JSA 2015 Initiatives Fund Awards Announced
The Initiatives Fund Program made new awards for 31 projects. Half of the award funds support the education and outreach programs at the Jefferson Lab. The remaining awards support post doc career development, other Lab programs, Jefferson Lab users initiatives and activities, and several topical science meetings. See the full list on the JSA website.

JSA Is Accepting Nominations for 2015 Outstanding Nuclear Physicist Award
The Outstanding Nuclear Physicist Award recognizes individuals who have made outstanding and sustained contributions, including technical achievements, to experimental and/or theoretical research related to the nuclear physics program at the Jefferson Lab. The biennial award consists of a certificate and a $10,000 honorarium, presented to the honoree at the Jefferson Lab Annual Users Group meeting. Travel for the recipient is provided by JSA. Nomination packages are due by Feb. 2, 2015. More information, as well as nomination package instructions, can be found on the JSA website.

Center for Theoretical and Computational Physics

A new article gives an extended description of a recent coupled-channel scattering analysis from lattice QCD, where the coupled π-K, η-K system was considered, and scattering amplitudes were obtained for the first three partial waves. The amplitudes were analyzed to understand their pole structure and couplings, and a pattern of strange resonances was found that was similar to those seen in experiment. This work represents a vital step in developing the techniques to understand, within QCD, the highly excited resonances in the hadron spectrum.

Environment, Safety, Health and Quality

Candle Safety
If you put up your holiday decorations this month, be especially careful with your candles. Better yet, use flameless candles, which now come with remote controls, scents, timers, rechargeable batteries, and in many different sizes. According to the National Fire Protection Association, candle fires increase during the winter holidays, because people burn candles more, and they burn them near decorations. When you use real candles, follow these safety tips:

  • Keep candles at least 12 inches from anything that can burn;
  • Keep candles out of the reach of children and never leave a child unattended in a room with a candle;
  • Use sturdy candleholders that won’t easily tip over;
  • Put candles out before they burn down completely to the holder or container; and
  • Never use a candle in a home where anyone uses an oxygen tank.

Computing and Networking Infrastructure

Zimbra Email and Calendar Upgrade
The Zimbra email and calendar system will be upgraded on Jan. 2, 2015. During the upgrade, there will be intermittent outages as systems are upgraded and rebooted. Current plans are to start the upgrade at around 8 a.m. All email should be back up and stable by 8 p.m. If you have any questions or concerns regarding this upgrade, contact the IT Division Helpdesk at or x7155.


Freestock Item Reduction and Stored Property Review
Next week, Freestock items will be significantly reduced. The last chance to review and select items before they are processed for donation or disposal is the first week of December. Stop by the Stockroom, located in room 108 in the Experimental Equipment Lab (Bldg. 90), to check out the items. Do not drop off any items without approval from the Stockroom personnel. For assistance with Freestock, contact Lawrence Ferbee (x6297), Angela Stanley or Christian Whalen.

Property items may only be stored for one year, and then stored items must be reviewed per the "Equipment Held For Future Projects" guidance in the Property Manual. Property items being stored as "Spares" also must be reviewed for their relevance and condition needed for current operations. Once you review your stored and spare items and determine that continued storage is necessary, you may fill out and submit the renewal forms online. For assistance with this process, contact Christian Whalen, x5899.

Upgraded Vending Machines Deployed
In October, the aging vending machines that had been in L203A off the CEBAF Center mezzanine were removed. The snack and beverage vending machines in the F wing, located in Vending room F204, have been upgraded to allow the use of credit or debit cards. The employee announcement bulletin boards that were in L203A have also been moved to F204.

In the ARC building, the vending machines on the third floor have been removed, and the remaining vending machines on the first floor have been upgraded to allow the use of credit or debit cards.

Holiday Party for Jefferson Lab Children and the Young at Heart
The JAG Holiday Party is scheduled for Saturday, Dec. 6, 10 a.m.-1 p.m. in the CEBAF Center lobby. All employees, contractors, users and their children are invited. Families are encouraged to bring a new, unopened toy for the U.S. Marine Corps Reserve's Toys for Tots program. Get your picture taken with Santa Claus, who plans to drop by with the snow dogs, Nikko and Tally. (Owners Dan and Kim Young are members of the JAG Dog Training Club, and Nikko and Tally are trained service dogs). Come and enjoy holiday-themed games, crafts and light snacks. All children must be accompanied by an adult.

Volunteers Needed to Help With the Children's Holiday Party
Volunteers are needed to help with the JAG holiday party. Sign up online today. Positions include:

  • Craft-Table Monitors – All crafts and supplies are provided;
  • Game Helpers – Monitor participants and hand out prizes;
  • Snack Area Elves – Replenish platters and general area maintenance; and

Toys for Tots Toy Drive
Jefferson Lab will again participate in the U.S. Marine Corps Reserve's annual Toys for Tots toy drive. Bring your new, unwrapped toy donations for children 1-12 years old. Collection boxes are available near the main entrances of CEBAF Center, MCC, SSC, ARC and TED Buildings. The toy donations will be delivered to the Marines on Dec. 6 at the JAG Children’s Holiday Party.

Mobile Mammography Comes to JLab
The Sentara Mobile Mammography Unit will be here at Jefferson Lab on Dec. 11, 9 a.m.-2 p.m. Mammography detects breast cancer and The American Cancer Society recommends scheduling your first or baseline mammogram at age 40. It only takes 15 minutes! This service is open to all employees as well as their family members or friends as personal health insurances will be billed. To make an appointment, visit and find Mobile Mammography Screenings under Screenings and Events or call 1-800-SENTARA (736-8272).

Ready, Set, Hang Those Decorations
The JAG is sponsoring a Holiday Office Door/Cubicle Decorating Contest. Prizes will be awarded to Best Decorated, Most Original, and Silliest. All employees, users and contractors with an office or cubicle may enter the contest (individuals or groups). Include your name(s), building number and office/cube location. Judging will take place Thursday, Dec. 18. Winning entries will be announced Friday, Dec. 19. Decorations may go up as early as Dec. 1 and should be taken down by Jan. 6. Decorating materials must be fire resistant and only UL-approved lighting/electronics may be used. No unwrapped food items are allowed. To enter, email JAG Chair Mary Jo Bailey by COB Dec. 16.
