12 GeV Upgrade

Detector construction for the Hall C Super High Momentum Spectrometer continues, with drift chamber stringing progressing at Hampton University and a design readied for the noble gas Cerenkov counter. Machining of the helium vessel has started for the horizontal bend dipole magnet, and the design detailing of the liquid nitrogen shield and vacuum vessel is underway. The machining and water-jet cutting of the steel laminations for the Q1 quadrupole magnet is continuing, with the last steel parts being delivered. Soldering of the copper stabilizer to the superconducting SSC cable for the Q2, Q3 and dipole magnets is complete. Tests of the epoxy impregnation method to be used for the coils of the dipole, Q2 and Q3 magnets were made and production of tooling for this has begun. Installation of the rails for the SHMS support carriage has started, and bids for the main contract to assemble the support carriage are in hand. The needed quantities of boron carbide and plastic flakes for the specialized concrete for the shield house are arriving. Final machining is 40 percent complete for the several hundred tons of Q2, Q3 and dipole magnet steel yokes.

Free-Electron Laser

Design engineering and fabrication of the parts of the new gun continue at a rapid pace. Good progress is also being made on the ring resonator assembly. The full implications of the delay due to the repairs to the Central Helium Liquefier cooling water leak are still under analysis. The FEL team completed a substantial amount of safety documentation updates, including a revision of the FEL Operational Directives Supplement in accordance with OHSAS 18001.

Center for Theoretical and Computational Physics

An important component of the spectroscopy efforts within the Theory Center is the determination of the decay properties of resonances. A recent paper has investigated how finite lattice volume techniques can be used to determine resonance parameters within isospin-1 π-π scattering (the "ρ"). This work will serve as a prototype for the extraction of scattering parameters in more complicated resonant systems.

Environment, Safety, Health and Quality

Visually Impaired Walking

Many JLab staffers and users need corrective lenses to see better, but in some situations, a worker may be unnecessarily degrading their ability see the world. For instance, with a lot of recent office moves and equipment changes, a number of workers have been seen walking with boxes stacked higher than their eyes or so wide they can barely reach the corners (this is an ergonomic issue as well). Any time you are walking but unable to see the path in front of you, you are creating a hazardous situation for yourself and your fellow workers. Instead, choose to carry fewer boxes on each trip or properly load a handcart or dolly to secure and move the items.

The situation can become even more dangerous when a person whose vision is blocked by a load is attempting to navigate stairs. If you can not see the step you are on or the next step that you need to take, you are again creating a hazardous situation for yourself and your fellow workers. One good rule of thumb: If you can't use the handrail because your hands are too full, you should decrease the load or choose to take the elevator with your items loaded onto a handcart or dolly.

Remember: These tips are not only for your own safety, but also for the safety of your fellow workers.

Announcements

Onsite Blood Drive Set for this Friday
The next American Red Cross Blood Drive is scheduled for Friday, Jan. 25, 10 a.m.-4 p.m. in CEBAF Center Room F113. New and repeat donors are encouraged to attend. Appointments and walk-ins are welcome. To schedule an appointment, contact Johnie Banks, x7539.

 

New SOTR Training Feb. 1
A training session (GEN 020) for new Subcontracting Officer's Technical Representatives (SOTRs) will take place on Friday, Feb. 1, 8 a.m.- 12 noon in Room 428 of the Applied Research Center. Anyone tasked to serve as a SOTR on any project at JLab is required to attend this training. Space is limited. To register, contact Betty Beeler, x6999, by 5 p.m. on Thursday, Jan. 31. Anyone with questions regarding this training or the SOTR certification process may call Kathleen Jones at x5139 or Mitch Laney at x5338.

JLab Annual Sustainability Plan Now Available
The 2013 Jefferson Lab Site Sustainability Plan and the Lab Energy Conservation Policy are available for your review. The SSP describes the diverse set of DOE energy, water and greenhouse gas reduction goals, related sustainability initiatives prescribed for each DOE site, and JLab's progress and plans to achieve the goals. The Lab Energy Conservation Policy describes policies specific to JLab, especially regarding use of personal appliances to promote energy conservation and safety. As described in the policy, personal appliances (refrigerators, space heaters, etc.) are prohibited from individual use. However, Facilities Management is prepared and available to provide approved appliances for common use. If you have any questions or comments about these documents, contact Bill Mooney.

Long Shutdown Safety Meeting Video Is Online
JLab staff members who missed the Jan. 10 Long Shutdown Safety Meeting can complete the required training by watching the meeting video and submitting the course completion credit. More information can be found in an All-Staff memo.

Dog-Friendly Landscaping Tips and Therapy Dog Class
Do you think your dog has what it takes to become a therapy dog? Or does your dog dig up your freshly planted pansies every chance he gets? Join the JAG Dog Training Club on Friday, Feb. 8, for a lunchtime meeting to find out about these two contradictions! Michael Andruczyk, Virginia Tech Cooperative Extension Agent, will give a lunchtime talk on "Gardening with Dogs." After Mr. Andruczyk's talk, the JAG Dog Training Club will pass out information on the upcoming Canine Good Citizen/Therapy Dog class, which will begin in mid-February. Bring a bag lunch and join us in the BEAMS classrooms, Support Service Center Rooms 72A/B at noon. For more information, contact Joyce Miller, x7163 or Brian Kross, x7022.

Tracking Thomas at JLab
Little Thomas is visiting all corners of the JLab campus. If you can identify his location this week, email Kandice Carter with your guess. Guesses are accepted through Friday.

No one correctly guessed the location for Jan. 16. Check out the Tracking Thomas webpage for a better view of his last location and this week's new mystery photo.
