Tornado Season Begins in March
March comes in like a lion and goes out like a lamb, according to the old idiom. While that may be good news for kite aficionados, the many breezy weather fronts that blow through Hampton Roads can bring the threat of tornadoes.

JLab has many weather radios distributed around the site, and these sound an alarm when triggered by a National Weather Service alert. In addition, the JLab Tornado Warning Siren alerts workers who maybe outside. When you hear the alert, go immediately to the nearest severe wind shelter area. These areas are well marked and are generally in the strongest parts of the buildings, away from windows. If you are not sure where the nearest severe wind take shelter areas are in buildings you frequently visit, you can find them on each building evacuation map. If you are stuck outside and cannot safely get to a sturdy structure in the event of imminent severe weather, you can lie down in a low-lying area, such as a ditch. Note that the JLab Tornado Warning Siren is tested the first working Friday of every month at 10:30 a.m.; no response is required for these scheduled functional tests.

Also consider downloading one of the many free weather apps available for your smartphone. These apps can alert you to severe weather in your local area, wherever you roam.


Reserve Your Space in the ARC Library
Users coming to JLab for a stay of short or intermediate duration now have an attractive option for work space: The newly refurbished user space in the ARC building library. This space features 36 work stations with L-shaped tables and comfortable chairs, Ethernet ports and WiFi access. Several work stations have been equipped with Linux computers (providing access to the lab's internal network) and telephones. Lockers are available to securely store personal items and equipment. A virtual tour of this space is available. Reserve a space online before your next visit with your JLab username/password. For help with reservations, contact Lorelei Chopard.

Brown Bag Lunch Workshops with MIS: Thursday, March 7, Noon, CC F113
Have you ever wondered how to send a letter of increase for a requisition? Want to know how to purchase something from the stockroom? Did you miss the E-Commerce training sessions in January? Management and Information Systems staff will host its first monthly brown bag lunch workshop on Thursday, March 7, noon-1 p.m, in CEBAF Center room F113. Each month, 30 minutes of informal training for a small subset of MIS applications will cover topics from simple "how to" examples to less frequently used features of the software. After the first half hour, staffers will open the floor for questions about any MIS application. A few developers will be in attendance, as will a few application owners, so there will be a wealth of knowledge in the room. The first workshop will cover the purchasing applications used at JLab: Requisitions, E-Commerce, Stockroom and Credit Card Log. Bring your lunch and questions and join us! A few light refreshments will be provided. For more information, see the MIS lunch workshops webpage or email Kari Heffner.

C100 Cryomodule Naming Event
All JLab staff and users are invited to celebrate the completion of the cryomodules designed and built for CEBAF’s 12 GeV Upgrade in a cryomodule naming event in the Test Lab Addition High Bay at 11:30 a.m. on Tuesday, March 12. Lab Director Hugh Montgomery and Associate Director of the Accelerator Division Andrew Hutton will recognize the SRF working groups’ contributions to the project and announce the cryomodule-naming contest winners. The SRF working groups and cryomodule-naming contest winners will receive a special commemorative C100 T-shirt. For more information, contact Michelle Lechman.

New Electronic RWP System Now Available
The Radcon Department is working hard toward going green. The department has developed a new electronic system for Radiological Work Permits (RWPs). Customers can start the RWP process by providing basic information about the job, who will be working on the job, etc. Once a customer has completed their portion, Radcon personnel will continue the RWP by adding Radcon-appropriate information and moving the document through the electronic signature process, so that work can begin. If you have questions about the electronic process, you may contact any RadCon staff member.

Come Learn About JLab Publications
Feeling a little rusty on your publications submission skills? Want to learn the ins and outs of the system? Have questions that need desperate answers? Bring your coffee and attend the next JLab Publications Refresher Course at 9 a.m. on Wednesday, March 13, in CEBAF Center room F226. Refreshments will be provided for this one-hour course. Seats are limited, so reserve yours with an R.S.V.P. to Kim Kindrew by 5 p.m., March 12.

Industry Presentation: The Effects of Radiation and Advancement in FPGA Technology for Instrumentation and Control Systems
National Instruments (NI) Representative Brian Reiche will present information related to measurement and control systems. As NI technology is used for increasingly critical applications in high-energy physics, it is important for scientists and engineers to understand the effects of neutron and gamma radiation on the operation of instrumentation and control systems. In addition, recent advancements in field-programmable gate array technology enable scientists and engineers to develop flexible instrumentation and control systems that can be adopted to future performance needs. This talk will show how FPGAs have changed and will keep changing future instrumentation and control systems. This lunchtime talk will be held in CEBAF Center room F224-225 on March 13 at noon. R.S.V.P. to Christiana Grenoble.

Colloquium and Public Lecture: The Origin(s) of the Heavy Elements
The rapid neutron capture process (r-process) is thought to be responsible for the creation of more than half of all elements beyond iron. Yet, the site for the r-process was labeled as one of eleven greatest unanswered questions in physics. Ani Aprahamian, the Freimann Professor of experimental nuclear physics at the University of Notre Dame, will discuss the work to determine the most crucial nuclei to measure using an r-process simulation code based on sensitivities to various basic nuclear properties, such as nuclear masses, beta decay rates, neutron capture cross-sections, and beta-delayed neutron emissions. Results from this research have been used and will be used to determine the experimental programs of radioactive ion beam facilities worldwide. The colloquium is offered in the CEBAF Center auditorium at 4 p.m. on March 13.

Tracking Thomas at JLab
Little Thomas is visiting all corners of the JLab campus. If you can identify his location this week, email Kandice Carter with your guess. Guesses are accepted through Friday.

Keith Harding, Becky Mosbrucker and Marcy Stutzman correctly guessed the location for Feb. 27. Honorable mentions go to Russell Mammei, Harry Fanning and Ron Bartek. Check out the Tracking Thomas webpage for a better view of his last location and this week's new mystery photo.

JLab Weekly Briefs is an ongoing publication providing information on the status of safety, accelerator operations, experiments, free-electron laser, reviews, upcoming activities and special events. Deadline for submission is every Tuesday by 10 a.m. Submit new items to: Public Affairs or contact Kandice Carter at x7263.
