The 2013 JLab User's Group Annual Meeting will take place on May 29-31. The program includes a variety of physics talks, presentations from the Users Group Board, laboratory management and funding agencies, and talks from the new APS fellows and prize winners. Register now online.
Annual Meeting Registration Is Free for Students
The Jefferson Science Associates Initiatives Fund has again sponsored waiving student registration fees. There will be special lunch discussions for graduate students, and free food will be available. The poster competition continues, with a first prize of $1000, a second prize of $500, and a third prize of $250. Poster competition abstracts must be emailed to Lorelei Chopard by Friday, May 17. For more information, contact Natalie Walford.
The FEL team is still operating with only minor activities on optics and beam transport while awaiting funding.
Center for Theoretical and Computational Physics
A new paper shows calculations of the effects of final state interactions on deuteron electro-disintegration using nucleon-nucleon amplitudes derived from George Washington University's SAID analysis and a new parameterization using a Regge model. The two approaches are compared in the region of overlap, with good agreement found between the models. The paper further notes observables, which can provide additional insight due to model sensitivity.
Computing and Networking Infrastructure
CNI Maintenance Period Set for April 16, 5-10 p.m.
The CNI group is planning a maintenance period on Tuesday, April 16. During this time, the Zimbra calendar and email system will be down for an upgrade (see separate announcement for more detailed info). There will be an internet outage 5:30-6:30 p.m. During the outage, computer users will not be able to reach servers outside of JLab. The scratch file server will be down for about 15 minutes for patch installation and for a configuration update; it will be back up no later than 6 p.m. Updated Firefox and Thunderbird packages (17.0.5ESR) will be delivered to fix security issues, and Windows and Linux patches will also be delivered. Plan on rebooting your systems on the Wednesday or Thursday following maintenance to allow installation of these patches to be completed. If you have any questions or concerns regarding the maintenance period, contact the IT Helpdesk, x7155.
Sprint Texting and Direct Connect Training Session
Do you have questions about Sprint texting or direct connect services? A representative from Sprint will be onsite Thursday, April 11, from 10 a.m. until noon in CEBAF Center room F113 to answer questions, offer training and troubleshoot device problems. You will not need to attend the entire session for these services.
Zimbra Calendar and Email Upgrade
On the evening of April 16, the Zimbra email and calendar system will be upgraded. The entire system will be down 5:30-9 p.m. for the upgrade. Email and calendar access will be back up no later than 9 p.m. Email delivered during the upgrade will be stored on the mail servers and will be delivered once Zimbra is back online. If you have any questions or concerns, contact the IT Division Helpdesk, x7155.

Onsite Driving Courtesy
Most JLab vehicle operators are considerate drivers, but sometimes people forget to observe common driver courtesies once they are onsite. All Virginia traffic laws apply onsite and in parking lots. Remember to follow these laws onsite:
- Signal all turns - A number of drivers of both motor vehicles and golf carts have been observed not signaling turns or turning into oncoming traffic.
- Clear the windshield when needed - With temperature differences overnight, golf carts parked outside often have dew-covered windshields that are not being cleaned off before driving.
- Obey all traffic signs and markings - Some drivers have been ignoring the painted stop bars in parking lots and stop signs at intersections by driving over markers without pause or looking for oncoming traffic or by rolling through intersections without first coming to a stop. These markings are for everyone's safety, as they indicate which vehicles have the right of way in parking lots and on JLab roads.
Medical Procedure Documentation & Dosimeter Usage Reminder
Just a reminder from the Radcon Office: If you are a radiation worker/have a current OSL dosimeter and you will be undergoing a medical procedure where you will be injected with a radionuclide, you are encouraged to notify Radiation Control, Becky Mosbrucker, x7236. You should avoid wearing your dosimeter until RadCon clears you for dosimeter use. When you report to RadCon after such a procedure, they will request information about the type of material you were administered, and staff may ask to directly monitor you as a followup for a few days. The purpose of this additional monitoring is to ensure that your JLab occupational exposure record is accurate. The monitoring also helps RadCon assess potential exposure to nearby stored dosimeters or coworkers.
Red Cross Blood Drive Set for April 16
The next American Red Cross Blood Drive is scheduled for Tuesday, April 16, 10 a.m.-4 p.m. in CEBAF Center, Room F113. New and repeat donors are encouraged to attend. Appointments and walk-ins are welcome. All who donate will be entered into a Red Cross drawing to win a $1000 Amex gift card. To schedule an appointment, contact Johnie Banks, x7539. The linked page lists all eligibility requirements.
Education Seeks Projects for Summer Honors Interns
Seven outstanding high school students have been selected to participate in the lab's High School Summer Honors Program, which will be held at the lab June 24-August 2. The students are currently high school juniors and seniors and have expressed interest in pursuing scientific and technical careers. Lab scientists, engineers and other technical managers who are interested in serving as a mentor to high-achieving high school students and have a project, or number of projects, to be accomplished this summer, are asked to send a description of the work to be assigned or any questions you may have about the program to Brita Hampton by May 1. The students will be required to develop a poster about their project and present it during a poster session.
JLab Tornado Drill Survey Results
On March 12, many members of the JLab community participated in the annual statewide Tornado Drill. Afterward, drill participants were asked to complete a short Tornado Preparedness and Response Awareness Survey. Thanks to the 94 non-supervisors and 36 supervisors of the Jefferson Lab community who completed the survey; the results are posted online.
JLab Celebrates National Library Week: April 15-19
Visit the library during national library week and enter your name into a daily drawing to win a Starbucks gift card! Celebrate with library staff through events scheduled all week. See the full announcement.
JLab Records and Information Management Fact of the Week
According to the National Archives and Records Administration, organizational charts are graphic illustrations providing a detailed description of the arrangement and administrative structure of the functional units of an agency. Organizational charts are considered permanent records. Do you have any old org charts? If so, contact Kim Kindrew.
RIM Trivia Question of the Week: Paper is an example of a "medium" for recorded information, as are flash drives, CDs and tapes. The earliest known form of writing is cuneiform, dating back to the 30th century BC. Upon what medium was cuneiform written? The first correct response received at email@example.com wins a Starbucks gift card! (Winner will be notified no later than 5 p.m. Friday following publication of Weekly Briefs. Limit one gift card win per person.)
Congratulations to Samika Hawkins for her speedy correct response to last week's question: I am an important part of managing paper records. I get my name from a type of fiber that comes from abaca, a relative of the banana plant. What am I? Response: Manila Folder
