An important issue in low-energy nuclear weak transitions is whether the nucleon axial coupling constant gA is quenched in the nuclear medium relative to its value in vacuum. Shell-model calculations indicate that a quenching of gA ranging from 20 percent in light nuclei to 30 percent in heavy nuclei is needed in order to reproduce observed beta-decay and electron-capture rates in these systems. However, a new study based on realistic nuclear interactions and axial currents, and carried out with quantum Monte Carlo methods, shows that this problem be may be partially resolved by correlation effects, which are ignored in the shell-model approach.

Announcements

Give Blood at Jefferson Lab on Oct. 13 and Enter to Win a Gift Card Shopping Spree!
Following the tragic shooting in Las Vegas, the American Red Cross provided more than 450 additional blood products to local hospitals. The American Red Cross is very grateful to all the generous donors who help keep the shelves stocked with life-saving blood products. The next American Red Cross Blood Drive will take place at Jefferson Lab 10 a.m.-4 p.m. on Friday, Oct. 13 in CEBAF Center room F113. Appointments may be scheduled at redcrossblood.org – use sponsor code TJNAF. Also, all presenting donors during October (Oct. 2-31) will be entered in a sweepstakes to win one of three $1,000 gift card shopping sprees. New and repeat donors are encouraged to participate in the Oct. 13 blood drive. Walk-ins are welcome. For more information and links, see the full memo.

Jefferson Lab Unveils New Intellectual Property System
Over the past few months, Jefferson Lab has been transitioning to a new intellectual property management system. Now, the transition from Inteum to the new IP Folio system is complete. This new system allows inventors to submit and track their invention disclosures through the entire process, from disclosure through patenting and commercialization. The first training session on using the new system will be held 1-2 p.m. on Friday, Oct. 13, in CEBAF Center room F326-327. Additional sessions will be scheduled as needed. You can access the new system now via the Technology Transfer webpage. If you have any questions or problems with the new IP Folio system, contact Delisa Stanfield at x7941 or Kari Heffner at x5814 for assistance.

Colloquium: Inclusion Drives Innovation
JSA is excited to welcome Dr. Jane Fernandes, President of Guilford College, as she shares her unique experience in a colloquium on Oct. 19, at 1:30 p.m. in the CEBAF Center auditorium regarding the personal challenges she has encountered and also offer ways to build a more inclusive work environment. Fernandes is the nation’s first deaf woman to lead a college and the first female President of Guilford College. For more information, see the full memo.

Volunteers Needed for 15-Minute Role-Model Visits With BEAMS Students
Jefferson Lab’s BEAMS program – Becoming Enthusiastic About Math and Science – for fifth-grade students is ramping up for the new school year. An important part of the BEAMS experience is Role Model Visits; and Science Education staff is seeking lab volunteers to provide these 15 minute Role Model visits with the students. During the visit, the volunteer discusses their job, education and job training with 12-15 students. For more information and to volunteer, see the full memo.

Exploring the Exotic World of Quarks and Gluons at the Dawn of the Exascale
As nuclear physicists delve ever deeper into the heart of matter, they require the tools to reveal the next layer of nature’s secrets. Nowhere is that more true than in computational nuclear physics. A new research effort led by theorists at Jefferson Lab is now preparing for the next big leap forward in their studies thanks to funding under the 2017 SciDAC Awards for Computational Nuclear Physics.

Calling All Veterans: You're Invited to Participate in the Veterans Day Recognition Display
In recognition of Veterans Day, veterans of military service are invited to submit a photo of themselves in uniform for inclusion in a collage to be displayed in CEBAF Center prior to Veterans Day. This will be similar to the one displayed the past years. If you submitted a photo in the past, the photo will be used again this year with the information you previously provided. If you want to submit a new photo, feel free to do so. Submit photos to Mike Robbins by Nov. 3. Remember to include your full name, branch of service, and years of service. If you do not have a digital copy of your photo, employees can bring in a picture to CEBAF Center, room C222 to be scanned. For more information, contact Mike Robbins at mrobbins@jlab.org or x7617.

Jefferson Lab in the News
Jefferson Lab’s completion of the 12 GeV Upgrade is beginning to garner coverage. So far, articles on the completion have been published in Physics World and the local Daily Press.
 

Environment, Safety, Health and Quality

Fire Protection
Jefferson Lab’s Fire Protection Program is outlined within the ES&H Manual Fire Protection Supplement. It outlines the lab's fire protection and suppression systems and the capabilities consistent with the “highly protected risk (HPR)” status designated by the insurance industry. HPR status requires adherence to the highest quality risk mitigation tactics, where both the frequency and severity of loss is addressed and mitigated using installation, smoke alarms, water hydrants, and sprinkler systems. Jefferson Lab’s Fire Protection Program provides procedures and information necessary to ensure safety. The objectives of the program are:

  • Minimize the likelihood and consequence of occurrence of a fire related event;
  • Provide a level of safety protection consistent with “HPR” class of industrial risks; and
  • Meet or exceed the requirements of DOE Order 420.1C Facility Safety; DOE-STD-1066-2012 Fire Protection using a graded approach for a non-nuclear facility and for leased facilities; and related DOE directives.

Incorporating fire safety into facility planning and operations, and performing maintenance activities minimizes the risk of loss from fire and its related hazards. Everyone at Jefferson Lab plays a role. If you have questions regarding this important safety program, contact Tim Minga at x7310.

Computing and Networking Infrastructure

IT Maintenance Period Set for Tuesday, Oct. 17
The IT Division has scheduled a maintenance period for 5-10 p.m. on Tuesday, Oct. 17. During this time, the VDI environment will be down while the underlying management environment is upgraded. VDI should be back up and available no later than 10 p.m. Updates to Core Common User Environment software, including Acrobat Reader, will be released to all Windows systems. Windows and Linux patches will be released to all CUE-managed systems. Plan on rebooting your desktop system no later than Friday, Oct. 20, to finalize patch installations. If you have any questions or concerns about the planned maintenance, contact the IT Division Help Desk at helpdesk@jlab.org or x7155.

Changes to Lab-Provided Cell Phones and Data Cards
Starting this month, staff who carry lab-provided cell phones or cellular data cards will need to have them re-approved annually. This renewal process is being undertaken to certify the need for the phones on an ongoing basis and manage costs associated with telecom contracts. If you carry a lab-provided phone, you will receive an email asking you to complete an online renewal form in the coming weeks. You will need to complete the form to avoid an interruption in service. If you have any questions or concerns about this process, contact the IT Division Help Desk at helpdesk@jlab.org or x7155.

Adobe Products End of Life
Through scanning of Jefferson Lab-managed systems, the IT Division has discovered numerous outdated Adobe products on-site. These outdated versions are a security risk and should be replaced as soon as possible. If you have an Adobe product installed on your Jefferson Lab system, visit Adobe's End-Of-Life page and search for your product name and version number. This information can be found in the Help menu of your Adobe product. All Adobe products that have reached their 'End of extended support' date should be replaced.

For Adobe Reader, you can install the supported version on your Windows machine from the Control Panel under Programs and Features, 'Install a program from the network'. All other Adobe products that were purchased, and are associated with a license key, must be purchased again if they are beyond their support date. Please visit Adobe's product catalog webpage - http://www.adobe.com/products/catalog.html. This purchase should be made with a Jefferson Lab credit card, or you can submit a Purchase Request (PR) with the appropriate product name and version number. If you have any questions or concerns about this replacing your end-of-life Adobe products, contact the IT Division Help Desk at helpdesk@jlab.org or x7155.
