Using generalized particle distributions: Research collaboration seeks 3-D image of the proton

DOE/Thomas Jefferson National Accelerator Facility

A computed tomography -- CT -- scan can help physicians pinpoint minute cancer tumors, diagnose tiny broken bones and spot the early signs of osteoporosis. Now physicists are using the principles behind the procedure to peer at the inner workings of the proton. In a recent experiment, members of Jefferson Lab's Deeply Virtual Compton Scattering collaboration found that it will be possible to construct three-dimensional images of the building blocks of the proton.

Studying the universe through pions

DOE/Thomas Jefferson National Accelerator Facility

Pions are some of matter's simplest particles. They're built from the same building blocks as protons and neutrons -- quarks. The pion is the simplest particle built of quarks. The quarks are "glued" together by the strong force -- a fundamental force of nature that also binds quarks to form protons and neutrons. Studying the simple pion and its properties can reveal information about matter in the universe, where it came from and how it's held together.

Scientists study how the strong force builds the lightest particle made of quarks -- the pion

DOE/Thomas Jefferson National Accelerator Facility

In Jefferson Lab's Hall C, an international collaboration of nuclear physicists, the Fpi collaboration, is studying how the strong force combines nature's fundamental building blocks into the lightest particle built of quarks -- the pion.

Reaching new heights in accelerator technology

DOE/Thomas Jefferson National Accelerator Facility

The International Linear Collider is designed to collide high-energy electrons with high-energy positrons (electrons' antimatter counterparts). Once built, the ILC will serve as a powerful tool for scientists to address many of the most compelling questions of the 21st century -- regarding the fundamental nature of matter, energy, space and time, dark matter, dark energy and extra dimensions.

Researchers' hottest new laser beams 14.2kW

DOE/Thomas Jefferson National Accelerator Facility

On Oct. 26, Free-Electron Laser (FEL) team members knew they were within reach of a goal they'd pursued for two years. They were aiming to produce 10 kW of laser light at an infrared wavelength of 1.61 microns. On that day, they blew past the milestone to produce 11.7 kW. Just four days later, on Oct. 30, they coaxed another two kW out of the machine setting the record even higher at 14.2 kW.

Lab enhances scientific data sharing with cutting-edge connection

DOE/Thomas Jefferson National Accelerator Facility

In early 2005, researchers affiliated with Hall B wanted to transfer raw data from a recent experiment from the tape silo to computers offsite -- a task that without interruption would have taken the Lab's existing network connection almost seven days. Jefferson Lab's newly upgraded network connection is able to transfer data at a rate of up to 10 Gigabits per second, so that same transfer can now be completed in just 2.5 hours.

Big bite is reborn

DOE/Thomas Jefferson National Accelerator Facility

At Jefferson Lab's recent Users Meeting, DOE's Dennis Kovar and NSF's Brad Keister emphasized the funding agencies' commitment to pursuing a cohesive nuclear physics research program in the United States. For instance, Jefferson Lab is funded by DOE; however, NSF provides for many of the Lab's Users and students and some of the instrumentation used in experiments, such as the recently upgraded BigBite spectrometer.

Innovative energy-saving process earns Jefferson Lab Team a 2007 White House Award

DOE/Thomas Jefferson National Accelerator Facility

A series of innovative energy-saving processes invented by engineers at the US Department of Energy's Thomas Jefferson National Accelerator Facility today were celebrated with a prestigious White House Closing the Circle Award during ceremonies in Washington, DC.

Grant and Award Announcement

Michael Haddox-Schatz, a computer programmer at the Department of Energy's Thomas Jefferson National Accelerator Facility, out-coded more than 20,000 participants to win a spot in Google's Global Code Jam 2006 Championship Round. Out of 100 finalists, Haddox-Schatz is one of just seven savvy programmers from the United States set to take part in the Oct. 27 finals in New York City.
