Monte Carlo simulation of the response functions of CdTe detectors to be applied in x-ray spectroscopy

Direct measurement of clinical mammographic x-ray spectra using a CdTe spectrometer

“…The measured spectra were corrected for the detector efficiency, Compton distortion and fluorescent escape fraction using a stripping procedure . The determination of the Compton efficiency was described by Terini et al The detector efficiency and fluorescent escape fraction were obtained by Monte Carlo simulations . Additionally, an area correction factor was applied to the set of spectra that were compared with the ones predicted by MASMIP and TASMICS models.…”

Caracterização de feixes de TC utilizando Espectrometria Compton

“…O espectro medido, calibrado em energia, era corrigido quanto à variação da eficiência do detector, escape de fotoelétrons e absorção nos materiais entre fonte e detector 8 .…”

Application of a semi-empirical model for the evaluation of transmission properties of barite mortar

“…This procedure takes into account the K-escape, Compton scattering and detector efficiency corrections. The efficiency curve and K-escape fractions were simulated (Tomal et al, 2014) using PENELOPE code (Salvat et al, 2003), while the Compton scattering fraction was estimated (Terini et al, 1999) using the cross sections from XCOM database Measurements of air kerma were performed simultaneously along with the X-ray spectra in order to be used as a normalization factor. It was taken into consideration that the area of the corrected spectra is numerically equal to air kerma value obtained with the ion chamber measurements (mGy).…”
