Abstract
The present invention provides an emitter, which comprises carbon nanotubes and is excellent in the efficiency of electron emission, and an X-ray tube comprising the same.
Claims14
An emitter, which comprises:
- a first tube composed of a carbon nanotube sheet that comprises a plurality of unit yarns having a structure in which a plurality of carbon nanotubes are aggregated and extend in a first direction;
- and
- a conductive wire that occupies at least a part of the first internal space,
- wherein at least a part of the first tube surrounds and contacts at least a part of the conductive wire,
- wherein the first tube is in the form of a pipe having a first internal space in which the carbon nanotube sheet is rolled about an imaginary first axis parallel to the first direction, and
- wherein respective front ends of the unit yarns are oriented in the same direction as the axis.
