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 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:
