12 GeV Upgrade

The first part of the Dipole magnet for the Super High Momentum Spectrometer (SHMS) was delivered to Hall C early in June. The CCR, or Cryogenic Control Reservoir, was fabricated in Illinois but has spent recent years in France, where it has been customized for the dipole by the magnet company, Sigmaphi. This vendor continues to work on sealing and leak-testing all three of the magnets they are building for Jefferson Lab. In Hall C, handrails have been installed on the concrete block that will become the roof of the SHMS shield house, and the vacuum connection between the first two SHMS magnets has been completed. Installation of the permanent cryogenic gas lines on the new spectrometer continues.

Publications Training and Refresher Course
Did you know that Jefferson Lab must submit the final, peer reviewed, accepted manuscripts to the Department of Energy? See the link for information on how to do this or come to the next Publications Training and Refresher course on Thursday, July 14, at 2 p.m. in CEBAF Center room F224-225. In this session, authors will learn how to submit manuscripts to the Publications Review and Approval System, how to make recommended revisions to papers during the signature process, and how to add the relevant information once the paper is published. If you plan to attend, contact Kim Edwards at kindrew@jlab.org by Wednesday, July 13.

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

During the last quarter century, chiral effective field theory has been widely used for the derivation of nuclear forces and electroweak currents. Such a theory provides the most general scheme accommodating all possible interactions among nucleons, Δ isobars and pions compatible with the relevant symmetries — in particular, chiral symmetry — of low-energy quantum chromodynamics, the underlying theory of strong interactions. A new paper describes the construction of classes of chiral two-nucleon potentials, which are local in configuration space and are therefore suitable for use, in particular, with quantum Monte Carlo methods. These are applied to a calculation of binding energies of nuclei with mass numbers A = 3, 4 and 6.

Facilities Management and Logistics

Lab Annual Electricity Consumption Reduction Test Set for June 23
Jefferson Lab is again participating in the interruptible electrical load program. This demand-side energy management helps to ensure that periods of tight electricity supply on the grid don't turn into brown outs or power outages. To qualify for the program, the lab must participate in the annual test, which will take place the afternoon of Thursday, June 23. Those individuals/groups using systems that are electrically power intensive, such as DC power supplies, operations in the Test Lab VTA (vertical test area) or cavity test areas, should schedule their operations such that these operations do not occur during the 1:45-3:15 p.m. test period on June 23.

Jefferson Lab Roads Update: Rattley Rd. Closure
During the week of July 11, the contractor will start the rebuilding of Rattley Rd. More information about road closings will be posted as it becomes available.
 

Environment, Health, Safety and Quality

Portable Generator Safety
Summer has arrived, along with hurricane season, higher temperatures and severe evening thunderstorms, all of which can cause an electrical utility outage. Portable generators can be a good source of temporary power during electrical outages; but, if used improperly, generators also can prove to be dangerous. Here are some simple precautions that you can take to keep you and others safe from the dangers of electric shock and carbon monoxide poisoning resulting from improper use of a portable generator:
  • Do not connect the generator directly to the house wiring (use an approved transfer switch);
  • Use Ground Fault Circuit Interrupters (GFCIs) with the generator if they are not already built in;
  • Make sure extension cords have no damage and are of a sufficient size for the load to be powered;
  • Do not use the generator inside your home/garage - operate it in a well-ventilated area outdoors away from windows, doors, and vents;
  • Make sure your home has a working carbon monoxide alarm; and
  • Always turn the generator off and allow it to cool down before fueling.
As always, follow the manufacturer guidelines for setup and operation. It is also strongly recommended to have a licensed electrician install your home generator.

Announcements

Test of Telephone Public Address System Set for Today
Today, Emergency Management Team staff will conduct the monthly test of Jefferson Lab’s Public Address (PA) System, the live audible announcement feature through the lab’s Cisco phones. This monthly operational test of the system occurs at 5:30 p.m. on the third or fourth Wednesday of each month. No actions are required or expected from members of the lab community with this test. Reminder: Active calls are automatically put on “hold.” As soon as the announcement has ended, a call may be re-activated by taking the call off of “hold.” For more information, see the full memo.

Radiation Worker II Class Offered July 12
The Radiation Control Department will hold a Radiation Worker II class on Tuesday, July 12, 9 a.m.-noon in Applied Research Center room 231. This course is required for anyone needing to work in Contamination Areas. Interested individuals must already be Radiation Worker I qualified to sign up for this course. Registration deadline for this course is Friday, July 8. To sign up, contact Maya Keller at mkeller@jlab.org.

Run-A-Round 2016 T-shirts Offered for Sale 
The 2016 Jefferson Lab T-shirts and remaining special-order items are now available for purchase at the CEBAF Center reception desk during normal business hours (8 a.m.- 5 p.m. Monday-Friday). Supplies are limited; first come, first served. Payment may be made in cash or checks (payable to JSA or Jefferson Lab). Prices are posted at the reception desk. The price for the regular adult, short-sleeve T-shirt is $8 (for all available sizes).

JSA Initiatives Fund Program Is Accepting Proposals
JSA is soliciting proposals for Initiatives Fund support for the FY17 program. Members of the Jefferson Lab user community, Jefferson Lab researchers and staff, other individuals or groups who can make unique contributions to the lab's research, development, education and technology transfer missions. The Initiatives Fund is provided by the JSA owners, SURA and PAE Applied Technologies. Proposals are due August 8. For full application information and details, see the full announcement.
