12 GeV Upgrade

The summer Scheduled Accelerator Down (SAD) is in full swing, with maintenance activities ongoing in the accelerator areas and across the site. In Hall C, the Super High Momentum Spectrometer shielding work is complete. Hall D is being readied to start the commissioning activities at the completion of the SAD. In the Hall B Torus Cryostat factory, assembly is progressing in preparation for the arrival of magnet coils later this year. In an effort to mitigate potential ergonomic concerns due to static or awkward body positioning during some of the assembly steps, modifications have been made to the set-up and tooling.

Physics

Jefferson Lab Published Journal Articles, June 2-6

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

Center for Theoretical and Computational Physics

A new approach to transverse momentum dependence in hard processes is described in a recent Theory Center paper. The paper introduces distributions of quarks in virtuality and relates these with distributions in transverse momentum. The approach allows one to generate hard momentum "tails" from models of "soft" distributions at small momenta.

Facilities Management and Logistics

Roadwork to Temporarily Close Section of Lawrence Drive
The construction work taking place next door at the Tech Center at Oyster Point is progressing. While the construction so far has had little impact on drivers, the contractor's next task will halt traffic on Lawrence Drive. Soon, the developer will begin installing the first few sections of sewer pipe for the development. These sections will run under Lawrence Drive, requiring the temporary closure of Lawrence Drive at Hogan Drive. Vehicles will not be able to access Lawrence Drive from Hogan Drive during this period. Road closure signs will be posted to prevent vehicles from using the affected section of Lawrence Drive.

A map of the affected area is available via the web posting of this announcement.

The closure is scheduled to start Thursday morning, June 12, and continue throughout the weekend (weather permitting). When entering or leaving the lab via Hogan Drive during the closure period, plan to use the entrances at either Hofstadter Road or Rattley Road. If you have any questions or concerns about this work, contact Bob Sperlazza at x6241.

Part of Lawrence Drive to Become One-Way Only
Jefferson Lab and the School Bus Depot will be sharing the Hogan Drive entrance with the new Tech Center at Oyster Point Market Place development that is currently being constructed between Hogan Drive and Oyster Point Road. To accommodate this additional traffic on Hogan Drive, the developer is going to add a new entry and exit turn lane, as well as a road divider on Hogan Drive. These changes make it necessary to convert the north end of Lawrence Drive to a one-way street.

The one-way street will start at the intersection of Lawrence Drive and Hofstadter Road and will continue to Hogan Drive. Those traveling north on Lawrence Drive will be required to turn onto Hofstadter Road to exit the lab. The use of Hofstadter Road will also be required when leaving the Applied Research Center and Support Services Center parking lots if you wish to exit the lab using Hogan Drive.

The one-way conversion of Lawrence Drive will occur on June 15. Awareness signs will be posted around the affected area to provide proper notification of the change.

 

Environment, Safety, Health and Quality

U.S. Highway Deaths Increased in 2012
Here's an update on the safety of America's roadways. The National Highway Traffic Safety Administration confirmed that U.S. highway deaths rose by four percent in 2012 from the previous year, as the agency released the 2012 Fatality Analysis Reporting System (FARS) data. Most deaths involved motorcyclists and pedestrians, and highway deaths took for more than 30,000 lives each year. Fatalities among pedestrians increased 6.4 percent, motorcyclist fatalities increased 7.1 percent, and deaths in crashes involving drunk drivers rose 4.6 percent, with most of those crashes involving drivers with a blood alcohol concentration of  0.15 or higher. In Virginia, the number of deaths due to drunk drivers decreased.

Computing and Networking Infrastructure

Training Offered for New Spam and Virus Filter Software
On June 17, the CNI group will migrate from the current spam and virus solutions to an updated environment. This environment is expected to provide better spam- and virus-blocking capabilities, while also providing a local (at Jefferson Lab) User Spam Quarantine server. A training session will be held in the CEBAF Center auditorium at 2 p.m. on Thursday, June 12. This training will provide information on how to manage your individual message quarantine. If you have any questions or concerns, contact the IT Division Helpdesk or x7155.

ReadyTalk End-of-Life
ReadyTalk is an audio, video and web conferencing service that was offered by ESnet Collaboration Services (ECS) and will be discontinued by the lab's provider on Sept. 30. With the purchase of BlueJeans, the IT Division has decided to make BlueJeans the primary option for audio and video conferencing. Like ReadyTalk, BlueJeans provides audio conferencing, H.323 video conferencing and web conferencing. Jefferson Lab will end support for ReadyTalk by Aug. 1.

To assist with an easy migration, there will be training sessions held on June 25, July 10, and July 23 at 2 p.m. in CEBAF Center room F113. ReadyTalk was mainly used for audio conferencing, therefore, audio conferencing will be the focus of these training sessions. There will be time at the end of each session for all questions regarding BlueJeans (H.323, web conferencing, etc.). To learn more, visit the BlueJeans webpage for information on logging in and configuring BlueJeans with your Jefferson Lab computer account.

CNI Maintenance Period Set for Tuesday, June 17, 5-10 p.m.
CNI is planning a maintenance period on Tuesday, June 17, 5-10 p.m. During this time, there will be an incoming mail outage while the lab shifts over to the new spam and virus filter software. All incoming mail will be stored and will be delivered once the cutover is complete. Incoming mail will start flowing again no later than 10 p.m. No email will be lost during this transition.

There will be brief network outages in the following buildings due to switch code upgrades: Test Lab (Bldg. 58), Technology and Engineering Development Building (Bldg. 55), the Free-Electron Laser (Bldg. 18), the Experimental Equipment Lab (Bldg. 90), CEBAF Center (Bldg. 12), the Support Service Center (Bldg. 28), the Radcon Complex (Bldgs. 52, 52b, 52c), the Applied Research Center, Building 19, Building 89, Building 200, Building 201, Building 34A, Building 98 and Building 96B. Not all switches within each major building will be affected, so many devices and phones will stay connected. Individual outages will last no longer than 10 minutes.

There will also be short phone outages in the ARC, SSC, Building 19, CEBAF Center, Test Lab, EEL and Building 57 to update the phone routing. Each outage will last no more than 15 minutes.

Finally, patches will be released to all Linux and Windows desktops. Plan on rebooting your desktop system on either Wednesday or Thursday to finalize the patch installation. If you have any questions or concerns about these maintenance activities, please contact the IT Division Helpdesk at helpdesk@jlab.org, or x7155.
