At the frontier between plasmas and accelerators, novel ultrashort X-ray sources are produced using electrons accelerated in laser and electron beam wakefields. Based on radiation from moving ...

Traditional welding utilizes heat from an arc (a spark generated by an electrical discharge) or a laser. Electron beam welders, on the other hand, use the kinetic energy of electrons to bond ...

a physicist at Los Alamos National Laboratory who specializes in laser physics, takes a look at the physics of one such beaming technology—a relativistic electron beam—and how it might be used ...

Enter relativistic electron beams made up of ... Most theoretical studies on "beam riders" for interstellar travel have focused on laser beams, which are composed of particles of light called ...

"At NIF, we use the high-power laser beam instead of an electron beam to make the X-rays by 'crashing' the beam into silver atoms and creating a plasma." The choice of silver is important ...

What are X-Ray Free-Electron Lasers? X-ray free-electron lasers (XFELs ... through a process called self-amplified spontaneous emission (SASE). In this process, a beam of electrons is accelerated to ...
