Hall D: First Result from Upgraded CEBAF Opens Door to Exploring the Universal Glue
The first experimental result has been published from the newly upgraded CEBAF at Jefferson Lab. The result demonstrates the feasibility of the GlueX experiment, which is designed to study quark confinement: why no quark has ever been found alone. Read more here.

Remember to submit your papers for approval to the Jefferson Lab Publications database.

JSA Young Scientist Program Now Accepting Applications
The JSA Promising Young Scientist program is accepting applications for the 2017-2018 academic year. The program, which is funded by the JSA Initiatives Fund, will assist candidates to prepare for faculty interviews by traveling to a host institution to present a talk and participate in a mock interview. The candidates will also have an opportunity to teach a class session. The application deadline is 5 p.m. on Friday, May 12. For more information, see the full announcement.

DOE Office of Science Graduate Student Research Program Is Accepting Applications
The goal of the Office of Science Graduate Student Research program is to prepare graduate students for science, technology, engineering or mathematics careers critically important to the DOE Office of Science mission. The program provides supplemental funds for graduate awardees to conduct part of their thesis research at a host DOE laboratory in collaboration with a DOE laboratory scientist within a defined award period, typically three months-one year. The application deadline is 5 p.m. on Tuesday, May 16.
Photo Trivia for Records and Information Management Month

The final winner of our Raiders of the Lost Archives photo identification project is Jodi Patient. Thanks to the Jefferson Lab community for helping archives staff identify people, objects and places during Records and Information Management (RIM) Month. Feel free to review the confirmed and best guess answers with the photos here. Visit to view a new photo every week!

Center for Theoretical and Computational Physics

A new paper shows that beam asymmetries in η and η' photoproduction are sensitive to hidden strangeness components, and estimates the contribution of φ exchange, which is expected to be the dominant hidden strangeness contribution. The ratio of the asymmetries is predicted to be close to unity in the forward region.

Environment, Safety, Health and Quality

Free Health Screenings Offered by Optima Health
Optima Health is offering free and confidential health screenings at Jefferson Lab on May 31. The 10-minute screenings will take place in CEBAF Center room F113. At this screening, you will learn more about blood pressure, cholesterol, diabetes risk, Body Mass Index, tobacco cessation, and the benefits of regular physical activity. This free service is open to Jefferson Lab employees as well as Users and subcontractors. Walk-ins are welcome, but an appointment is appreciated. The deadline for making an appointment for this free service is Thursday, May 22. To schedule an appointment, contact Occupational Medicine with your preferred appointment times (9 a.m.-1p.m.) at,, or x7539.

Computing and Networking Infrastructure

Reminder: 2017 Jefferson Lab IT Survey
The Jefferson Lab IT Division has developed a survey to learn about the lab's usage of IT resources and the support that division staff members are providing. The survey was emailed to all members of the lab community on May 2. The email contains your unique link to the survey. A final reminder will be emailed to anyone who has not completed the survey prior to the closing date. If you have any questions or concerns regarding this survey, contact Rachel Harris at


Site-Wide Alert Text Messages Will Now Come from 215 Area Code
The IT Division’s Telecom group recently obtained a new texting service from Verizon. Using this service will allow Telecom to send text messages to mobile phones without needing to know the service provider of the recipient. While much of this change will be invisible to text message recipients, the messages will now come from phone number (215) 970-0778, and the message will be prefixed with "JLAB:". Previously, most people received the texts from "" or "”. The new service will be tested on Friday morning when the monthly Tornado Siren Test notification is sent out.

Reminder: Contact Staff Services for Work Events Requiring Food Service
If you require food and/or beverage service for any work-related event, contact Staff Services at as early as possible in your event-planning process. Jefferson Lab has a contractual obligation with the new food service subcontractor, eLITE Management Group, that gives the subcontractor exclusive rights to provide catering service on-site. This is the same requirement that the lab had in place with the previous subcontractor. Staff Services can provide specific guidance on the wide range of options available and order your selections for your conference, meeting or workshop.

New SOTR Training Offered on Friday, May 5
A Jefferson Lab training session for new Subcontracting Officer Technical Representatives (GEN020) will take place on Friday, May 5, 8 a.m.-12 noon in Room 53 of the Support Service Center. Participants can register by COB on Thursday in Jefferson Lab's Learning Management System. For more information and a link, see the full memo.

Rhyme Time: Submit Silly Verse About Your Work for Limerick Day!
Jefferson Lab is celebrating National Limerick Day on May 12 by publishing limericks relating to our science and technologies or life at the lab. The best limericks submitted by the Jefferson Lab community will be posted to social media with attributions to the authors. The top employee limerick will receive a $50 employee recognition award. If you would like to participate, email your name, job title and home division with your entry to by COB Tuesday, May 9. Multiple entries are allowed and anonymous entries (not eligible for prize) may be left in the slot at CEBAF Center room C226. For inspiration and examples of popular limericks, see the Web Exhibits website.

Run-A-Round Set for May 17: Registration Underway
The 32nd Annual Jefferson Lab Run-A-Round will be held 3-6 p.m. on Wednesday, May 17. The event begins in front of CEBAF Center at 3 p.m. with the debut of the 2017 Jefferson Lab T-shirt. Lab staff, Users, students, full-time contractors and immediate family members are invited to participate. Participating staff and Users will receive a free 2017 JLab T-shirt. Food, beverages, music and awards will follow the race. To be eligible for awards, runners and walkers must register online before 5 p.m. on Tuesday, May 16.
