Abstract

Using highly monochromatic X-ray synchrotron radiation ranging from 9 keV to 100 keV, accurate Lu₂Si₂O₇:Ce³⁺,Ca (LSO), Lu₃Al₅O:Pr³⁺ (LuAG), Lu₂Si₂O₅:Ce³⁺ (LPS) and Gd₂SiO₅:Ce³⁺ (GSO) nonproportional response curves were determined. By utilizing information from escape peaks in pulse height spectra the response curve can be extended down to several keV. A detailed study of the nonproportionality just above the if-edge is presented and from that a method, which we named K-dip spectroscopy, is obtained to reconstruct the electron response curve down to energies as low as 100 eV.
