X-RAY TUBE HAVING A VACUUM EXHAUST STRUCTURE CONNECTED TO A VACUUM EXHAUST PATH, AN ANODE PART THEREOF, AND A MANUFACTURING METHOD OF THE ANODE PART FOR THE VACUUM EXHAUST OF THE -RAY TUBE

摘要

PURPOSE: An x-ray tube, an anode part thereof, and a manufacturing method of the anode part are provided to discharge internal gas by forming a vacuum exhaust path and a vacuum exhaust pipe.;CONSTITUTION: A cathode part comprises electron emitter which emits an electronic beam. A grid(160) has a cylinder structure. Vacuum exhaust paths(215,220) are formed in a body of the anode part. A vacuum exhaust pipe(230) is connected to the vacuum exhaust paths. The vacuum exhaust pipe makes the inner side of an x-ray tube vacuous.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Electron beam; (BB) X-ray
