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.
