12 GeV Upgrade

The tunnel air conditioning contract was awarded to Warwick Plumbing & Heating on Nov. 12. This is the same contractor performing the work for the North and South Access Buildings’ backup cooling towers. Warwick is completing Jefferson Lab training and administrative submittals to be ready to start on-site work in the accelerator tunnel on Dec. 22. Warwick will be working through the holiday shutdown to maximize the work done in the tunnel during this scheduled accelerator down (SAD) until Jan. 28, 2015. The remaining tunnel work will be completed during the Summer 2015 SAD.

Physics

Jefferson Lab Published Journal Articles Dec. 8-12
Remember to submit your papers for approval to the Jefferson Lab Publications database.

Center for Theoretical and Computational Physics

Quantum Monte Carlo methods have proved very valuable in the study of the structure and reactions of light nuclei and nucleonic matter starting from realistic nuclear interactions and currents. A new paper presents a variety of results for a number of observables, including the low-lying spectra of light nuclei, form factors, transition matrix elements, electroweak response functions relevant in electron and neutrino scattering, and the properties of dense nucleonic matter in neutron stars. A coherent picture of nuclear structure and dynamics emerges.

Beware of Holiday Carjacking Scams
The U.S. Army Criminal Investigation Command is warning service members about a new carjacking scam targeting unsuspecting holiday shoppers. Criminals will place a $100 bill on an individual's windshield under the wiper blade; while the victim is distracted and gets out to retrieve the cash, the criminals approach the vehicle and rob the victim of their belongings and car. Should anyone discover money on their vehicle, they should quickly move to a safe, public location and notify law enforcement or security personnel immediately. Lock your doors, and do not get out of the vehicle to retrieve the bill. More information and parking lot safety tips can be found here.

Computing and Networking Infrastructure

SeeVogh To Be Discontinued on Jan. 1, 2015
SeeVogh videoconferencing services at Jefferson Lab will not be renewed in January 2015. BlueJeans is the lab's current video teleconferencing solution. Since the lab started using BlueJeans, the use of SeeVogh has steadily dropped, and there has been no SeeVogh usage since September 2014. For information on BlueJeans, visit https://cc.jlab.org/bluejeans. If you have any questions or concerns regarding the discontinuation of SeeVogh at Jefferson Lab, contact the IT Division Helpdesk at x7155.

The Zimbra email and calendar system will be upgraded on Jan. 2, 2015. During the upgrade, there will be intermittent outages as systems are upgraded and rebooted. Current plans are to start the upgrade at around 8 a.m. All email should be back up and stable by 8 p.m. If you have any questions or concerns regarding this upgrade, contact the IT Division Helpdesk at helpdesk@jlab.org or x7155.
