Abstract: A detector system for capturing and resolving WAXS and SAXS beams is provided along with a device for determining structural information of a material incorporating said detector system and a method for examining the structure of a material using said detector system. The detector system generally comprises a sample capable of interacting with the incident x-ray beam, a primary detector and a secondary detector. Upon interaction with a sample of the material, the incident x-ray beam is scattered into wide angle x-ray scattering (WAXS) beams and small angle x-ray scattering (SAXS) beams that are captured by the primary or secondary detectors.

Abstract: The system includes a conductive window, a spectrum changing layer, a fiber optic bundle, a camera sensor, and a power supply. The spectrum changing layer is excited by the x-rays and emits a different wavelength of light, such as visible light. The fiber optic bundle receives the visible light from the spectrum changing material and transmits the visible light to the camera sensor. The camera sensor detects the light emitted from the spectrum changing layer and converts the information to electronic signals. The camera sensor is cooled by a cooling device, as such thermal conduction may cool the fiber optic bundle. To avoid condensation, current may flow through the conductive window thereby heating the conductive window.
