12 GeV Upgrade

At the request of DOE's Office of Nuclear Physics, Stephen Meador, Director of the Office of Project Assessment in DOE's Office of Science, convened a team of 17 experts and seven observers in an Independent Project Review of the 12 GeV CEBAF Upgrade Project at Jefferson Lab, Nov. 18-20. The purpose of the review was to assess all aspects of the project, including technical, cost, schedule, management and ES&H. The review team provided valuable feedback in all areas, and a total of nine recommendations were given in the Close-out Report. The committee congratulated the 12 GeV Team on the early completion of accelerator commissioning and the successful start of commissioning of the Hall D systems. The committee also highlighted the significant progress made on the superconducting magnets, as well as the project’s safety record and completion of four Accelerator Readiness Reviews. .

Center for Theoretical and Computational Physics

Processes studied with CLAS, like γp to K+K-p, include strange baryon resonances that decay to K-p, and meson states that decay to K+K-. Mesons and baryons are interlinked. Making cuts to isolate one or the other information on this interlinking is lost. A step towards understanding the overlap of baryon and meson interactions, a model called B5, is studied in a new paper from the JPAC (Joint Physics Analysis Center). Further steps underway will allow a more complete picture of the dynamics of all such multiparticle reactions.

Personal Work Planning Event
Recently, a Jefferson Lab worker related that during his recovery from a bicycle accident, he had time to reflect on how he could have used the lab's work planning process to avoid his event. He was riding at a good speed while on a new route, turned to make a wide turn but was thinking of issues at work and not focused on the ride. He hit some wet leaves in the turn and crashed and slid many feet. He avoided a  more serious injury by wearing a helmet.

While at home, nursing bruises, aches and pains, he thought about how he could have avoided his predicament. It dawned on him that if he had:

  1.  Stopped to think about a change in the activity - i.e. change of route, he may have recognized a different turn;
  2. Reconsidered a change of conditions that affected the turn i.e. wet leaves, which are notorious slipping hazards, even for cars; and
  3. Wasn't distracted by thinking of work and focused on the road and conditions, he may have slowed down or recognized the changing conditions.

With the holidays coming, we all need to be aware of the same conditions that are part of work planning: 

  • Changing environments - wet, ice, amount and type of lighting, type of footwear, etc;
  • Distractions from the task at hand;
  • Last-minute change in plans for which we are not properly prepared to handle; and
  • Having the correct emergency supplies for traveling in adverse weather we may not encounter very often.
If we take just a few seconds to stop and think, many hazards can be avoided, and we all can have a safe and wonderful holiday.

Computing and Networking Infrastructure

Zimbra Email and Calendar Upgrade
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.

Announcements

Tornado Warning Siren Test Set for Friday, Dec. 5

Jefferson Lab's tornado warning siren will undergo its monthly operational test at 10:30 a.m. on Friday, Dec. 5. Don't respond to the siren; this is a test of the siren system and not a personnel response exercise. Individuals planning to be in the Central Materials Storage Area (where the siren is located) while the test is taking place must have with them and wear two layers of hearing protection.

2015 General Access RWP Ready for Review
The 2015 General Access Radiological Work Permit is now available for signature. If you are a radiation worker at Jefferson Lab, you must read and electronically sign the new RWP before Dec. 31 to retain your accelerator site access. This year’s RWP contains new restrictions/policies. Be sure to read this document in its entirety. You may access this document from off-site. The document can be found here. If you have trouble with the links or with signing the document, contact Becky Mosbrucker at becky@jlab.org or 757-269-7236. If you have any other questions regarding this permit, contact the Radiation Control Department at 876-1743.

Colloquium: Energy Critical Elements: More Precious than Gold
Elements that were once laboratory curiosities, like neodymium, tellurium, and terbium, now figure centrally when novel energy systems are discussed. Many of these elements are not at present mined, refined, or traded in large quantities. New technologies can only impact our energy needs, however, if they can be scaled from laboratory, to demonstration, to massive implementation. As a result, some previously unfamiliar elements will be needed in great quantities. Although every element has its unique story, these Energy Critical Elements have many features in common. Robert Jaffe, Massachusetts Institute of Technology, will describe the shared characteristics of these elements, their roles in emerging technologies, potential constraints on their availability, and government actions that can help avoid disruptive shortages. As an example, he will focus especially on elements that are required for photovoltaic technologies. The talk will take place on Wednesday, Dec. 10 at 3 p.m. in the CEBAF Center auditorium.

Hotel Cancellation Policy Changes
The Hilton and Marriott Hotel chains are revising their cancellation policy. Starting Jan. 1, 2015, these chains will charge a penalty, equivalent to one nights’ lodging, for reservations that are not canceled the day before the scheduled arrival. This policy is stiffer than previous policy, which generally required cancellation by 4 p.m. on the day of scheduled arrival. Contact Jefferson Lab’s subcontract travel agency, CI Travel, 757-461-0022, or your travel administrator whenever travel plans change. When a hotel has been reserved through CI Travel, the agency may have leverage to get the penalty waived.

TIAA-CREF 401(k) GSRA Open Enrollment is Underway

Freestock Item Reduction and Stored Property Review
Next week, Freestock items will be significantly reduced. The last chance to review and select items before they are processed for donation or disposal is this week. Stop by the Stockroom, located in room 108 in the Experimental Equipment Lab (Bldg. 90), to check out the items. Do not drop off any items without approval from Stockroom personnel. For assistance with Freestock, contact Lawrence Ferbee (x6297), Angela Stanley or Christian Whalen.

Property items may only be stored for one year, and then stored items must be reviewed per the "Equipment Held For Future Projects" guidance in the Property Manual. Property items being stored as "Spares" also must be reviewed for their relevance and condition needed for current operations. Once you review your stored and spare items and determine that continued storage is necessary, you may fill out and submit the renewal forms online. For assistance with this process, contact Christian Whalen, x5899.
