Postdoc Receives Prestigious International Grant 

Andrea Signori was recently awarded a Marie Sklodowska-Curie Fellowship. The grant is designed “to create a game-changing impact on our society and economy” and allows researchers to conduct research across international boundaries. Read more here . 

				
		
		


EXPERIMENTAL NUCLEAR PHYSICS 
Hall A is preparing to continue the family of high impact tritium experiments. Here, Experiment E12-11-112 will provide a measure of tensor force dominance in short-range correlations, leveraging the mirror nuclei 3H and 3He to provide key information regarding the potential link between short-range correlations and the EMC effect. Experiment E12-15-008 will then use the novel tritium target to measure nucleon-hyperon (baryons involving strange quarks) interactions. The recent observation of ~2 solar mass neutron stars has revealed that our understanding of the nuclear force with hyperons is not satisfactory. 

Hall B has been preparing to continue the CLAS12 run that started earlier this spring. It is the first physics run (RG-A) after the commissioning run in December and January. RG-A will take data for 13 individual proposals, covering topics from searches for exotic hadrons, meson and baryon spectroscopy, 3-dimensional imaging of quarks in transverse space and momentum based on the generalized parton distributions and transverse momentum distributions, and the study of J/psi production and of hidden charm pentaquarks. In parallel, data analyses proceed on data taken during the spring run in preparation for the APS/DNP meeting in October. Many new results have recently been published from CLAS data, including a new paper in the journal Nature on short-range correlations in nuclei. 

Hall C is ready to start Experiment E12-09-011 . This experiment will provide first-ever precision measurements of longitudinal-transverse separated kaon electroproduction cross sections in the deep inelastic scattering regime as a function of momentum transfer. These data will determine if efforts to obtain the spatial extension of the charged pion can be extended as well to the charged kaon, and if kaons can be used to enable 3D spatial tomography of strange quarks within the nucleon. 

THEORETICAL AND COMPUTATIONAL PHYSICS 
For the first time, numerical calculations of the complete cross section have been presented for the production of unpolarized hadrons in semi-inclusive deep-inelastic scattering. The calculations use the Wandzura-Wilczek-type approximation, which systematically assumes that quark-gluon-quark terms are much smaller than quark-quark correlators. The predictions can be tested by data from Jefferson Lab, COMPASS, HERMES and the future Electron-Ion Collider, which will help our understanding of transverse momentum dependent parton distributions beyond leading twist. 
ESH&Q 
Keeping Your Eyes Healthy: Wear sunglasses 
Sunglasses are a great fashion accessory, but their most important job is to protect your eyes from the sun ’s ultraviolet (UV) rays. According to the National Eye Institute, the effect of sun on the eyes can include: 


    * Cataracts, a clouding of the eye’s lens that can blur vision. An estimated 20 percent of cases are caused by extended UV exposure. 
    * Macular degeneration, resulting from damage to the retina that destroys central vision. Macular degeneration is the leading cause of blindness in the United States. 
    * Pterygium, a tissue growth over the white part of the surface of the eye that can alter the curve of the eyeball, causing astigmatism. 
To keep your vision sharp and eyes healthy, purchase sunglasses that block out 99 to 100 percent of both UVA and UVB radiation. 
ENGINEERING 
E-Sign: A Reminder from the Document Control Office 
E-Sign is a workflow process that allows users to import engineering documents into the Document Repository. It is designed to stipulate document details, provide an approval route and secure signatures by watermark. Carefully review documents and mark-ups before uploading your drawings into the repository. Use E-Sign and the Document Repository for signature processing only. For more information, contact Audrey Barron . 



FACILITIES MANAGEMENT & LOGISTICS 
Jefferson Lab On-Site Stockroom Closed Aug. 29-31 
The Jefferson Lab Stockroom will be closed Aug. 29-31 for its annual inventory of stocked items. This closure does not apply to items purchased via Purchase Requisition, so continue to submit your P.R.s for coordination. If you have any questions about this closure or need immediate assistance, contact Donald Brown at x6297 or brownd at jlab.org . 

Allow Time for Shipping & Receiving to Process Packages 
All JSA employees are reminded that Shipping & Receiving must properly log items that have been shipped to the lab before the items can be distributed. This means they must open the package, check the invoice against the purchase order, verify the quantity ordered versus the quantity received, resolve any issues (e.g. shortages, wrong part, incomplete information, inspections required or special handling), log the order receipt into the lab's finance system, and then mark the package for delivery. A notice of delivery by the package carrier is not authorization to interrupt this process, which can potentially introduce errors and delays for everyone. Employees should expect that only work stoppage/critical items may be expedited through this process. While Shipping & Receiving strives to deliver orders to the end user on the day they are received at the laboratory, deliveries are often completed on the next business day. If you have any questions about this notice, contact Christian Whalen at ctwhalen at jlab.org or x5899. 



COMPUTING 
Office 365 Outlook for Email Pilot Users Wanted! 
The IT Division has begun migrating some computer users to the Office 365 Outlook app for email in order to more fully document and test the new email and calendar environment. Over the winter holiday shutdown, all Zimbra users will have their email, calendar, tasks and contacts migrated to Office 365. In the meantime, people who would like to test the Outlook and Outlook Web environment and provide constructive feedback are asked to contact the IT Division by emailing helpdesk at jlab.org . Those testing the environment must be willing to have all email copied to Office 365, but continue to use Zimbra for all calendar activities. If you have any questions or concerns, contact the IT Division Helpdesk, helpdesk at jlab.org or x7155. 


GENERAL ANNOUNCEMENTS 
Introducing ORCID for Research Administrators: What, Why and How? 
Join Jefferson Lab Information Resources personnel for a broadcast of this webinar about ORCIDS on Sept. 11 at 11 a.m. in CEBAF Center Room F224/225. For more information, see the Publications page . 

Publications Refresher Course 
The next Publications Refresher Course will take place Thursday , Sept. 13, at 9:30 in TED Bldg. Room 2559. The course includes a demonstration of how to submit and how to review your publications. Bring any questions you may have about this process. If you plan to attend, R.S.V.P. no later than close of business on Wednesday , Sept. 12, to Kim Edwards . 

Reminder: Register Now for General Wellness Lunch and Learn Offered Sept. 5 
The Human Resources Department will host a “lunch and learn” health and wellness workshop onsite on Wednesday , Sept. 5, noon-1 p.m. A registered dietitian and nutritionist from Optima Health will lead a discussion covering nutrition education, fitness activities, weight loss resources and intervention programs to assist with stress reduction. Space for this free workshop is limited, and registration is required. For more information and a link to the registration page, see the full memo . 

CONTACT 
The JLab Weekly provides information on the status of safety, accelerator operations, experiments, reviews, upcoming activities and special events. Deadline for submission is every Tuesday by 10 a.m. Submit new items to: the Communications Office or contact Kandice Carter at x7263.
