“…The purpose of this paper is to review, adapt, and test existing procedures based on radioactive sources to SDDs and SLDs, accounting for their particularities. We will not delve into methods that rely on thick‐target bremsstrahlung, or synchrotron radiation,.…”

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.

“…[6], the accuracy of the detection efficiency determined by the whole MC simulations strongly depends on the accuracy of the geometry parameters of the X-ray detector. In this paper, a more reliable method was used to calibrate the low-energy detection efficiency of the X-ray detector as detailed elsewhere [8,[16][17][18]. In order to check others' work [3,4], here we applied the on-line monitoring technology developed by our group to measure the Ag L αβγ characteristic X-ray yields of thick targets impacted by positrons up to 9 keV.…”

In this paper, the on-line monitoring technology of the slow positron beam intensity has been applied to measure the Ag L αβγ characteristic X-ray yields with pure thick target by 6-9 keV positrons impact. The experimental characteristic X-ray yields have been compared with the corresponding yields simulated by Monte Carlo calculations, and the ratio of the former to the latter has been defined as the scaling factor. Then the experimentally scaled theoretical X-ray production cross-sections have also been acquired by multiplying the Ag L αβγ X-ray production cross-sections in the database of the Monte Carlo code used in this work by the corresponding scaling factor. Some discrepancies between the Distorted Wave Born Approximation (DWBA) predictions and the experimental data provided by different authors have been discussed. In order to analyse the accuracies of the published experimental data with the thick-target method in the literature, the contribution of the multiple scattering of incident positrons, from the bremsstrahlung and annihilation photons and other secondary particles to the characteristic X-ray yields has been estimated by means of the Monte Carlo simulation technique in combination with the theoretical integral calculation.
