Abstract
An X-ray analysis device makes use of a variable aperture for controlling the position and cross section of the X-ray beam. The variable aperture is configured to allow changes in the cross section and/or position of the beam by movement of one aperture component in one direction. In one embodiment, the aperture medium is a perforated disk that is rotated to expose different aperture holes to the beam. In another embodiment, the aperture medium is a perforated tape that is moved in a linear direction to expose different aperture holes to the beam. The tape may be wound about two axes to control its movement, or may be a continuous loop. A cassette may also be used to house the tape.
