Publications Refresher Course Offered on Oct. 16
Brush up on the Jefferson Lab Publications Process by attending this course. The lab must submit the final, peer reviewed, accepted manuscripts to the Department of Energy. To learn how to do this, you can visit this webpage or come to the next Publications Training and Refresher course on Monday, Oct. 16 at 9 a.m. in CEBAF Center room F228. 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 will attend, R.S.V.P. to Kim Edwards by Friday, Oct. 13.

    Center for Theoretical and Computational Physics

    Recent experimental results suggest there is a rich spectrum of states in the charmonium sector of QCD. In a new paper, a general class of operator constructors are presented that allow for lattice QCD-based calculations to probe for the existence of tetraquark objects within the spectrum of the theory. Using these constructions, the lattice calculations find no strong indication of a bound state or narrow resonance in the channels that were studied.

    Environment, Safety, Health and Quality

    Dealing with The Unknown
    By now, you should have heard about the "burning pipe" found on SURA property during an environmental inspection. This event serves to remind us that despite our collective efforts to identify and understand all potential workplace hazards, there remains the possibility for surprises. Jefferson Lab's ES&H Manual Chapter 2410 Appendix T1 Hazard Issues List summarizes the various hazards that have been identified, along with a list of staff who can provide you with assistance to identify and protect yourself and your coworkers from those hazards. However, that list does not contain information on what to do about a burning pipe, because that scenario was unexpected. You could potentially encounter other hazards that are unfamiliar to you for various reasons. If that happens, the best approach is to back away, keep others away, and call security at x5822 or ESH&Q at x7611 for help.

    Announcements

    Volunteers Needed to Help Staff Table at NASA Langley’s Centennial Open House on Oct. 21
    On Saturday, Oct. 21, the NASA Langley Research Center gates will open to the public for its Centennial Celebration Open House. Jefferson Lab will have an informational table and activity space at the event. While a member of JLab’s Science Education team will be staffing the table throughout the day, volunteers are also needed to assist. Science Education is seeking one volunteer for each of four two-hour slots. For more information and to volunteer, see the full memo.

    More Info: Mandatory National Security Training Due Friday, Oct. 6
    Secretary Perry has directed all DOE Federal employees and contractors to view a national security briefing no later than this Friday, Oct. 6. At Jefferson Lab, this requirement extends to everyone who receives a paycheck from Jefferson Science Associates, LLC. Once you complete the video, you must acknowledge that you have reviewed it by clicking "YES" on the final screen. You can then log back in to view and print the certificate of completion (under Review Course) to keep for your records. For more information about the requirement and a link to the video briefing, see the full memo.

    Two Jefferson Lab Researchers Receive DOE Early Career Awards.
    Two researchers affiliated with the Jefferson NLab have received 2017 Early Career Research Program awards from the DOE’s Office of Science. Ted Rogers, who holds a joint appointment position with Jefferson Lab and Old Dominion University, and Justin Stevens, who holds a bridge appointment position with Jefferson Lab and William & Mary, were among the 59 winners recently announced by DOE. See the full story.

    Reminder: Ethics Training for Supervisors/Managers
    A key factor in Jefferson Lab's success is maintaining an ethical culture, where our people and processes are viewed with trust and integrity. To ensure the laboratory maintains the highest standards of ethical conduct, and to create a deeper awareness of the roles and responsibilities of members of management, all supervisors and managers must complete an in-person training session as part of the annual Standards of Ethics and Code of Conduct training by the end of the calendar year. If you have not already, you may see all open class dates and register for the class, Maintaining an Ethical Culture Inside & Outside Jefferson Lab (MGT105), in the Learning Management System.

    Jefferson Lab to Test Tornado Warning Siren at 10:30 a.m. on Friday, Oct. 6
    Jefferson Lab's tornado warning siren will undergo its monthly operational test at 10:30 a.m. on Friday, Oct. 6. Don't respond to the siren; this is a test of the siren system and not a personnel response exercise. Individuals planning to be in the Central Materials Storage Area (where the siren is located) while the test is taking place must have with them and wear two layers of hearing protection.

    Performance Appraisal Process Is Now Underway
    Jefferson Lab's performance review cycle is Oct. 1-Sept. 30 each year. Once your supervisor has accessed the Performance Appraisal system and activated our performance appraisals, you will receive an email indicating that your appraisal is active and ready for completion. You can review the full memo for more information on the performance appraisal process and deadlines for completion.

    United Way Annual Ice Cream Social Set for Oct. 9
    The entire Jefferson Lab community is invited to kick off the annual United Way of the Virginia Peninsula Campaign with an Ice Cream Social. The social will be held Monday, Oct. 9, in the CEBAF Center lobby at 11:30 a.m.- 1:30 p.m. This year, members of lab leadership will be on hand to serve up ice cream and dress it with your favorite toppings. Donate just $1 per scoop (up to 3 scoops per bowl). All proceeds will go to the United Way of the Virginia Peninsula. The food is being generously donated by our Quark Cafe contractor, Elite.
