12 GeV Upgrade

The Hall B CLAS12 Torus magnet vacuum jacket is being pumped down in preparation for cooling and power tests. As expected during magnet commissioning, minor leaks are being found and repairs completed. Last week, Hall C saw its first beam in many years. The low energy, pulsed beam was used to check out the new beamline into Hall C, which will help the future beam commissioning of the Super High Momentum Spectrometer by identifying any issues well in advance.

JSA Announces Graduate Fellows and Sabbatical Leave Support
Jefferson Sciences Associates, LLC, has announced the award of eight JSA/Jefferson Lab graduate fellowships for 2016-2017. The doctoral students will use the fellowships to support their advanced studies at their universities and conduct research at Jefferson Lab. The program is supported by the JSA Initiatives Fund, and each $12,000 fellowship award contributes to the student’s research assistant stipend and is supplemented by support from the home institution. See the announcement for the full list of graduate fellows. JSA also awarded support to University of South Carolina Professor Ralf Gothe for his sabbatical leave at Jefferson Lab in 2017.

American Physical Society Dissertation Award in Nuclear Physics Call for Nominations
The award consists of $2,500 and an allowance for travel to the annual Spring Meeting of the Division of Nuclear Physics of the American Physical Society, at which the award will be presented. Nominations are open to any person who has received a Ph.D. degree in experimental or theoretical nuclear physics from a North American university within the two-year period preceding July 1, 2016. Nominations are due by July 1. Nomination information is available on the APS website.

Center for Theoretical and Computational Physics

Chiral effective field theory (chiEFT) provides a description of low-energy nuclear dynamics in terms of nucleons and pions, consistent with the symmetries of QCD. A new paper carries out the first chiEFT calculation of tritium β-decay, including loop corrections in the charge-changing nuclear weak current. The corrections originating from multi-pion exchanges are found to be as large as those from one-pion exchange.

Inventory of Personal Property Begins Soon
The annual physical inventory of personal property will start June 6. It’s recommended that all Jefferson Lab Property Custodians, which includes anyone who is assigned Jefferson Lab property, to be prepared to make items available for this process and to excess any items that the custodian no longer needs for business purposes.

If you have items on your property list that you no longer need, you may excess these items via the website. Simply click on the tag number for the item, and then click the "Relocate/Transfer/Excess this item" button. You can access your property list via the search function here.

If you would like to excess any other items that are not on your property list and do not have a numbered (F123456) property tag -- such as desks, chairs, old trailers, carts, spools, etc. -- you may do so using the link.

Property Custodians are reminded that you may not dispose of items in the Central Material Storage Area without first communicating with Property Management. If you need assistance, contact Danielle Tarver, x7025, or Tim Wagner, x7348.

Items in good condition that are excessed via the processes above are being made available for re-use by Property Management for Jefferson Lab Property Custodians. These items are available only for use on-site for Jefferson Lab business purposes and are still Government Property.

Environment, Health, Safety and Quality

The Green Electronics Council (GEC) has announced that Jefferson Lab is a winner of the 2016 EPEAT Sustainable Purchasing Award, which recognizes excellence in the procurement of sustainable electronics. The 38 winners of the 2016 awards were recognized for their procurement efforts in up to three categories: PCs and Displays, Imaging Equipment and Televisions. The award winners represented a wide range of organizations, including national and provincial/state governments, leading academic institutions and the healthcare sector.

“Organizations have a choice when purchasing electronics. They can either seek to reduce their environmental impacts through their purchasing decisions or not. We congratulate the 2016 EPEAT Sustainable Purchasing Award winners for making the right choice,” said Nancy Gillis, CEO of the Green Electronics Council.

Thoughtful procurement is a cornerstone of Jefferson Lab's Environmental Management System, and special recognition goes out to the procurement staff for this and similar efforts.
