Jefferson Lab Weekly Briefs
April 16, 2014
12 GeV UpgradeAt the request of DOE's Office of Nuclear Physics, Stephen Meador, Acting Director of the Office of Project Assessment in DOE's Office of Science, convened a team of 16 experts and eight observers in an Independent Project Review of the 12 GeV CEBAF Upgrade Project at Jefferson Lab April 8-10. The purpose of the review was to assess all aspects of the project, including technical, cost, schedule, management and ES&H. The review team provided valuable feedback in all areas and a total of 12 specific recommendations in the areas of superconducting magnets and project management. The committee congratulated the 12 GeV Team on the significant progress made in the accelerator and experimental hall detectors, as well as the project’s safety record and lab implementation of the Accelerator Readiness Review and commissioning processes.
PhysicsJSA Sabbatical and Research Leave Support at Jefferson Lab
The JSA/JLab Sabbatical and Research Leave Support Program enhances research opportunities for faculty through access to Jefferson Lab facilities and interaction with Jefferson Lab researchers and users, strengthens the teaching and research capabilities of universities through faculty involvement, and strengthens the research programs of Jefferson Lab by attracting "new blood" and integrating university faculty members in the lab's programs. JSA will award living expenses up to $1,500 per month for up to twelve months to qualified faculty members to relocate to the Hampton Roads area to conduct full-time research at Jefferson Lab while on an approved sabbatical or research leave. For eligibility and application information, see the JSA website. Application deadline in June 2.

Records and Information Management Month Fact of the Week
Leaving the lab? JLab Records Management provides a list of activities employees who are departing the lab should review to ensure their records are adequately protected and transferred to their supervisor or co-worker. Review the information at this link.
RIM Trivia Question of the Week
The correct answer to last week's question was "evaluated or summarized data." There were no correct answers last week, so this week we will give away two Starbucks gift cards to two randomly selected individuals who provide the correct answer to this trivia question: One of the patron saints of archivists, this individual was executed in the 3rd Century by being roasted on a large gridiron. He is also the patron saint of librarians, deacons and cooks. All responses must be received at firstname.lastname@example.org by noon on Friday, when a drawing will take place of all correct answers. Two people will each win a Starbucks gift card! (Winners will be notified via email no later than 5 p.m. Friday following publication. Limit one gift card win per person.)
Center for Theoretical and Computational Physics
Amplitude analysis of two-photon production of ππ and KK, using S-matrix constraints and fitting all available data, including the latest high statistics results from Belle, yields a single partial wave solution up to 1.4 GeV. The two-photon couplings of the σ/f0(500), f0(980) and f2(1270) are determined from the residues of the resonance poles. Thanks to the very recent construction of a dispersive framework for Light-by-Light reactions, the results presented in the new analysis will bring a new precision to the on-going calculation of the hadronic contribution to the anomalous magnetic moment of the muon. Reducing these uncertainties is essential if new experiments planned at Fermilab and J-PARC are to deduce hints of physics beyond the Standard Model that can compete with a series of Jefferson Lab experiments, such as Q-weak and APEX.
In the last six weeks, the Installation and Vacuum groups completed their 12 GeV beam transport work. This work included quadrupole girder swaps in the tunnel sections to Halls A, B and C. This work also involved beam pipe installation with leak checking.
The Cryogenics group provided installation with two skilled welders to work the skids and piping for the Hall D dump, and they were instrumental in completing this work on schedule.
Facilities Management and LogisticsJefferson Lab Parking Lots to Be Closed April 26-27 for Markings Painting
On Saturday, April 26, and Sunday, April 27, road traffic markings and parking lot markings are scheduled to be re-painted. If the weather conditions are not favorable that weekend, the work will be re-scheduled for the following weekend. Parking will be limited onsite to specific areas. For a list and map of available parking areas during the work, see the full announcement.
The subcontractor will provide traffic control to ensure the safety of its crews while also allowing traffic to continue to flow in and about the lab. Awareness of their presence as well as adhering to the traffic controls is required. Refer to the attached PDF to see the scope or the project. All road traffic markings and highlighted parking areas are scheduled for re-painting. Thank you for your attention to this work.

AnnouncementsJefferson Science Associates Minority/Female Undergraduate Research Assistantship
Jefferson Lab is seeking candidates for a research assistantship. JSA will provide funds to support the student at the university during the 2014-2015 academic year. This project is supported by the JSA Initiatives Fund Program, a commitment from the JSA owners, SURA and PAE Applied Technologies. Initiatives Funds support programs, initiatives, and activities that further the scientific outreach, promote the science, education and technology of the Jefferson Lab and benefit the Lab’s extended user community in ways that complement the lab’s basic and applied research missions. Nominations will be accepted through May 2. For more information, visit the website.

Dark Forces, Dark Matter, and the GeV-Scale Discovery Frontier
The search for dark matter and new forces mediated by sub-GeV particles with very weak coupling to matter (“dark forces”) is an emerging frontier in fundamental physics. Philip Schuster, a Faculty Member of the Perimeter Institute for Theoretical Physics and a SLAC Research Associate, will present the theoretical motivations for dark forces and their possible connections to dark matter and the anomalous magnetic moment of the muon. He will also discuss strategies, results, and prospects for searches at high-energy colliders, flavor factories, and dedicated fixed-target experiments, focusing particularly on the near-term program of searches for dark forces at Jefferson Lab, including APEX in Hall A and HPS in Hall B. He will also briefly describe opportunities to directly search for dark matter at Jefferson Lab in the future. The colloquium will be held on April 22 at 3 p.m. in the CEBAF Center auditorium.

If you have property or property validation process questions or concerns, contact the Property office at x7348, Monday – Friday, 8 a.m. - 4 p.m. or email email@example.com. Every person who has one or more Jefferson Lab keys must also validate each key issued to them. If you have any non-essential or non-functional lab keys, return them to Dennis Merritt, Mail Stop 28G. If you have questions about the key validation process, contact Dennis Merritt.
Student Projects, Volunteer Mentors Needed for High School Interns
Six outstanding high school students have been selected to participate in the lab's High School Summer Honors Program, which will be held June 23 - Aug. 1. Critical to the success of their internship experience are projects for the students and mentors who can oversee one or more students as they carry out their work. The students are currently in the 11th and 12th grades and have expressed interest in pursuing scientific and technical careers. Lab scientists, engineers and other technical managers who are interested in serving as a mentor to high-achieving high school students and have a project, or any number of small projects that can be accomplished over the summer, are asked to contact Brita Hampton with a description of the work to be assigned. If you have questions email or call her at x7633. She needs ideas or proposals by May 1.
