Abstract
An apparatus for simultaneously obtaining both non-dispersive and spatially-resolved soft x-ray spectra from a distributed soft x-ray source. A charge coupled device (CCD) camera having a back-illuminated CCD is irradiated by an x-ray source and a mechanical shutter or electronic shutter effect is used to define an integration period for the pixels of the CCD that ensures that the probability of a single pixel receiving more than one photon during the integration period is small. The magnitude of the charge at each pixel over an integration period is stored in a memory device and, after a plurality of integration periods have passed, the stored data for each pixel may be individually analyzed or combined and displayed to image the x-ray source.
