Portrait of a Gremlin

April 30 , 2008. A novel way of looking inside accelerator components has given scientists their first clear snapshot of a performance-killing defect. Researchers suspect that the tiny blob (about the width of a human hair) on an otherwise smooth surface is preventing the component being tested at Jefferson Lab from reaching its design specifications.

Toward Speeding Wound Healing

March 31, 2006. Deep inside a mouse's body, foreign cells are glowing. The glowing cells are the first step in developing a new therapy for shortening the amount of time it takes wounds to heal. Carl Zorn of Jefferson Lab's Detector and Imaging Group and Zhenghong Lee at Case Western Reserve University in Cleveland discuss how the same technology found in digital cameras is helping scientists develop this new therapy.

Nuclear Physics in Breast Imaging

January 11, 2006. The technology behind the detectors used in Jefferson Lab experiments is imaging cancer in the breast. Used alongside mammograms, the technology is aiding doctors in the fight against breast cancer. Jefferson Lab's Detector and Imaging Group (Group Leader Stan Majewski and member Drew Weisenberger) and Dilon President, Lon Slane, talk about how the technology works and how it's saving lives.

Supercomputing on a Shoestring

November 7, 2005. Cluster computers are tackling computations that were once reserved for the most powerful supercomputers. Jefferson Lab's clusters are calculating the theory that corresponds to the nuclear physics experiments, giving scientists another tool to explore the basic building blocks of matter.

Spin Structure of Protons and Neutrons

September 19, 2005. Just as a top spins on a table, the tiny quarks inside protons and neutrons also spin. Now a complex calculation by theoretical nuclear physicists at Jefferson Lab has revealed that a quark's spin may be altered by the surroundings of the proton or neutron in which it resides. This surprising result, recently published in the journal Physical Review Letters, may lead to new insights about how ordinary matter is constructed.
