12 GeV Upgrade

The last of the six Region 3 Drift Chamber sectors for CLAS12 have been installed into the Torus magnet. The six Region 1 Drift Chamber sectors and the six Region 2 Drift Chamber sectors were installed into the Torus magnet previously. Work is proceeding to wire up the low-voltage and high-voltage supplies for these detectors and to prepare the manifolds for the chamber gas. The work on the slow controls for all the drift chamber systems is also nearing completion, in preparation for system testing next month.

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 presents a detailed examination of the kinematical requirements needed for the factorization theorem for semi-inclusive deep-inelastic scattering processes to be valid. The current-region factorization is found to be valid only in a rather restricted range of kinematics, particularly for moderate hard scales. Different kinematical regimes that require new factorization theorems are also identified, and it is argued that the rapidity of the produced hadron is preferred over the usual z parameter for delineating different kinematical regimes.

    Engineering

    For the past few weeks, the Alignment group has been working on the following project.
    • The group has supported Hall A's DVCS experiment with numerous spectrometer pointing surveys and DVCS calorimeter surveys.
    • Hall B's High-Threshold Cherenkov Counter rail was aligned, as was the Silicon Vertex Tracker detector. The Region 1 and Region 2 Drift Chambers were also aligned.
    • Hall C's Super High Momentum Spectrometer Q2 magnet and the Dipole were fiducialized and positioned on the carriage to allow further Hall C work. Q2's yoke was also aligned.
    • For SRF's LCLS-II project, the second cavity string was inspected and fiducialized. Additional work included aligning the support structure in the second bay.
    • In the Upgrade Injector Test Facility, the quarter cryomodule was laid out.
    The Magnet Measurement group completed and assisted on the mapping of Hall B's Torus magnet. Additionally, the group is looking at improving the reliability of the magnet measurement stands and inventory of spare magnets and coils.

    Facilities Management and Logistics

    Material Handling Program Update
    FM&L has moved the Material Handling program to its Operations and Maintenance Group and will be looking to hire a new Material Handling Manager. Until new staff are on board, direct questions or concerns regarding Material Handling procedures, assistance, training, repairs and maintenance to Bob Sperlazza (Manager of Facilities Operations and Maintenance) at x6241.
     
    For Material Handling Equipment Inspections: SOTR's or other requesters should contact Maynard Brown, Russell Mattox and Joe Thomas to request equipment inspection support. The inspectors will coordinate among themselves and keep each other, and the SOTR, informed of who will support the job.
     
    Lift Plans: SOTR's and other lift planners should contact Bob Sperlazza (backup: Rusty Sprouse) with specifics of the lift plan as outlined in the Jefferson Lab ES&H Manual Chapter 6141 Appendix T4. FM&L staff will comment and ultimately approve the final lift plan and coordinate with the lift planner if additional support is required.

    Environment, Safety, Health and Quality

    Protect Yourself During a Thunderstorm
    According to the Centers for Disease Control and Prevention, lightning caused an average of 33 deaths per year in the United States between 2004–2013. We all know that it’s best to seek shelter during a thunderstorm. The CDC recommends an enclosed and substantial, non-concrete shelter (lightning can travel through the metal embedded in concrete). A vehicle can serve as shelter in a storm. If no shelter is available, you can crouch low, with as little of your body touching the ground as possible.

    It’s even possible to be struck by lightning while indoors, with one-third of lightning-strike injuries occurring there. Here are the CDC’s safety tips for sheltering during a thunderstorm indoors:
    • Avoid water during a thunderstorm;
    • Avoid electronic equipment of all types; and
    • Avoid corded phones (cordless or cellular phones are safe to use during a storm).
    For more information about protecting yourself, your family and your colleagues in a thunderstorm, visit the CDC website.
