Title:
APPARATUS PROVIDED WITH MULTIPLE TARGETS AND MULTI-ELECTRON BEAM FOR GENERATING X-RAYS
Document Type and Number:
WIPO Patent Application WO/2013/042810
Kind Code:
A1
Abstract:
The present invention provides an apparatus provided with multiple targets and a multi-electron beam for generating x-rays, which can simultaneously generate two or more characteristic x-rays, selectively generate a specific characteristic x-ray, or generate two or more specific characteristic x-rays in a sequence, thereby generating a variety of characteristic x-rays that are appropriate for a purpose, and which can generate a high-luminance characteristic x-ray for an extended period of time by increasing dissipation efficiency of heat that is generated at a rotary anode by means of a collision between an electron beam and the multiple targets. To this end, the present invention comprises: a case (100) provided with a vacuum chamber (120) therein so that the electron beam, which is emitted from a cathode filament (230), collides with and reflects off of the multiple target (330) of an anode; a cathode portion (200), which is provided on one side of the inside of the case (100) and is provided with a multi-filament cathode (230), which comprises a plurality of filaments (230a, 230b, 230c) for emitting the electron beam by being heated by a voltage that is applied; an anode portion (300) comprising the multiple targets (330), which include targets (330a, 330b, 330c) that comprise different elements and are separated away from each other in an axle direction along an outer circumference of a rotary anode cylindrical portion (310), so as to correspond to each of the plurality of filaments (230a, 230b, 230c); and a cooling portion (400) for dissipating heat, which is generated from the anode portion (300) when the electron beam collides, to the exterior of the case (100).
