EDXRF with an audio digitizer

Abstract: We utilized an audio digitizer in energy‐dispersive X‐ray fluorescence (EDXRF) with a silicon drift detector and achieved a full width at half maximum (FWHM) of 178 eV at Mn Kα (92‐µs peaking time). To confirm the ability of EDXRF with an audio digitizer, we also examined energy versus channel number linearity and output count rate. We applied it to EDXRF analysis of (ZnCd)S : Ag and showed a proper energy versus channel number linearity from 5.9 keV (Mn Kα) to 26.1 keV (Cd Kβ). And, the maximum output count r… Show more

“…During compression of the crystal sugar, an X‐ray detector system was set toward the through‐hole at the distance of 15 mm. The X‐ray detector system consisted of CdTe X‐ray and γ ‐ray detector (XR‐100T‐CdTe, Amptek Inc.) with an audio digitizer made by our laboratory . The calibration of X‐ray energy was performed by radium radioisotope.…”

“…The overall energy resolution of the spectrometer was in the range 130 to 150 eV for Zn-Ka peak. Nakaye and Kawai 21 demonstrated the capability of an ordinary audio digitiser applied as the ADC for digitising the signal from reset-type charge-sensitive silicon drift detector preamplifiers. The signal was subsequently fully software-processed in a PC to obtain the pulse-histogram in the form of an energy dispersive X-ray spectrum.…”
