12 GeV Upgrade
Construction of the first two of the five magnets for the Hall C Super High Momentum Spectrometer (SHMS), namely the horizontal bend (HB) dipole and Q1 quadrupole magnets, is now in the latter stages. The HB magnet has had the inner multi-layer insulation (MLI) added to the helium vessel, followed by the attachment of the copper thermal shield, which will be held at liquid nitrogen temperature during operation, and the outer MLI then added. The first several pieces of the outer vacuum cryostat have been welded together. Q1 has been placed inside the vacuum cryostat and had the final instrumentation and cryogenics control reservoir added. Unfortunately, a small leak in the nitrogen circuit has appeared, requiring an intervention to repair it. The first production coil for the dipole magnet has been epoxy impregnated and removed from the winding mandrel, and the second coil is being readied. Winding of the first two coils for the Q2 magnet is well underway and will be followed by the winding of the Q3 magnet.
Reminder: Users Group Satellite Meeting at DNP
The Users Group will hold its Satellite Meeting at the annual DNP Fall meeting, located in Hawaii at the Hilton Waikoloa Village. The meeting will begin at 4:30 p.m. on Thursday, Oct. 9, in the Kings I room.

Center for Theoretical and Computational Physics
The observation of the d - u flavor asymmetry in the proton has been one of the most stimulating results in hadronic physics of the past two decades. A new paper computes this asymmetry in chiral effective theory, including both nucleon and Δ degrees of freedom, placing the calculation on firm theoretical footing in QCD. In addition to the distribution at positive quark momentum fractions x, corrections to the asymmetry are also found to arise from pion rainbow and bubble diagrams at zero momentum, which have not been accounted for in previous analyses.

Environment, Safety, Health and Quality
Resolving ES&H Concerns
To ensure your welfare and productivity, Jefferson Lab has several mechanisms for employees, or anyone who comes into contact with the lab, to report issues potentially affecting the safety of workers, visitors, lab neighbors or the environment without fear of retaliation or reprisal. ES&H Manual Chapter 2310 lists a variety of mechanisms for resolving and reporting ES&H concerns and for preventing similar concerns from occurring in the future.
Here is a list of the options you have for resolving an ES&H concern:
If possible, resolve the ES&H concern yourself.
If you are unable to resolve the concern yourself, refer the concern to your supervisor and management chain using the mechanisms outlined here.
You may also consult your Safety Warden, Division Safety Officer, your representative to the Worker Safety Committee, or contact an ESH&Q staff member directly for any ES&H concerns you may have.
If you would like to remain anonymous, or if you feel that it is more appropriate, use Jefferson Lab’s Employee Concerns Program.
If one or more of the above steps have not resulted in resolution of the concern, or if you feel that it is more appropriate, you may also use the formal DOE Employee Concerns Management System hotline at 800-676-3267.
Or use this link to the form for the DOE's Differing Professional Opinion (DPO) process also found in DOE Order 442.2 or by calling or emailing the DOE DPO Manager, Scott Davis, at 301-903-9641.
The DOE DPO process ensures that all JSA employees and contractor employees have the right to report environment, safety, and health technical concerns that have not been resolved through routine work processes.
Once your concern has been addressed, communicate any lessons learned to your staff, co-workers, supervisors and your Division Lessons Learned Coordinator. ES&H Manual Chapter 2310 offers more information on concern resolution.
JLab SOTR Training Registration Ends Oct. 9

Anyone who will be tasked to serve as a SOTR on any project at Jefferson Lab is required to attend this training. Attending this training is one part of the Jefferson Lab certification requirement for all SOTRs. To attend, register online by 5 p.m. Thursday, Oct. 9, or contact Kathleen Jones at x5139.
Red Cross Blood Drive Scheduled for Oct. 31
The next American Red Cross Blood Drive will take place Friday, Oct. 31, 10 a.m.-4 p.m. in CEBAF Center room F113. New and repeat donors are encouraged to attend. All those who donate will be entered into a drawing for prizes from the American Red Cross. To schedule an appointment, visit redcrossblood.org and enter Sponsor Code: TJNAF. You can also contact Johnie Banks, firstname.lastname@example.org or x7539. Visit the website for donation eligibility requirements.
Discount Entertainment Tickets Available

To sign up, see Mike Zarecky, in the Technology and Engineering Development building, room 2500/19. You can find more information on the Jefferson Lab Golf League page.
Annual Performance Appraisal Process Underway
The Jefferson Lab performance review cycle is Oct. 1 - Sept. 30 each year. This year's performance appraisal process officially began on Sept. 29. All self assessments should be completed by Oct. 14. For more information, see the full all-staff memo.
Fitness Room Now Open
The Fitness Room in the Technology and Engineering Development Building (TED Bldg. 55) is now open 6 a.m. - 8 p.m., seven days a week.
