For over a year, the LOASIS group led by Wim Leemans, of Berkeley Lab’s Accelerator and Fusion Research Division (AFRD), has held the world record for laser-wakefield acceleration, accelerating high-quality electron beams to energies exceeding 1 GeV, a billion electron volts, in a distance of just three centimeters. Now Leemans and his colleagues are [...]

The nickname “tabletop accelerator” may be a metaphor, but laser wakefield accelerators are still remarkably compact by comparison with traditional particle accelerators whose length is measured in kilometers.

Femtosecond lasers have been around since the 1980s, their pulses measured in quadrillionths of a second (10-15 second). The turn of the 21st century saw the achievement of attosecond pulses, lasting mere billionths of a billionth of a second (10-18 second). Now particle accelerators, and experiments that depend on them, [...]

BERKELEY, CA — The National Center for X-ray Tomography (NCXT) has officially been dedicated at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). Located at Berkeley Lab’s Advanced Light Source (ALS), this new center features a first-of-its-kind x-ray microscope that will enable scientists to perform “CAT [...]

BERKELEY, CA — In a precedent-shattering demonstration of the potential of laser-wakefield acceleration, scientists at the Department of Energy’s Lawrence Berkeley National Laboratory, working with colleagues at the University of Oxford, have accelerated electron beams to energies exceeding a billion electron volts (1 GeV) in a distance of just 3.3 [...]

Those who wander Berkeley Lab’s hallways or surf the Lab’s intranet are familiar with the art of Robin Lafever: spectacular images of the proposed SuperNova/Acceleration Probe (SNAP) satellite; the Silicon Vertex Tracker built for the BaBar detector at the Stanford Linear Accelerator Center’s B-Factory; GRETINA, the most sensitive gamma-ray detector ever devised, [...]

A paper titled “Observation of antiprotons,” by Owen Chamberlain, Emilio Segrè, Clyde Wiegand, and Thomas Ypsilantis, members of what was then known as the Radiation Laboratory of the University of California at Berkeley, appeared in the November 1, 1955 issue of Physical Review Letters. It announced the discovery of a new subatomic [...]
