SUPER MINIATURE X-RAY TUBE USING CARBON NANOTUBE FIELD EMITTER

摘要

PURPOSE: A micro type X-ray tube is provided to improve the output of an X-ray by using a carbon nanotube electric field emission source part which is formed in the flat side of a metal wire. CONSTITUTION: An electronic gun part comprises a cathode electrode, a gate electrode, and an X-ray generation part. A carbon nanotube electronic beam source part is formed in the flat side of a metal wire. The gate electrode(2) is installed to be separated from the cathode electrode. The gate electrode is formed in a direction which is opposite to the cathode electrode. The X-ray generation part(5) is arranged to be separated from the gate electrode. An electric field control electrode is installed in the front side of a getter target.
