Article Free Physics Laboratory is state-of-art center for research into beam physics and accelerator technologies. Relativistic particle beams and accelerators which produce them have served as cutting edge tool in scientific research for three-quarters of century. Practitioners of accelerator science can be placed in tradition of instrument development dating back to Galileo. In present time, beam physics is vibrant, cross-disciplinary enterprise, which intersects heavily with high-energy density science, plasma physics, ultra-fast lasers, nonlinear dynamics and various high-field/high-power technologies. In addition, applications extend from energy frontier in particle physics, to ultra-fast phenomena in biology and materials, and to industrial and medical uses.
