Process
To achieve the fast evaporation of the material, the power planar density in the beam cross-section must be as high as possible: - values up to 10^7 W/mm^2 can be achieved at the spot of impact. As the electrons transfer their kinetic energy into heat in a very small volume, the material impacted by the beam is evaporated in very short time.

Famous quotes containing the word process:
“I wish to see, in process of disappearing, that only thing which ever could bring this nation to civil war.”
—Abraham Lincoln (1809–1865)
“You can read the best experts on child care. You can listen to those who have been there. You can take a whole childbirth and child-care course without missing a lesson. But you won’t really know a thing about yourselves and each other as parents, or your baby as a child, until you have her in your arms. That’s the moment when the lifelong process of bringing up a child into the fold of the family begins.”
—Stella Chess (20th century)
“It is part of the nature of consciousness, of how the mental apparatus works, that free reason is only a very occasional function of people’s “thinking” and that much of the process is made of reactions as standardized as those of the keys on a typewriter.”
—John Dos Passos (1896–1970)
