February 22 Briefs Excerpts: 

12 GeV Upgrade - Hall B Update 
The Torus magnet for CLAS12 was brought back down to liquid helium temperature at the end of January to prepare for the CLAS12 Key Performance Parameter beam commissioning run reported recently. The magnet operated without incident for the entire run. It was then kept at 4 Kelvin for two weeks to gain operational experience with the cryogenics and make incremental improvements to the control loops. You can read about the progress made on the Solenoid magnet in the full JLab Weekly Briefs document: https://www.jlab.org/news/briefs/jefferson-lab-weekly-briefs-february-22-2017 

Physics - Hall A Update 
Hall A has been able to begin an opportunistic science run for Experiment E12-14-012, "Measurement of the Spectral Function of 40Ar through the (e,e2p) Reaction." This data will provide the only available high-statistics sample of electron scattering single nucleon knockout data for Argon, experimental input indispensable to constructing the spectral function. Besides yielding previously unavailable information on nuclear structure and dynamics, this fundamental information is needed to achieve a quantitative description of neutrino-nucleus cross sections in the kinematic regimes relevant to upcoming and future neutrino experiments, such as the Deep Underground Neutrino Experiment (DUNE). In addition, the analysis of the (e, e'p) data will promote further theoretical developments, such as the description of final state interactions, necessary for the correct interpretation of events collected by these neutrino experiments. 

Physics - Hall D Update 
The first physics run of GlueX is underway in Hall D. The accelerator performance is good. An 11.7 GeV electron beam has been delivered to the Tagger Hall, where it interacts with a thin diamond crystal and radiates high-energy photons, linearly polarized in the range of 8-9 GeV. The collimated photon beam is delivered to the liquid hydrogen target of the Hall D solenoidal spectrometer. Selected interactions are recorded at a rate of about 30 kHz. It is an exciting time for the GlueX Collaboration, which met last week at Jefferson Lab for the regular trice-year meeting. 

JAG Seeks Design Ideas for 2017 JLab T-shirt Contest 
The Jefferson Lab Activities Group is seeking entries for the annual T-shirt design contest. Your idea could become the winning design for Jefferson Lab's 2017 T-shirt! New ideas and previously submitted designs are welcome. The winning design will be unveiled at the lab's annual Run-A-Round event, scheduled for May 17. Submit your design online via the JAG webpage by close of business on Friday, March 17. Design requirements and more information may be found in the memo: https://www.jlab.org/memo/jag-seeks-design-ideas-2017-jlab-t-shirt-contest 

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 a.m. in CEBAF Center room F224-225. If you plan to attend, email Kim Edwards at kindrew at jlab.org no later than Thursday, Feb. 23. 

Golf League Forming for 2017 Season; Interested Golfers to Meet on Feb. 23 
The Jefferson Lab Golf League is open to all current staff, retirees, users, and their spouses. All levels of play and weekly availability are welcomed. A 2017 organizational meeting will be held on Thursday, Feb. 23, in CEBAF Center room F113, noon -1 p.m.
