Using a commercial mini-X-ray source for calibrating Bragg crystals
Research output: Contribution to journal › Article
In this paper we describe a procedure for calibration of Bragg crystals used for X-ray spectroscopy of laser plasmas. The method uses a relatively inexpensive commercially available X-ray source. By using the source to pump a metallic foil such as vanadium or titanium we were able to create a K-α emission source with minimal background radiation outside the desired photon energy. By using photon counting techniques with a CCD detector we were able to get absolute calibrations of curved and flat Bragg crystals in the 4-5 keV region. An important advantage of our method is that absolute calibration was not necessary either for the commercial source or the detector.
