A VACCUM-SEALED MINIATURE X-RAY TUBE BASED ON CARBON NANOTUBE FIELD EMITTERS |
摘要 |
PURPOSE: A small vacuum sealed X-ray tube using an electronic beam emitter based on carbon nanotube is provided to solve the X-ray output, X-ray generation reaction speed, power consumption, and microminiaturization limits of an existing thermal electron beam source by using an electron beam source of a carbon nanotube cold-type field emission type. CONSTITUTION: An electron beam generator (200) includes a focusing electrode (130) formed in a cylindrical shape. The electron beam generator emits electronic beam through a carbon nanotube electronic beam emitter (110) which is inserted into the center of the focusing electrode. A ceramic tube (160) functions as an insulator for blocking a high voltage. An X-ray target (180) comprises an X-ray transmission window (150) for radiating ionizing radiation into the atmosphere and an X-ray target layer (140). A connection anode (170) is provided between the X-ray target and the ceramic tube. |
