Berkeley Lab’s lead in laser plasma acceleration research continues with new benchmarks for electron beam quality
Part One: Focusing in on beam focus
The rapidly evolving technology of laser plasma accelerators (LPAs) – called “table-top accelerators” because their length can be measured in centimeters instead of kilometers – promises a new breed of machines, far less expensive and with far less impact on the land and the environment than today’s conventional accelerators.
Future LPAs offer not only compact high-energy colliders for fundamental physics but diminutive light sources as well. These will probe chemical reactions, from artificial photosynthesis to “green catalysis”; unique biological structures, inaccessible to other forms of microscopy yet essential to understanding life and health; and new materials, including low-temperature superconductors, topological insulators, spintronics devices, and graphene nanostructures, which will revolutionize the electronics industry. With intensely bright beams spanning the spectrum from microwaves to gamma rays, table-top accelerators will open new vistas of science. (more…)
