12 GeV Upgrade
The Torus magnet for CLAS12 has been parked at a temperature of 80 Kelvin for the past two months awaiting the upcoming beam run in Hall B. t will be brought back down to liquid helium temperature at the end of January to prepare for the run. The drift chambers have all been suspended from the Torus cryostat and had their services attached, and the Forward Carriage has been rolled upstream to its operating position next to the Torus.
The five coils of the Solenoid magnet have now been spliced into one continuous circuit, and the resulting magnet “cold mass” has been covered with reflecting aluminum foil. The radiation shields are now being fit to the outer circumference of this assembly. After this step, the multi-layer insulation blankets will be added and then the entire assembly will be suspended inside the cryostat outer shell; eight suspension links are welded to the cryostat and then attached to the cold mass by insulating links in this step. The conical end regions and the bore tubes of both the radiation screen and the cryostat were prepared earlier and will be attached after the cold mass is suspended from the cryostat outer shell in order to close the cryostat. Planning for shipping the Solenoid to Jefferson Lab is well underway, including the final steps in the design of the shipping cradle and isolation springs needed for the road trip to Virginia.
L’Oréal-UNESCO For Women in Science Program Applications Due Feb. 3
The L’Oréal-UNESCO For Women in Science program recognizes and rewards the contributions women make in STEM fields and identifies exceptional women researchers committed to serving as role models for younger generations. More than 2,250 women scientists in over 110 countries have been recognized since the program began in 1998. In the U.S., the program awards five postdoctoral women scientists annually with grants of $60,000 each. Applicants are selected from a variety of fields, including the life and physical/material sciences, technology (including computer science), engineering and mathematics. Applications for the program are now open and are due on Friday, Feb. 3. The application and more information can be found at the link.
Nominate A Colleague for the 2017 Outstanding Nuclear Physicist Award
JSA is now accepting nominations for the 2017 Outstanding Nuclear Physicist Award, which recognizes individuals who have made outstanding and sustained contributions, including technical achievements, to experimental and/or theoretical research related to the nuclear physics program at Jefferson Lab. The biennial award consists of a certificate and a $10,000 honorarium, presented to the honoree at the Jefferson Lab Annual Users Group meeting. Deadline for submissions is Jan. 31, 2017. See details and poster online.
Center for Theoretical and Computational Physics
A new paper shows how a thorough amplitude analysis of the data available for the Zc(3900) peak, seen by BESIII and Belle, can help with constraining phenomenological models. It discusses possible scenarios of a QCD state, a virtual state, or a kinematical enhancement. Although the current data are not precise enough to distinguish between these hypotheses, the proposed method may shed light on the nature of these exotic enhancements when applied to data from forthcoming high-statistics measurements.

Winter Weather: Watch for the Warning
Winter weather advisories inform you when weather conditions are expected to cause significant inconvenience or hazardous conditions. Here's a brief explanation of the most common advisories that may be issued soon regarding winter weather:
- When a "Winter Storm Watch" is issued, it means that the National Weather Service predicts that severe winter conditions, such as snow or ice, will be in the area within 12 to 36 hours. At the time a watch is announced exactly where, when and how much is still not certain. The intent of a watch notification is to provide enough lead time for you to prepare for the event.
- When a "Winter Storm Warning" is issued, it means that the National Weather Service is forecasting four or more inches of snow or sleet in the next 12 hours, six or more inches of sleet or snow in the next 24 hours, or 1/4 inch or more of ice accumulation.
The Emergency Management Team monitors all types of weather conditions and has plans in place to provide notifications to staff and users in the event of severe weather conditions. Facilities Management & Logistics is also prepared for winter weather, and plans are in place for a variety of situations.
Computing and Networking Infrastructure
IT Maintenance Day, Tuesday, Jan. 17, 5-7 p.m.
The IT Division is planning a maintenance period on Tuesday, Jan. 17, 5-7 p.m. During this time, there may be a couple of short network outages while the campus firewall is upgraded. Windows and Linux patches will be released to managed desktops and servers. There may be short outages overnight while these servers are rebooted to finalize patch installation. Also, plan on rebooting your Windows or Linux desktop no later than Friday, Jan. 20, to finalize patch installation. If you have any questions or concerns regarding the maintenance period, contact the IT Division Helpdesk at email@example.com or x7155.
Jefferson Lab MFA Roll-Out Continues
More than 200 multi-factor authentication (MFA) smartcards were passed out in December. If you require a smartcard and have not yet received one, see the latest card issuance schedule and other information on the website.
Sentara Mobile Mammography Unit On-Site January 13
Appointments are still available for the Sentara Mobile Mammography Unit, which will be here at Jefferson Lab on January 13, 2017, 8:30 a.m.-3 p.m. It will be stationed in the ARC parking lot. Mammography detects breast cancer, and The American Cancer Society recommends that women with an average risk of breast cancer should undergo regular screening mammography starting at age 45. It only takes 15 minutes! This service is open to all employees as well as their family members or friends, since personal health insurances will be billed. To make an appointment, call 757-261-5420 and select option 1.
Volunteers Sought to Help with Engineering/STEM Career Days on Feb. 23-24
Jefferson Lab will be participating once again in the Engineering/STEM Career Days on Thursday, Feb. 23, and Friday, Feb. 24, 2017, 8 a.m.-1 p.m., at Newport News Shipbuilding. Science Education is seeking engineers, scientists and technicians who are willing to talk to high school students about their careers. The day is formatted as such: The high school students will rotate through four preassigned tables, each staffed by one of our JLab volunteers. For each 15 minute rotation, our staff will talk about their careers, backgrounds, etc. Upon completion of the final rotation, students will stay at that table to participate in a design challenge (which Science Education will provide). Then event will conclude with lunch! If you are interested in volunteering or have questions, contact Brita R. Hampton at firstname.lastname@example.org by Wednesday, Jan. 25. Volunteers may sign up for one day or for both days.
Red Cross Blood Drive Scheduled for Tuesday, Jan. 24
The next American Red Cross Blood Drive will take place Tuesday, Jan. 24, 10 a.m.-4 p.m. in CEBAF Center room F113. New and repeat donors are encouraged to attend. Walk-ins are welcome. All participation is greatly appreciated. To schedule an appointment, visit redcrossblood.org and enter Sponsor Code: TJNAF. You can also schedule an appointment by contacting Johnie Banks at email@example.com or x7539. Visit the website for donation eligibility requirements.
