FRIB was held June 4-5, 2013. SC/NP, in discussion with the FRIB project team, is examining options to continue progress under the full year 2013 Continuing Resolution. • ECA process completed for FY2013; gearing up for FY2014. • NSAC COV report (J. Harris, Chair) was been received; NP’s response has been posted • NSAC’s response to theSC Director’s Facilities Charge has been submitted to SC • DOE is developing a plan in response to the OSTP memo on Open Access RHIC User Meeting, June 27, 2013
Additional NP News and Events Within NP, and in preliminary discussion with HEP, there has begun to be some rumination about how to carry out a possible down-select process if the science “demands” that a ton-scale 0ββexperiment be carried out, and resources are available. • Discussion with HEP suggests that one approach could be an NSAC subpanel with members from NP and HEP to consider DBD R&D and downselect criteria. The subpanel could consider U.S. (pre-conceptual) R&D proposals for next generation experiments, in the context of related international planning efforts and report on: • Merit of U.S. pursuing a next generation double beta decay experiment in current international • landscape • Identify potential candidates of next generation experiments – description, Status of R&D, • remaining risks, priorities for future R&D • Down select criteria for an internationally competitive experiment, including a sensitivity • goal • These thoughts are formative for strategic planning purposes only at this point. As always, input from the community is welcome RHIC User Meeting, June 27, 2013
Other News: The National Defense Authorization Act for FY2013 and NSAC (H. R. 4310— 581) (4) PUBLIC PARTICIPATION AND REVIEW.—The Secretary shall— (A) develop a program plan and annually update the program plan through public workshops; and (B) use the Nuclear Science Advisory Committee to conduct annual reviews of the progress made in achieving the program goals and make recommendations to improve program effectiveness. NP/ IDPRA (the Isotope Program) is considering the most effective means to propose for addressing this Congressional direction. A concept being considered is to empanel a new NSACI subpanel to carry out the directed assessment as well as an assessment of the status and progress in addressing isotope needs broadly. As always, feedback from the community is welcome. RHIC User Meeting, June 27, 2013

New Charge Given to NSAC on Future Facilities Needed for SC’s Mission From: W. F. Brinkman Director, Office of Science I am writing to present a new charge to each of the Office of Science Federal Advisory Committees. I would like each Advisory Committee to help us with an important task—the prioritization of proposed scientific user facilities for the Office of Science. To meet a very compressed timetable, we will need your final report by March 22, 2013. This charge derives from Administration efforts to improve the efficiency, effectiveness, and accountability of government programs and requirements of the Government Performance and Results Modernization Act of 2010. In order to improve the agency’s performance, and in compliance with this Act, DOE has established several Priority Goals, including the following goal for the Office of Science: Goal Statement: Prioritization of scientific facilities to ensure optimal benefit from Federal investments. By September 30, 2013, formulate a 10-year prioritization of scientific facilities across the Office of Science based on (1) the ability of the facility to contribute to world-leading science, (2) the readiness of the facility for construction, and (3) an estimated construction and operations cost of the facility.
