On Oct. 25, the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility welcomed U.S. Secretary of Energy Jennifer Granholm and honored guests for a short tour of the lab and briefing on its research mission and plans for the future. The delegation interacted with several members of the lab’s community, including CEBAF operations staff, nuclear physicists, engineers, accelerator research scientists and students. Congressional Representatives Bobby Scott and Elaine Luria, Newport News Mayor McKinley Price, and a representative from Senator Mark Warner’s office joined Granholm on her visit to the lab.

Two researchers affiliated with the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility have been selected by their peers for the distinct honor of Fellow of the American Physical Society. The APS announced its 2021 Fellows on Oct. 13.

A new measurement of the neutron skin in calcium reveals that heavier types of calcium nuclei are relatively thin-skinned. The new measurement, made by the 48Ca Radius EXperiment (CREX) collaboration at DOE’s Thomas Jefferson National Accelerator Facility, was presented at the 2021 Fall Meeting of the APS Division of Nuclear Physics of the American Physical Society. It is the first highly robust electroweak measurement of the neutron skin in a medium-weight nucleus, and it features a precision of about 0.025 millionths of a nanometer.

Accelerator scientists at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility have developed a model for a cheaper and easier preparation method for getting better performance from particle accelerators. Preliminary tests show the model may soon provide scientists the ability to predict the best material preparation method for specific performance goals. The results were recently published in Applied Physics Letters.

Andrew Jackura wants to know what we’re made of. Now, as the winner of the 2021 Jefferson Science Associates (JSA) Postdoctoral Prize, he’ll get the chance to find out. Jackura is a postdoctoral research scientist at Old Dominion University and a scientific user at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility. His research focuses on the strong nuclear force, the fundamental force responsible for keeping all ordinary matter in the universe together, including us.

The proton was discovered just over a hundred years ago and has been intensely studied ever since. Yet, there’s still more to learn about this important building block of the visible universe. Now, work toward a better understanding of the proton carried out at the Department of Energy’s Thomas Jefferson National Accelerator Facility has earned Weizhi Xiong the 2020 Jefferson Science Associates (JSA) Thesis Prize.

The Electron-Ion Collider Center at the Department of Energy’s Thomas Jefferson National Accelerator Facility (EIC Center at Jefferson Lab) has announced the winners of six international fellowships to help advance the science program of the Electron-Ion Collider (EIC).

Nuclear physicists have made a new, highly accurate measurement of the thickness of the neutron "skin" that encompasses the lead nucleus in experiments conducted at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility and just published in Physical Review Letters. The result, which revealed a neutron skin thickness of .28 millionths of a nanometer, has important implications for the structure and size of neutron stars.
