12 GeV Upgrade

At the request of the Office of Nuclear Physics, Daniel Lehman, Director of the Office of Project Assessment in the DOE Office of Science, has convened a team of 18 experts in an Independent Project Review of the 12 GeV Upgrade at JLab on September 22-24. The purpose of the review is to assess all aspects of the project – technical, cost, schedule, management and ES&H – as the project proceeds with construction.


Operations personnel continued to deliver beam to the halls with some issues. On the Sept. 15 swing shift, beam got stuck in the injector again. VFV0L06 was suspected; the valve was jumpered so that it would stay in an open position at all times and not block beam again. Several hours were spent cleaning up the accelerator to lower the Hall A Compton count noise level. There were problems with the paging system; sometimes pages did not go through. There were elevated ep ion chamber trips during the transition of the Hall A fast feedback from ‘on’ to ‘off’ or from ‘off’ to ‘on’. Commissioning of cryomodule 1L04 continued, and four cavities of the zone have been back online since last Wednesday.

Theory Center

Theory Center staff took part in the quadrennial DOE review of theory groups at U.S. National Laboratories last week in Gaithersburg, MD. Presentations were made on achievements over the past four years and plans for future research in areas including hadron spectroscopy (in lattice QCD and the Excited Baryon Analysis Center), three-dimensional hadron structure and few-body physics. The Review will determine the level of funding for the Theory Center for the next four years.

Environment, Safety, Health & Quality

In keeping with the theme of National Preparedness Month, the next step after "Get a Kit" is "Make a Plan." First, find out what kinds of disasters, both natural and man-made, are most likely to occur in your area. Then make sure you have a family emergency plan that addresses each scenario. Talk to your neighbors about how you can work together in the event of an emergency.

You may also want to inquire about emergency plans at places where your family spends time: work, daycare and school. If no plans exist, consider volunteering to help create one.

Also, your family may not be together when disaster strikes, so it is important to plan in advance: how you will contact one another; how you will get back together; and what you will do in different situations.You will be better prepared to safely reunite your family and loved ones during an emergency if you think ahead and communicate with others in advance, using these tips:

  • Identify an out-of town contact. It may be easier to make a long-distance phone call than to call across town, so an out-of-town contact may be in a better position to communicate among separated family members;
  • Be sure every member of your family knows the phone number and has a cell phone, coins or a prepaid phone card to call the emergency contact. If you have a cell phone, program that person(s) as "ICE" (In Case of Emergency) in your phone. If you are in an accident, emergency personnel will often check your ICE listings to contact someone you know. Make sure to tell your family and friends that you’ve listed them as emergency contacts;
  • Teach family members how to use text messaging. Text messages can often get around network disruptions when a phone call might not be able to get through;
  • Subscribe to alert services. Many communities now have systems that will send instant text alerts or e-mails to let you know about bad weather, road closings, local emergencies, etc. Sign up by visiting your local Office of Emergency Management web site.

ES&H Manual Revision Update and New Content
ES&H Manual Chapter 6121 Machine Tools and its associated Appendix T1 Safe Operation of Machine Tools were approved Sept. 21. These documents were re-written to comply with JLab's Work Planning, Control, and Authorization Program developed during 2008. JLab considers machine tools to be inherently risky. It has therefore been determined that use of a machine tool carries an unmitigated Risk Code 3. An Operational Safety Procedure (OSP) is now required to cover each machine tool and to be read by machine operators to ensure compliance with training and authorization requirements. This manual content will become effective Jan. 1, 2010. Ned Walker, Industrial Safety Professional ( or x6638), is the Author of Record and is available to assist managers, owners and operators of machine tools to achieve compliance with this chapter.


APS April Meeting Abstract Submission Deadline is Oct. 23
The 2010 APS April Meeting will take place at the Marriott Wardman Park Hotel in Washington, DC. Because the April Meeting will be held in conjunction with the annual winter meeting of the American Association of Physics Teachers (AAPT), it has been moved to February. The deadline for receipt of abstracts is Friday, Oct. 23, at 5 p.m. EDT (2 p.m. PDT).

SRF Colloquium Set for Oct. 1
A special colloquium, High-Field Losses in SRF Cavities, will be presented by Gianluigi Ciovati of the Accelerator Division SRF Institute and recipient of the Presidential Early Career Award for Scientists and Engineers on Thursday, Oct. 1 from 3:30 to 4:30 p.m. in the CEBAF Center auditorium.
