12 GeV Upgrade
12 GeV Project installation work in Hall B is increasing in many areas. In addition to welding on the Torus magnet, electrical and electronic work on the power supplies and racks has ramped up. Hall C continues testing and measurements of the Horizontal Bend magnet and power supply, along with preparations for the arrival of additional superconducting magnets in 2016.

Publications Refresher Course Offered Jan. 12, 2016
The next Publications Training and Refresher course will be held on Tuesday, January 12, 2016, at 9 a.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 would like to attend, R.S.V.P. to Kim Edwards by Friday, Jan. 8.
The alignment group has been busy working throughout the lab over the last few weeks. Late September had the group measuring where Hall C's High Momentum Spectrometer was in relation to the straight ahead beam and target. This was to ensure that the HMS and new design post would be in the correct orientation. Additional work in Hall C and upstream 3C line were the Moller quad surveys and Compton measurement. Additionally in September, the crews worked to help the SRF group align their new piers and rails for the upcoming LCLS-II cryomodule construction. Other various work in September included Hall D monument control on the walls, penetration surveys (surveys connecting the accelerator to the surface control), and the 1C12 OTR survey. October saw the crews working on control surveys throughout the accelerator (East and West Arcs, South and North Linacs, Northeast extension). Additionally, the crews worked on the Hall A BCM, the photon detector, and the 1C line Compton magnets and table. In Hall B, an extensive survey was taken of the 12 GeV Torus, establishing the location of the six coils and other prominent features to ensure the Torus's proper alignment. Finally, the crews worked on the UITF (Upgrade Injector Test Facility) project, and are measuring and establishing new alignment control points in the UITF labyrinth.
Facilities Management and Logistics
Construction Near Lawrence Drive and the Walking Trail
Facilities Management personnel expect the clearing of trees from the Jefferson Lab south property boundary to the Lawrence Drive entrance on Jefferson Avenue to begin within the next week. Installation of a 30" diameter sewer force main will follow, beginning in December and continuing into January 2016. Traffic on Lawrence Drive should not be affected until February.
The walking trail is now closed to pedestrian traffic, as it is in the path of the construction. FM&L will evaluate the condition of the trail and advise the Jefferson Lab community on its status once the construction project is complete. If you have any questions or concerns about this work, contact Bob Sperlazza, x6241.
Environment, Safety, Health & Quality
Avoid "Text Neck"
Since the advent of smaller, handheld communication devices, did you ever notice the number of people walking or sitting with their heads bent down? If that position is held static, the stress on the neck and associated muscles will start to cause pain. The average human head weighs 10-12 pounds. When tilting one's head forward, the forces exerted on components of the spine and neck increase many times over. For example, viewing a smartphone held at chest height creates 20-30 pounds of force on the neck. Maintaining a forward head posture can lead to muscle strains, pinched nerves and maybe disc damage. Extended use over months or years can cause the natural inward curve of the cervical spine to flatten, causing even more problems.
You can prevent these issues by taking frequent breaks about every 20 minutes when using mobile devices. The breaks should involve rolling the shoulders and stretching the neck’s muscles by extending the head back, as well as looking away at an object to each side. Smartphones and similar devices are fantastic tools, but use with care in order to prevent unnecessary health problems now and in the future.
