Emission Pollution discharged into the atmosphere from smokestacks, other vents, and surface areas of commercial or industrial facilities, from residential chimneys, and from motor vehicle, locomotive, or aircraft exhausts.
Emissions Trading EPA policy that allows a plant complex with several facilities to decrease pollution from some facilities while increasing it from others, so long as total results are equal to or better than previous limits. Facilities where this is done are treated as if they exist in a bubble in which total emissions are averaged out. Complexes that reduce emissions substantially may "bank"their "credits" or sell them to other industries.
Emittance A measure of the quality of a beam with regard to the tightness and uniformity of the momentum of its individual particles. Consider a space where each particle is defined by its position x and its angle x'. Then the emittance is the area of the ellipse enclosing the particles within one sigma (s), defined as above. The emittance (e) is also related to the size of the beam bys = square root eB, where B is the Beta function.
Emma Bump Used in the LINAC as a local closed Bump for one beam. Four correctors are used to create an oscillation in one beam in order to compensate for a wakefield problem while making a closed bump in the other beam. Can be used anywhere in the machine whenever it is necessary to bump only one beam. (Designed by Paul Emma.)
