Appeal No. 2004-0612
Application No. 09/531,660
a sample table for fixing a sample to be radiated by
the primary X-ray;
a detector for detecting a secondary X-ray produced by
the sample in response to irradiation by the primary X-ray; and
a collimator mechanism removably insertable in an X-ray
path between the sample and the detector for passing a secondary
X-ray component having a uniform extraction angle and reducing a
secondary X-ray component having a non-uniform extraction angle,
the extraction angle being defined between a first line
connecting an intersection of a center line of an X-ray optical
flux radiated by the X-ray source with a plane of the sample
table and a second line connecting a center point of a detection
region of the detector with a plane of the sample table.
5. An X-ray analysis apparatus for analyzing a sample,
comprising: an X-ray source for radiating a primary X-ray onto
the sample; an X-ray detector for detecting a secondary X-ray
emanating from the sample in response to irradiation of the
primary X-ray onto the sample to produce an energy spectrum; and
a collimator interposed in a path of the secondary X-ray between
the sample and the X-ray detector for allowing a collimate
component of the secondary X-ray to pass therethrough.
