WELCOME HALL C COLLABORATION!
Scientists who conduct research in our Experimental Hall C meet this week to discuss current work and future plans - Hall C is used to study form factors and 3-D structure of simple quark systems, and short range structure in nuclei.
WELCOME HALL A COLLABORATION!
Researchers who conduct experiments in Jefferson Lab's Experimental Hall A meet this week to discuss research conducted here. Hall A is configured with two High Resolution Spectrometers for precise measurements of the inner structure of the nuclei.
TENSION IN THE TENSOR CHARGE OF THE NUCLEON
The tensor charge of the nucleon, and the associated transversity distributions of quarks in the nucleon, are fundamental quantities that provide information about the internal substructure of the nucleon. Some tension has existed between the values of the tensor charge extracted from phenomenological QCD analyses of high enegry scattering data and calculations based on lattice QCD. A new paper examines the role of certain assumptions made in the phenomenological analyses, and shows that by relaxing some of these, the observed tension can be decreased.
DETERMINATION OF QCP PARAMETERS FROM A GLOBAL BAYESIAN ANALYSIS
On Monday, Feb. 10, Steffen Bass of Duke University will review the Bayesian analysis and discuss recent progress in determining QCP initial conditions and transport coefficients. As a reminder, to stay informed about upcoming Theory seminars sign up for their mailing list or check their seminar calendar.
2020 BEAMS ROLE MODEL VOLUNTEERS NEEDED
The Science Education Team is on the hunt for volunteers to serve as BEAMS (Becoming Enthusiastic about Math and Science) Role Models. Role Models provide students with insight into their position at the lab, why they do what they do, and what makes it all fun! By sharing your role at the lab, students are able to visualize their learning and its application in the real world. You don't have to be in a math or science field to participate; anyone can share! Volunteer sessions are only fifteen minutes long. Read about the full BEAMS program here. To sign up, click here. For questions, contact Rhonda Bell at x7663.
HIGH SCHOOL SCIENCE BOWL - FEB. 1
Jefferson Lab will host the Virginia Regional High School Science Bowl for the 19th Year on Saturday, Feb. 1, 2020. Participating teams face off in an intense question-and-answer format, where contestants are quizzed on their knowledge of math and a range of science disciplines, including Biology, Chemistry, Earth Science, Physics and Energy. The winning team will be provided with an expenses-paid trip to the National Science Bowl® finals to be held in Washington, D.C., April 30-May 4. Read the full media advisory here. For questions or to volunterr, contact Steve Gagnon at x6286.
CORPORATE COMMUNICATIONS WRITING WORKSHOP SERIES
Words matter. That goes for any writing, for any of us, here at the lab. Striving together to make them better brought about this writing workshop series in corporate communications, starting Feb. 11. These four bring-your-lunch-and-learn weekly sessions range from “universal truths” on writing in general to tips on writings both long form (reports, plans, etc.) and short (memos, emails, etc.). Altogether, they’ll equip you for better writing…no matter where you work. Register at jlab.org/CorporateComm. Questions? Contact Dave Bounds at x5102.
IMPROVING PARTICLE ACCELERATORS WITH MACHINE LEARNING
A new project aims to use machine learning to improve up-time of particle accelerators. “Machine learning is quickly gaining popularity, particularly for optimizing, automating and speeding up data analysis,” Anna Solopova, JLab staff member says. “This is exactly what is needed to reduce the workload for SRF cavity fault classification.” If successful, the project would also open the possibility of extending the model to identify precursors to cavity trips, so that operators would have an early warning system of possible faults and can take action to prevent them from ever occurring. The project has been funded by Laboratory Directed Research and Development (LDRD) program. Learn more about the project here.
TODD KUJAWA ACHIEVES CERTIFIED ELECTRICAL SAFETY COMPLIANCE PROFESSIONAL CERTIFICATION
A message from COO, Mike Maier: Jefferson Lab is pleased to recognize Todd Kujawa of the Facilities Maintenance and Logistics Division as the first JSA employee to receive the Certified Electrical Safety Compliance Professional certification from the National Fire Protection Association. To get this certification an electrical or electronics worker must have at least four years of documented work experience on electrical systems and pass a difficult written test on the requirements of NFPA 70E. Jefferson Lab adopted a goal of developing a small cadre of CESCP certified staff members in the major electrical and electronics work performing divisions to build out expertise on this important standard across the front line of our workforce. Having people like Todd reach this high level of professional certification demonstrates their individual commitment to advance our safety culture as they become important resources of electrical safety expertise for other staff members. Other electrical and electronics workers at Jefferson Lab interested in pursuing their CESCP certification should contact Tim Fitzgerald of ESH. All certification costs are borne by Jefferson Lab.
CHESAPEAKE REGIONAL MOBILE MAMMOGRAPHY ON-SITE - JAN. 31
The Chesapeake Regional Mobile Mammography Unit will be at Jefferson Lab on Jan. 31 from 9 a.m.-3 p.m. It will be stationed in the Applied Research Center (ARC) parking lot. Both 2D and 3D options are offered. This service is open to all employees, Users, contractors, etc. as well as their family members or friends. Personal health insurance will be billed. There must be a minimum of 8 appointments for them to come on-site. We're about half way there so make your appointment by calling (757) 312-6400 or visiting www.chesapeakemammo.com.
JSA POSTDOCTORAL RESEARCH PRIZE DEADLINE - FEB. 7
Calling all postdocs in nuclear physics! Apply now for the JSA Postdoc Prize, which comes with a $10,000 grant for your research project. Applications are due Feb. 7. To learn more, click here. To read about last year's winner, click here.
BLOOD DRIVE - FEB. 19
The American Red Cross Blood Drive is returning to lab campus! Save a life (or several!) by donating blood Wednesday, Feb. 19, from 10 a.m.-4 p.m. in CEBAF Center room F113. The American Red Cross has a critical blood shortage and has issued an emergency request for eligible blood and platelet donors. Severe winter weather and seasonal illnesses have greatly impacted supplies. Right now the Red Cross has less than a 3-day supply of type O blood. New and repeat donors are encouraged to attend, and walk-ins are always welcome. To see if you are eligible to donate, click here. To schedule your appointment, click here and use the sponsor code "TJNAF." For more information, contact Johnie Banks at x7539.
EMPLOYEE SPOTLIGHT: KATHERINE WILSON
Staff Engineer Katherine Wilson knows that precision is indispensable in her field. Yet, getting to the point where precision matters takes constant communication. The French major, former NASA co-op master’s student and one-time shipyard engineer recognizes that her role requires an amalgam of her finely tuned skills, which extend beyond engineering.Wilson values the creativity she gets to practice in her role — and recognizes that she is drawn to projects that have clear boundaries around them.
“I’m creative in orderly ways,” she laughs. “Engineering is a good way to be creative. You get to follow rules, structure and techniques, and you can still come up with something entirely new.”
