DEFINITION
Classification: 250/305
(under the class definition) Subject matter having means for or method of separating electrons according to their respective energies (including velocity and momentum) and
detecting the separated electrons.
(1) Note. The separated electrons may include one or more energy level groups.
(2) Note. The separation may occur in static or dynamic electric or magnetic deflecting, focusing or repelling fields.
(3) Note. The electrons usually result from the bombardment of a solid, liquid or gas sample (a) with electromagnetic radiation or charged or neutral particles causing the emission of electrons from the sample or (b) with primary electrons diffracted by or transmitted through the sample.
SEE OR SEARCH THIS CLASS, SUBCLASS:
281+, for similar systems for separating ions according to charge-to-mass ratio. 306+, for electron inspection systems wherein the induced, diffracted or transmitted electrons are detected irrespective of energy level.
396+, for electron deflection systems for deflecting electrons irrespective of energy.
