Norbert Holtkamp SLAC National Accelerator Laboratory January 2016 9 Page 9 Executive Summary A day-one physics program in the field of strong quantum chromodynamics (QCD) was presented. Highlighted were studies of gluonic meson excitations, the nucleon spin puzzle, the 3D nucleon structure, parity-violating experiments, precision nuclear structure studies, tests of the standard model and a limited search for dark photon candidates. Overall, the planned 12 GeV physics program was judged by the panel as outstanding and highly competitive in the context of international activities. There is a well formulated and prepared series of physics experiments which should yield high impact, visible results in the first few years. The majority of the research topics of the Theory Center are in support of the experimental program at CEBAF. A fruitful collaboration exists between experiment and theory from the proposal stage up to data analysis. The international outreach and expansion of the role of the Theory Center is commendable. Development of milestones for amplitude construction relevant to spectroscopy experiments, extraction of Generalized Parton Distributions (GPDs) and Transverse Momentum dependent Distributions (TMDs) from experiments, and for lattice gauge computations concerning the production of hybrid mesons relevant to Hall D is strongly encouraged. January 2016

10 Page 10 Executive Summary Contd Accelerator performance continues to be world class. The CEBAF delivered 10.5 GeV beam to Hall D for commissioning and simultaneously to Halls A and B. Beam performance at 10.5 GeV is generally better than required. A well-planned transition to operation following completion of the 12 GeV upgrade project is essential for JLabs early physics programs to succeed. Construction and eventual installation of a spare C100 cryomodule was identified as a means to mitigate risk and ensure machine reliability. A proposed capability to deliver beam to all 4 halls simultaneously is an important improvement to provide more beam time to the users. JLab is engaged in a number of high profile and important DOE projects which commit a substantial fraction of the staff. The cryogenic design and engineering team is the premier group in the U.S. and is doing an impressive job covering multiple projects (Linac Coherent Light Source II, FRIB, and 12 GeV) with lean staff. Management should work to develop new talent to maintain this important skill set for the U.S. and provide expertise for other DOE laboratories. The injector group was viewed as being at the top of the field for producing parity-quality polarized electron beams. The Laboratory was encouraged to continue to search for opportunities to develop new missions for the Low Energy Recirculating Facility. The laboratory was also encouraged to search for more external collaborators to help with the development of the Medium energy Electron-Ion Collider (MEIC) design. January 2016 11

Page 11 Executive Summary Contd JLab staff demonstrates leadership and creativity in proposing and shaping the physics program for JLab. The leadership role JLab staff play in the community is evident from the numerous appointments of their staff to important committees that help guide the national program in nuclear science. The user community seems strongly engaged in contributing to both the near- and longterm health of the Laboratory. The Users Group seems reasonably content with the level of communications from the Laboratory regarding scheduling and priorities. JLab management has effectively developed an early physics plan which addresses the challenging multi-dimensional balancing of priorities and early capabilities. Significant risks in development of the HDIce polarized target for the CEBAF Large Acceptance Spectrometer (CLAS12) detector were identified and Laboratory management should consider a decision point at which backup plans are developed. The Laboratory maintains an impressively broad expertise in accelerator design, construction and operation as well as cryogenic engineering. It will be important to have a well thought out succession plan to maintain these standards. It may be prudent for management to take a new look at the relative priorities and timelines of Accelerator Improvement Projects (AIPs) to mitigate of risks associated with maintaining full-energy performance. The JLab commitment to the Linac Coherent Light Source (LCLS-II) cryomodule fabrication involves a significant fraction of available SRF and cryogenic workforce and management will have to carefully monitor and manage the impact of possible delays on 12 GeV operations. The Laboratorys safety record has improved since the peak years of 12 GeV construction. Management is commended for implementing a student safety mentorship program. January 2016 12

Page 12 2015 NSAC Long Range Plan NSAC = Nuclear Science Advisory Committee Advise DOE and NSF on future of Nuclear Physics program every 5-7 years Four recommendations Two initiatives January 2016 13 Page 13 NSAC 2015 LRP RECOMMENDATION I The progress achieved under the guidance of the 2007 Long Range Plan has reinforced U.S. world leadership in nuclear science. The highest priority in this 2015 Plan is to capitalize on the investments made. With the imminent completion of the CEBAF 12-GeV Upgrade, its forefront

program of using electrons to unfold the quark and gluon structure of hadrons and nuclei and to probe the Standard Model must be realized. Expeditiously completing the Facility for Rare Isotope Beams (FRIB) construction is essential. Initiating its scientific program will revolutionize our understanding of nuclei and their role in the cosmos. The targeted program of fundamental symmetries and neutrino research that opens new doors to physics beyond the Standard Model must be sustained. The upgraded RHIC facility provides unique capabilities that must be utilized to explore the properties and phases of quark and gluon matter in the high temperatures of the early universe and to explore the spin structure of the proton. The ordering of these four bullets follows the priority ordering of the 2007 plan. January 2016 14 Page 14 NSAC 2015 LRP RECOMMENDATION II The excess of matter over antimatter in the universe is one of the most compelling mysteries in all of science. The observation of neutrinoless double beta decay in nuclei would immediately demonstrate that neutrinos are their own antiparticles and would have profound implications for our understanding of the matter-antimatter mystery.

We recommend the timely development and deployment of a U.S.-led tonscale neutrinoless double beta decay experiment. January 2016 15 Page 15 NSAC 2015 LRP RECOMMENDATION III Gluons, the carriers of the strong force, bind the quarks together inside nucleons and nuclei and generate nearly all of the visible mass in the universe. Despite their importance, fundamental questions remain about the role of gluons in nucleons and nuclei. These questions can only be answered with a powerful new electron ion collider (EIC), providing unprecedented precision and versatility. The realization of this instrument is enabled by recent advances in accelerator technology. We recommend a high-energy high-luminosity polarized EIC as the highest priority for new facility construction following the completion of FRIB. January 2016 16 Page 16 NSAC 2015 LRP RECOMMENDATION IV

We recommend increasing investment in small-scale and mid-scale projects and initiatives that enable forefront research at universities and laboratories. MOLLER SoLID January 2016 17 Page 17 NSAC 2015 LRP Theory Initiative To meet the challenges and realize the full scientific potential of current and future experiments, we require new investments in theoretical and computational nuclear physics. Computational nuclear theory national FRIB theory alliance Expansion of Topical Collaborations Initiative

Initiative for Detector and Accelerator Research and Development US Leadership requires tools Vigorous detector and accelerator R&D in support of the neutrinoless double beta decay program and the EIC. January 2016 18 Page 18 FY2016 Budget ONP Guidance / FY16 Presidents Budget Request supported ~ 16 weeks running This matched somewhat with some infrastructure work in CHL and the Utilities Infrastructure Modernization project which happened during the summer shutdown

But we would have liked more running in FY16 and tried with Senate and House Omnibus FY2016 Office of Nuclear Physics received $-7.5M with respect to Presidents Request Jefferson Lab share was $-1.5M Better than Senate and even than House marks We are holding running weeks, holding critical staff, squeezing elsewhere FY2017 Letter from 6 Senators supporting Nuclear Physics at LRP level

R&D with aim to further reduce technical risk has been included in the Governors Budget proposal. January 2016 21 Page 21 Land Situation

Long Term Sublease to DOE for VARC/SSC building land secured Use agreement for parking on Plot C2 in final negotiation Sale of Plot C3 for Tech Centre development foreseen MOU with City promising the 17 acres of land needed for future expansion, for example the Electron Ion Collider has been signed January 2016 22 Page 22 Summary The Upgrade Project has made excellent progress with all the magnets compared to one year ago. There is still a lot of work, and continued tension, and attention to the issues but we are very pleased.

ONP Science and Technology review was stellar, we got several comments, which we are treating seriously, but no negative recommendations. The NSAC Long Range Plan Report was a strong reinforcement for our strategy. The EIC appears to be gaining considerable traction. With considerable drive from JSA/SURA, the land needed for continued lab operations, and for eventual EIC or other expansion has been secured. January 2016 23 Page 23
