“…The Ag L-shell characteristic x-rays are located at a relatively low energy region around 3.0 keV. However, there are few low energy points of several keV x-rays from radioactive standard sources, so we used the thick target bremsstrahlung spectrum by electron impact for the low energy efficiency calibration of the Si(Li) detector [38,[46][47][48][49]. The efficiency calibration of our Si(Li) detector in the low energy region has been carried out by measuring the 19 keV electron impact thick carbon target bremsstrahlung spectrum [49].…”

Au L α and L β and Ag L-shell x-ray production cross-sections by electron impact have been measured in the incident energy region from near threshold to about 25 keV. Thin films with thick aluminium substrates were used as targets in the experiments. The effect of directional and energy spreading of the electron beam within the active films and x-ray enhancement due to backscattering electrons and bremsstrahlung photons from the substrates are corrected by means of Monte Carlo simulations. The corrected experimental data provided by this method are compared with calculated cross-sections from a PWBA theory with Coulomb, relativistic and exchange corrections and with other experimental data available in the literature.

We studied the full-energy peak efficiency of a Si drift detector (SDD) and a Si (Li) detector (SLD) using the formalisms proposed by Seltzer [Nucl. Instrum. Meth. 188 (1981) 133] and O'Meara and Campbell [X-Ray Spectrom. 33 (2004) 146]. The respective adjustable parameters were fitted to full-energy peak efficiencies measured with certified point radioactive sources. Seltzer's model was able to reproduce the experimental data for the SDD and the SLD in the 6-40 keV and 6-100 keV energy ranges, respectively. In turn, O'Meara and Campbell's formula also performed well for the SDD between 6 and 40 keV and proved to fit satisfactorily in the energy interval 6-60 keV for the SLD.

The efficiency of a Ge(In) semiconductor x-ray detector was measured in the energy region 1-25 keV using proton-induced x-rays from thick targets and from thin targets of standard thickness, and the results of the two calibration methods were compared. A proton energy of 2.00 MeV was used in an external beam facility. A model based on fundamental parameters (mass absorption coefficients, fluorescence yields and relative x-ray emission rates) was used to reproduce the experimental results.
