12. Users Town Meeting March 16  As part of the ongoing Jefferson Lab Strategic Plan development, we held a Town Meeting on March 16, 2012, for users to bring their ideas and discuss the following issues: –Vision for the Future (5 - 20+ years) –Lost or missed opportunities ? –Required New Initiatives ?  The meeting was held Friday, March 16 2012 (all day) in the CEBAF Auditorium. –12 presentations by users –Well attended –Summary at https://wiki.jlab.org/cugwiki  Similar Town Meetings have been held for various departments within Jefferson Lab

13. 18 The Town Meeting brought together users and Jefferson Lab management to discuss the users’ vision for the longer term future (5-20+ years) of the Lab, as part of the strategic planning exercise presently underway. 12 presentations by users addressed possible new initiatives and directions beyond the base equipment for the 12 GeV era and its already approved experimental program. Seven talks addressed necessary equipment upgrades to maximize the Physics output from experiments with 12 GeV beam in all 4 Halls Summary Users Town Meeting March 16, 2012 All talks have been posted at https://userweb.jlab.org/~kuhn/UGBoD/Town Meeting2012/ https://userweb.jlab.org/~kuhn/UGBoD/Town Meeting2012/

15. Questions Asked Each Town Meeting  Mission Statement of your Division – What is or should be the mission statement of your division?  Scope of Current Activities – What is it that your division does, what is your current scope of work?  Unique capabilities - What facilities/capabilities/expertise does your group offer that is unique, world class?  Synergy – Discuss how you think your division contributes to the missions of other parts of the lab. Can you do more?  Vision for the Future - What do you see your division contributing to/doing in the future? What could you be doing? – 5 year – 10 year – 20 Year – Beyond  Lost or missed opportunities - Were there expansion opportunities/synergies that you missed or that you have not been able to capitalize on? What were they, and what was the obstacle that kept you from realizing that opportunity? Are there lessons to be learned from that experience? Are there likely future opportunities in the same or similar areas?  Required New Initiatives - What research, projects or preliminaries would you need to pursue or put in place to achieve the visions above? This should include internal to the lab as well as external.

17. Summary  12 GeV tagged photon beam with GlueX setup will provide a great opportunity for precise measurements of various η rare decays to test higher order χPTh, C, P and CP symmetry violations, and search for new physics beyond the Standard Model  Propose simultaneous measurements on BR(η →  0  ), BR(η →  0  0 ), BR(η → 3  ), and BR(η →  0  ).  Three experimental techniques will be combined: 1.12 GeV high intensity 1.12 GeV high intensity tagged photon beam to produce η’s. detecting recoil p 2.Further reduce the  p →  0  0 p and other combinatory backgrounds by detecting recoil p with GlueX detector 3.Upgrade FCAL 3.Upgrade FCAL with PbWO 4 crystals  High high granularity calorimeter to reduce the η →  0  0  0 background due to over-lap showers.  Fast decay time to reduce low energy pile-up clusters  High energy and position resolutions to have precise invariant mass and elasticity spectrum for event selection L. Gan

18.  A search experiment is proposed for hidden sector scalar bosons with Hall B tagger in neutral channel decays: X     upgraded Hall B photon tagging facility to 11.5 GeV beam  upgraded PbWO 4 crystal calorimeter to 1x1 m 2 total size  Upgraded tagger will be a good addition to Hall B physics program with CLAS12  Advantages of the proposed experiment: large acceptance range for M x (5 – 120) MeV high resolution in invariant mass (0.84 MeV @ M X = 80 MeV) high detection efficiencies (~20%) relatively low experimental background (charged)  Work in progress for evaluation of sensitivity limits in X-boson parameter space and optimization of experiment (including background studies) Beam dump HyCal PS Dipole Tagger magnet New Dipole #1 11.5 GeV e - beam New Dipole #2 A.

21.  FPGA technology enables flexible triggering schemes for charged tracks  Higher-purity trigger saves tape costs,  New technology reduces maintenance and power costs  Addition of tracking to triggering reduces the load on the downstream DAQ  higher luminosity; shorter data-taking times lower costs, higher statistics, more physics A Tracking Trigger for CLAS12 Mac Mestayer

Watts (Edinburgh U.), and Y. Zhang (JLab) Igor Strakovsky  This is a far-reaching program that will benefit both the coming JLab EIC complex and the resonance-physics program, which is one of the top priorities at the Jefferson Lab.  The second piece is a neutron facility that is critical for the US Energy Program, i.e., for Acceleration Driven System ( ADS ) and upcoming Generation IV Nuclear Reactors.  So we can longer keep the JLab pre-Booster and Linac busy [to use more then ``several minutes” a day], which would be a much more effective use of the MEIC facility, without significant increase of the cost of the JLab pre-Booster and Linac.

33. Future Plans / Ongoing Issues: NSAC Long Range Plan Implementation The first meeting of a new NSAC subcommittee was held on May 15, 2012. The subcommittee has been charged to provide advice on implementing the priorities and recommendations of the 2007 NSAC Long Range Plan in light of projected budgetary constraints and for guidance on developing a plan to implement the highest priority science in the context of likely available funding and world-wide capabilities. The subcommittee used its first meeting to hear presentations from DOE and NSF representatives and to begin setting the agenda for the next meeting, which will mostly focus on presentations from the four major areas of science that were covered in the 2007 Long Range Plan. Also some significant time in the first meeting was devoted to the issue of com- munity input to the process. While the subcommittee is not carrying out a new LRP, it recognizes that the impact of the present effort will be significant for the field. We welcome input from individual members of the community and have a link on the subcommittee website http://cyclotron.tamu.edu/nsac-subcommittee-2012 for DNP members to post comments to the subcommittee. For those interested in using this mechanism, comments will need to be submitted with your name and email address so that they can be approved by a moderator before they are posted. For those of you who are involved in a program at a major US user facility, it may be more appropriate to work through your User Group to provide input to the subcommittee. Other groups may want to 'self organize' in order to have their collective voice heard. Since this is not a new LRP exercise, extended White Papers detailing all of the potential avenues of research will likely not be very useful to the subcommittee. More concise summaries putting the importance of the science in clear language would be particularly valuable. In addition, the DNP Executive Committee has agreed to set aside time at the fall DNP meeting in Newport Beach (likely in conjunction with the Town Meeting) for community input to the process. More information on the Fall Meeting plans will be forthcoming. Bob Tribble NSAC Subcommittee Chair

34. Conclusion  The Board of Directors is busy working for the benefit of the Users, but we can only be effective if you communicate with us  Management is responsive to the users but some areas (e.g., computing and data exchange) may need further improvement.  Please respond to polls at https://wiki.jlab.org/cugwiki. Also, please give us feedback on the NSAC LRP implementation  All spokesperson of experiments that took data during the 6 GeV era are requested to provide “Scientific American” type summaries  Next Users Meeting: May 29-31, 2013 ???
