Flat emitter

Abstract

A flat emitter, in an embodiment, includes an emitter surface to emit electrons when a filament current is applied; a first end region including at least one first connection leg; and a second end region including at least one second connection leg. According to an embodiment, at least one connection leg is embodied as a band-type connection leg and is torsioned at an angle in a longitudinal axis. According to an embodiment, the first connection leg and the second connection leg are embodied as band-type connection legs and in each case are torsioned at a definable angle in a longitudinal axis. As a result, a simply constructed flat emitter in terms of design is achieved, with a longer service life and a high level of electron emission.
