Wim Leemans is the founder and head of the Laser Optical Systems Integrated Studies (LOASIS) program and director of the Berkeley Lab Laser Accelerator (BELLA) program in Berkeley Lab’s Accelerator and Fusion Research Division. A native of Belgium, Leemans joined Berkeley Lab in 1991. As the leading pioneer of laser wakefield acceleration, with its promise of accelerating power up to 10,000 times greater than today’s conventional accelerators, he and his colleagues have made a series of key advances demonstrating that laser plasma accelerator technology is not only theoretical but practical.
In 2004 the LOASIS team used a unique focusing concept of plasma channels, analogous to optical fibers, to achieve high-quality electron beams of 80 million electron volts. In 2006 LOASIS researchers garnered worldwide attention by using a plasma channel in a block of sapphire to demonstrate acceleration of high-quality electron beams to a billion electron volts in a distance of just 3.3 centimeters. With DOE support Leemans and the LOASIS Program have now initiated the Berkeley Lab Laser Accelerator, BELLA, using petawatt lasers to accelerate a high-quality beam of electrons to 10 billion electron volts in less than a meter. Although primarily a research facility for investigating advanced accelerator concepts, the BELLA laser accelerator could form the core of a user facility unlike any in the world for research in physics, chemistry, biology, and materials.
