Abstract

The use of charge-coupled devices (CCDs) as single photon X-ray detectors has been documented by several research groups. In this paper we describe the design and performance of a powerful laboratory instrument for imaging and non-dispersive spectroscopy of soft X-rays (200 eV to 10 keV) utilizing Texas Instruments TI-4849 virtual-phase CCDs. With this instrument we have achieved a spatial resolution of 22 microns (limited by pixel size) with an overall array area of 584x390 pixels.We have achieved an energy-resolution of -140 eV FWHM for single-pixel Fe55 X-ray events (5.9 keV) with the CCD operated at only -30°C. We have operated the CCD in photon-counting mode at room-temperature and have obtained X-ray spectra with an energy resolution of -450 eV at 5.9 keV. We also have demonstrated the low-energy X-ray sensitivity of the CCD by detecting Carbon K-alpha X-rays (277 eV).
