Patent attributes
An X-ray analysis apparatus comprises an X-ray source configured to irradiate a sample with an incident X-ray beam. A first beam mask component is arranged between the X-ray source and the sample. The first beam mask component has a first opening for limiting the size of the incident X-ray beam. When the first beam mask component is in a first configuration, the first opening is arranged in the incident X-ray beam. The first beam mask component further comprises a second opening. When the first beam mask component is in a second configuration, the second opening is arranged in the incident X-ray beam. The second opening does not limit the size of the incident X-ray beam. A controller is configured to control a first beam mask component actuator to change the configuration of the first beam mask component between the first configuration and the second configuration by moving the first beam mask component in a plane intersected by the incident X-ray beam.
