When a beam of energetic electrons travels through a plasma, the space charge at the tip of the beam knocks electrons from the ions in the plasma, leaving the ions with a larger positive charge. If ...
SELF-BENDING light beams capable of turning a corner like a boomerang are darting around an optics laboratory in France. The beams are just a few micrometres across, and could improve the way in which ...
Gilson is part of the Virtual National Laboratory for Heavy-Ion Fusion, a partnership between the PPPL, E.O. Lawrence Berkeley Lab and Lawrence Livermore National Laboratory in California. According ...
A pioneering method has emerged for manipulating laser beams using sound waves alone. These days, powerful laser beams are essential in scientific research, from particle accelerators to nuclear ...
When a 'beam' experiences a bending moment it will change its shape and internal stresses (forces) will be developed. The photograph illustrates the shape change of elements of a beam in bending. Note ...
