Beam-powered propulsion — is a class of spacecraft propulsion mechanisms that use energy beamed to the spacecraft from a remote power plant. Most designs are rocket engines where the energy is provided by the beam, and is used to superheat propellant that then provides… … Wikipedia
Forward planning — is a technique used in external beam radiotherapy to produce a treatment plan. In forward planning, a treatment oncologist places beams into a radiotherapy treatment planning system which can deliver sufficient radiation to a tumour while both… … Wikipedia

Electron beam lithography — (often abbreviated as e beam lithography) is the practice of scanning a beam of electrons in a patterned fashion across a surface covered with a film (called the resist),cite book |last= McCord |first=M. A. |coauthors=M. J. Rooks |title=… … Wikipedia
Proximity effect (electron beam lithography) — The proximity effect in electron beam lithography (EBL) is the phenomenon that the exposure dose distribution, and hence the developed pattern, is wider than the scanned pattern, due to the interactions of the primary beam electrons with the… … Wikipedia
