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.

 Similar Town Meetings have been held for various
departments within Jefferson Lab
Summary Users Town Meeting March 16, 2012
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

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?

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 tagged photon beam to produce η’s.
2. Further reduce the p→ 00p and other combinatory backgrounds by
detecting recoil p with GlueX detector
3. Upgrade FCAL with PbWO4 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
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 PbWO4 crystal calorimeter to 1x1 m2 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 Mx (5 – 120) MeV

high resolution in invariant mass (0.84 MeV @ MX = 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)

A Tracking Trigger for CLAS12
Mac Mestayer
 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

 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.

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 community 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
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 ???
