Sentences with phrase «quality electron beam»

Unlike conventional lasers, which use mirrors to amplify the light they create, free - electron lasers rely on a high - quality electron beam and an array of magnets.

It could potentially improve the quality of plasma spray applications and reduce the cost of the more expensive higher quality electron beam physical vapor deposition, EBPVD, applications.

Not exact matches

However, the quality of electron beams has only recently become good enough to enable femtosecond studies.

However, the technique has yet to overcome a major challenge: Strong forces pointing toward the center of the plasma can degrade the quality of the particle beam, which consists of bunches of electrons or positrons.

Dwight Duston, director of science and technology at the Pentagon's Star Wars office, says the free - electron laser, once trumpeted as a weapon for destroying incoming enemy missiles, could be used to produce a beam of high - quality X-rays that would reduce a woman's exposure to radiation during mammography.
