12 GeV Upgrade
After completion of the beam run to demonstrate the Key Performance Parameter (KPP) for the Hall B scope of the 12 GeV Upgrade project, the hall has been busy preparing for the arrival of the Solenoid magnet. This activity requires a temporary de-installation of some of the detectors that were installed for the KPP demonstration. There will be an increase in overhead work during this preparation period.
Hall C is getting ready for the Hall C KPP demonstration beam run in March. The Q3 quadrupole magnet is cold and power testing is well underway. Cool down of the Dipole magnet is nearing completion, and low power testing will start in a few days. The Hall C beam line has been installed with the assistance of the Survey and Alignment group.

Publications Training Offered
If you’re new to the lab or are writing your first journal article or proceedings paper, the next Publications Training and Refresher course is for you! This 45-60 minute course will be held on Friday, Feb. 24, at 10:00 a.m. in CEBAF Center room F224-225. After this session, you will be prepared to:
These steps are required for Jefferson Lab's compliance to the Department of Energy's Public Access Plan. If you plan to attend, let Kim Edwards know by emailing firstname.lastname@example.org no later than Thursday, Feb. 23.
Nominations Are Being Accepted for the 2016 JSA Thesis Prize
Applications Being Accepted for 2017 HUGS Program at JLab
Applications are being accepted through March 10 for the 2017 Hampton Universities Graduate Studies (HUGS) program to be held at Jefferson Lab in Newport News, Va.
With support from the U.S. Department of Energy and Jefferson Science Associates, the 32nd Annual HUGS Program is scheduled to run from May 30 to June 16. Students will arrive on Monday, May 29 and depart on Saturday, June 17.
The HUGS Program is a summer school designed for experimental and theoretical nuclear and particle physics graduate students who have finished their coursework and have at least one year of research experience in these fields. Students who are well into a research project are also encouraged to apply. The program is simultaneously intensive, friendly, and casual. All lecturers are internationally renowned and leaders in their fields. Students will be housed on site at JLab, and there will be many opportunities to interact with lab staff, as well as the lecturers, other graduate students and visitors. Acceptance into the program is competitive.
The 2017 school will focus on experimental and theoretical topics of high current interest in strong interaction physics. In particular, students will receive insight into the physics to be studied at Jefferson Lab and at a future Electron-Ion Collider, as well as related topics of interest in nuclear and particle physics.
To apply, visit http://www.jlab.org/hugs/. Submit along with your personal data, a request for consideration of acceptance into the program, and arrange for one letter of recommendation (ideally from your Ph.D. advisor) to be separately sent in. Submission received before March 10 will automatically place the student in the standard fellowship competition. Students will be notified of acceptance by March 24.
Center for Theoretical and Computational Physics
A new analysis <arXiv:1701.09170> of the polarization asymmetry AN in p↑p → π X is presented within the collinear twist-3 factorization formalism. The latest extractions of the Sivers and Collins transverse momentum dependent (TMD) functions with TMD evolution are used to compute contributions to AN. Data from RHIC on AN will help to constrain high-x behavior of the transversity distribution, and future semi-inclusive deep-inelastic scattering data from Jefferson Lab will provide important constraints on the Sivers and Collins TMD functions.

Environment, Safety, Health and Quality
The Jefferson Lab Worker Safety Committee is empowered to promote and continuously improve workplace safety at the lab. The committee provides JLab management with working level feedback, ideas, and recommendations for improving safety laboratory wide. The committee also provides safety stakeholders - employees, subcontractors, users - with the opportunity for communication of their issues and concerns. This committee is not intended to bypass existing procedures and processes. Rather, it serves as a vital communication link for highlighting workforce safety issues and concerns and as a means for ensuring that improvement actions of interest to the workforce are addressed.
Committee members have direct access to the Director's Safety Council, or the Associate Director for ESH&Q anytime they deem it necessary. The WSC committee chair or vice chair brief the DSC at the quarterly meetings.
