Characterization of a picosecond laser generated 4.5 keV Ti K -alpha source for pulsed radiography
Review of Scientific Instruments 76:7 (2005)
Abstract:
Kα radiation generated by interaction of an ultrashort (1 ps) laser with thin (25 μm) Ti foils at high intensity (2× 1016 W cm2) is analyzed using data from a spherical Bragg crystal imager and a single hit charge-coupled device spectrometer together with Monte Carlo simulations of Kα brightness. Laser to Kα and electron conversion efficiencies have been determined. We have also measured an effective crystal reflectivity of 3.75±2%. Comparison of imager data with data from the relatively broadband single hit spectrometer has revealed a reduction in crystal collection efficiency for high Kα yield. This is attributed to a shift in the K -shell spectrum due to Ti ionization. © 2005 American Institute of Physics.Modeling X-Ray Photoionized Plasmas Produced at the Sandia Z-Facility
