12 GeV Upgrade

One of the superconducting magnets built in France for the Hall C Super High Momentum Spectrometer (SHMS) is now crossing the North Atlantic by ship and is expected to arrive in Norfolk by the end of September. This "Q2" magnet will be delivered to Jefferson Lab, outfitted with survey marks, and placed on the SHMS carriage for connection to the cryogenic, power and controls systems.

The leak that was discovered in the dipole magnet helium system in July has now been repaired. The dipole was cut open to access the faulty component, and it has since been welded closed. The magnet is being crated for shipment to the U.S. now.

The last magnet, Q3, is in the final assembly phase. More work has taken place in Hall C and the Experimental Staging Building to verify the performance of the new detectors.  One of the SHMS drift chambers is already mounted on the frame which will support it in the SHMS.

Positron Working Group Forms at Jefferson Lab
A newly created Positron Working Group (PWG) has been established to explore the physics possibilities of a positron experimental program at Jefferson Lab. The inaugural goal of the PWG is to investigate the capabilities, requirements and physics reach with respect to positron research topics and then deliver a Jefferson Lab Positron Physics White Paper in 2017. If you would like to participate in the process, subscribe to the PWG mailing list by sending an email to with the word “subscribe” in the subject field.

Environment, Safety, Health and Quality

Personal Protective Equipment Can Minimize Exposure to Hazards
Jefferson Lab's ES&H Manual Chapter 6620 Personal Protective Equipment (PPE) Program provides guidance to minimize employee exposure to hazards, such as cutting, grinding, drilling, sharp edges, pinch and temperature extremes. PPE is often used as a supplement to, not as a substitute for, engineering controls. This program provides general information concerning the most common PPE provided to employees at Jefferson Lab.  In accordance with ES&H Manual Chapter 3210 Work Planning, Control, and Authorization Procedure, Jefferson Lab considers basic, non-specialized PPE to be "Standard Protecting Measures."
Basic, non-specialized PPE at Jefferson Lab includes: 

  • Hard hat,
  • Safety glass with side shields,
  • Safety Shoes,
  • Hearing protection,
  • Face shield,
  • Gloves,
  • Knee pads, and
  • Proper work clothes.

Basic, non-specialized PPE does not protect against exposure to all hazards, (e.g. electricity, welding, etc.). These hazards require specialized PPE, and often, training in its use. See the ES&H Manual chapter applicable to specific hazard tasks for specialized PPE requirements.

Computing and Networking Infrastructure

Web Traffic Protections Expansion Set for Tuesday, Oct. 4
To provide improved security for Jefferson Lab systems, the IT Division will start decrypting web traffic for those systems on the Common User Environment Desktop 3 and any remaining networks on Tuesday, Oct 4. This will allow the automated processes that the lab has in place to scan this traffic and remove identified viruses and malware. To determine what network your desktop is linked via, visit from a web browser on your desktop system. As noted in a previous brief, traffic from known medical and financial institutions will be exempted from decryption, as these are generally not sites from where malware and viruses are deployed. If you have any questions or concerns about this process, contact the IT Division Helpdesk at or x7155.


Bike Rack on North Side of CEBAF Center F Wing Will Be Removed on Sept. 30
The bike rack located along the north side of the CEBAF Center F Wing (adjacent to the K Stairwell) will be removed on Friday, Sept. 30. The rack is currently located where the new mechanical systems are to be placed as part of the computer room upgrade project. With the removal of this rack, CEBAF Center still has accommodations for bikes at the A and C wing entrances. If you have any questions or concerns, contact Bob Sperlazza, x6241.

Jefferson Lab’s Diversity & Inclusion Council Encourages Environment that Accepts and Values Individuals’ Differences and Contributions
Since being formed in 2012, Jefferson Lab’s Diversity and Inclusion (D&I) Council has worked with lab leadership and Human Resources to better understand the value of these concepts, incorporating them into the lab’s culture and core functions, and raising diversity and inclusion awareness across the lab community. Read on to learn more about the council.

Additional TIAA-CREF Individual Counseling Sessions Offered Fall 2016
TIAA-CREF has added two more Individual Counseling Sessions, where you can discuss your personal financial situation with a TIAA-CREF financial consultant on a confidential basis, to be offered at Jefferson Lab on Nov. 22 and Dec. 13 in room 22i in the Support Service Center, Bldg. 28. To schedule an appointment, call TIAA-CREF at (800) 732-8353, Monday through Friday, 9 a.m. – 8 p.m. (ET).  For more information and direct links to other TIAA-CREF resources, see the announcement at this link.

JAG Iron Brew Competition
Jefferson Lab Homebrewers are invited to enter the Iron Brew Competition to take place at the upcoming Jefferson Lab Oktoberfest on Oct. 27. The beers will be judged by a popular vote using a ticketing system. Brewers may bring as many beers for which they have sufficient quantities. JAG recommends that homebrewers who wish to enter the competition should be prepared to bring at least 72 ounces in their preferred format; entries are not limited to any style or ingredient. Bring your best crowd pleaser and some way to keep it cold; tasting cups will be provided for the crowd’s sampling. To enter the contest, contact Daniel Moore at x5927 or and provide a description of the beers you plan to enter, including their style and anything else about them that would be interesting (e.g. special ingredients, process, etc.).
