Enjoy the Holiday Lights with Science
Join Jefferson Lab and other local science and technology institutions at Brooks Crossing on Friday, Dec. 13, as we light the night with free and fun STEM activities.
Read about it here.
 
 

VECTOR CURRENTS IN CHIRAL PERTURBATION THEORY FOR LARGE N_C
A study has been carried out of vector currents in baryons based on the newly-developed effective theory that combines chiral perturbation theory with the large-N_c expansion (N_c is the number of quark colors). The calculation gives results for flavor symmetry breaking by quark masses in charges and magnetic moments, including electromagnetic and weak, as well as for charge and magnetic radii of baryons. The formalism extends to both the SU(3) octet and the decuplet of baryons.

 

NEW MINIMUM RADCON PASSING SCORE  
The Radiation Control department has streamlined the radiation worker online training, printed version study materials and proctored examination materials. The lab has maintained a minimum passing score of 75% for Radiation Worker examinations for the past 20 years. In Jan. 2020, the lab will align our radiological testing requirements with other DOE facilities to increase the minimum passing score on all Radiation Control department examinations to 80%. 

In preparation for the increase in minimum score, the RCD has reviewed all test questions and has updated them for consistency with the new study guide and applicability to required worker knowledge. If you have any questions regarding this new policy, please contact Adam Stavola at x6806.
 



IT DIVISION MAINTENANCE
The IT division is planning a systems maintenance period on Tuesday, Dec. 17, from 5-10 p.m. During this time, there will be an outage of all Management Information System (MIS) services while patches are applied to the backend servers. All MIS services will be back online no later than 10 p.m. The IT division will also release patches to all Windows and Linux desktops and servers. Reboot your common user environment-managed desktop no later than 5 p.m. on Friday, Dec. 20. Finally, there will be short, intermittent outages to central services overnight while servers are rebooted to finalize the patch installation. For questions, contact the IT Division Help Desk at x7155.

 



HOLIDAY SHUTDOWN GUIDELINES
The lab shutdown begins at close of business on Friday, Dec. 20, 2019. The lab will reopen on Thursday, Jan. 2, 2020. Dec. 25, 30, 31 and Jan. 1 are designated as holidays. Be sure to review the full memo to ensure you understand the available leave options during this time. If you have questions about the guidelines, contact your manager.

REMINDER - 401(K) OPEN ENROLLMENT CLOSES - DEC. 13
As a reminder, The 401(k) Group Supplemental Retirement Annuity open enrollment for 2020 is will close Friday, Dec. 13. All elections will be reflected in the Jan. 15, 2020 paycheck. If you wish to make changes to the 5% default amount, those changes must be made before Friday, Dec. 13, at 5 p.m. You can change your contribution amount any time during the year by submitting a new Salary Reduction Agreement form located in Human Resources in the SSC building.

FAREWELL TO MARY LOGUE - ESH&Q ASSOCIATE DIRECTOR - DEC. 11
Please join lab leadership in wishing Mary Logue, ESH&Q Associate Director, congratulations on her upcoming retirement. Mary has served the lab for more than a decade, providing direction and management on behalf of the ESH&Q division. Her last day with the lab will be today, Dec. 11.

Mary was known to open meetings with the chorus, "enter, rejoice and come in," says Bob May, ESH Deputy Director and acting ESH Associate Director. "It set such a positive note for meetings, which was especially helpful with those difficult ones that tend to happen now and again."

"Long time lab employees recognize the significant positive impact Mary has made on advancing our ESH&Q programs and safety culture," COO, Mike Maier added.

"Her job was more than ES&H compliance. Her approach to her work was to build a series of relationships and on the basis of that trust, encourage safe practices and behaviors. This goes beyond compliance and encourages performance," May says.

CHILDREN'S HOLIDAY PARTY PHOTOS
The annual Children's Holiday Party was a great success! The JAG committee would like to thank everyone who came out to the lab to see Santa, make crafts, snack on festive snacks and more last Saturday. Additionally, they would like to offer a very special thank you for all the donations to Toys for Tots. Photos from the event are now up on the JAG webpage.

SERVING UP HOLIDAY CHEER - MOMO's HOLIDAY BUFFET - DEC. 19
Who's ready for another MOMO's all-you-can-eat buffet? On Thursday, Dec. 19, MOMO's will be taking the lab on a festive culinary journey around the world! From mini falafel wraps to pork tenderloin to veggie eggrolls, the MOMO's holiday menu aims to please no matter your taste. Check out the full holiday menu here. For questions, please contact Gaye Davenport at x7246.

INPUT NEEDED - JAN. 9
On Thursday, Jan. 9, the lab will begin an inclusion survey, requesting input from all staff and Users. The lab needs your participation for this to be a success and to ensure we are an inclusive workplace for all. Stay tuned for more information!

UNITED WAY FINAL DONATIONS
This year, Jefferson Lab raised a grand total of $25,450.08 for the Peninsula chapter of the United Way. Your charitable donations will provide direct support for low-resourced persons in our local community. Thank you for your support!

 



EMPLOYEE SPOTLIGHT - JOSH CAMERON - U.S. ARMY RESERVES

Military Appreciation Month may be over, but our gratitude to those who served our country is all year-long. Josh Cameron currently serves the U.S. as a Logistics Officer and a Company Commander of an Inland Cargo Transfer Company for the U.S. Army Reserves. "My favorite part of the job is leading the troops. There is no better feeling than taking care of your soldiers needs, mentoring them and meeting mission requirements. It brings a sense of pride to everyone involved."

Today, he supports the lab as a member of Event Services and the Emergency Management team. "My military experience in logistics, planning and leadership has made me very effective at my job here at the lab," Cameron added.
