Hall D Update
The first physics run of the GlueX experiment is progressing in Hall D, as planned. About 50 billion events have been recorded so far. During the remaining two weeks of beam, it is expected to accumulate more data as well as perform various specialized measurements needed for the GlueX physics program.

Last Chance to Apply: JSA/JLab Graduate Fellowship Program
The JSA/JLab Graduate Fellowship Program contributes to addressing the nation's commitment to grow our future science leaders and researchers by providing the environment and financial resources for graduate students to work alongside Jefferson Lab researchers. Application materials are due by March 10. More information and application requirements can be found online.

Apply Now for Sabbatical and Research Leave Support at Jefferson Lab
The JSA/JLab Sabbatical and Research Leave Support Program enhances research opportunities for faculty through access to Jefferson Lab facilities and interaction with Lab researchers and users, strengthens the teaching and research capabilities of universities through faculty involvement, and strengthens the research programs of Jefferson Lab by attracting "new blood" and integrating university faculty members in the laboratory's programs. Application materials are due by March 31. More information and applications requirements can be found online.

    Center for Theoretical and Computational Physics

    A new Theory Center paper asks the question: What are the low-Q and large-x boundaries of collinear QCD factorization theorems? Using an idealized field-theoretic model that contains the essential elements that a factorization derivation must confront, the paper retraces the steps of factorization approximations and compares with calculations that keep all kinematics exact. It examines the relative importance of the target mass, light quark masses and intrinsic parton transverse momentum, and it finds that a careful accounting of parton virtuality is essential for treating power corrections to collinear factorization for moderately low-Q and large-x physics.

    Engineering

    The Installation and Vacuum groups spent an extensive amount of time during the winter scheduled accelerator down period completing many tasks, such as acid flushing all the box power supplies, installing the repaired 750 MHz RF Separator girder and replacing the last of the linac valve position switches with the all-metal upgrades. The group then moved to tasks to support the demonstration runs for the 12 GeV Project Key Performance Parameters in Halls B and C. Additionally, the group completed more infrastructure work in the Upgrade Injector Test Facility.

    Limited Access to CEBAF Center F-Wing First Floor on March 11-12
    This coming weekend, Warwick Plumbing & Heating subcontractors will be spraying foam in the Data Center as part of the Utilities Infrastructure Modernization (UIM) Data Center Upgrade project. There will be limited access on the first floor F-wing hallway on Saturday, March 11, due to spray foam hoses. Additionally, a slight odor will be present inside the Data Center likely throughout the weekend (the space will be ventilated for 24 hours after foam is sprayed). It's recommended that staff and Users avoid the first floor of the F-wing over the weekend. If you have any questions or concerns about this work, contact Michele Solaroli, x7751.

    Deadly Dozen Unsafe Conditions that Can Lead to Accidents
    Many accidents can be avoided my recognizing unsafe acts or conditions and correcting them. Following up on last week’s brief on unsafe acts, here is a list from the Washington State Department of Labor and Industries of a dozen common unsafe conditions that can lead to preventable accidents:

    1. Lack of proper guards.
    2. Lack of a proper warning system.
    3. Fire and explosion hazards.
    4. Poor housekeeping.
    5. Unexpected movements.
    6. Protruding objects, such as nails, wire, or other metals.
    7. Improper clearance or congestion at aisles or passageways.
    8. Poor placement, storage or arrangement of materials.
    9. Hazardous tools, equipment or materials.
    10. Poor lighting and high noise levels.
    11. Hazardous atmospheric conditions.
    12. Improper personal attire.
     
    Remember, when you recognize the act or condition that could lead to an accident and you effectively correct or avoid it, you reduce the potential for an accident.

    Food Services Subcontractor Update
    The transition of the food services subcontract from Eurest to Elite Management Group is underway. The first meeting between the lab and the new subcontractor was held last Friday to begin the process. Elite will assume operations on April 3, and the subcontractor plans to continue menus and offerings similar to what we currently enjoy through the month of April, with the goal of a grand reopening of the Cafe on May 1. More details will be shared as the process unfolds and plans are finalized. Questions may be directed to Staff Services Manager and SOTR, Cynthia Lockwood, at lockwood@jlab.org or x7389.

    DOE Scientific and Technical Information Newsletter Notice
    DOE conducts more than $11 billion a year in R&D, and DOE’s Office of Scientific and Technical Information (OSTI) maximizes the reach and impact of these investments, both through its own search tools and through other commonly used search engines. OSTI also publishes a quarterly newsletter that provides useful information about its activities and resources. If you would like your name added to the subscription list, send an email to newsletter@osti.gov with SUBSCRIBE in the subject line. You can peruse past issues at this link.

    Nysmith Wins 2017 Virginia Middle School Science Bowl
