PXI-Compatible Preamplifier and Amplifier for Proportional Gas Counters for Mössbauer Spectroscopy : [Abstract] / P.Kohout, A.Kohoutova, A.Opichal, [et al.] // Физика элементарных частиц и атомного ядра.

A PXI-compatible preamplifier and amplifier module for *5*7Fe Mossbauer spectroscopy is presented. It was developed for the purpose of utilization with proportional gas counters sensitive to the 14.4-keV low energy gamma rays as a part of PXI-based spectrometers developed at Palack´y University Olomouc. The module is based on the Amptek A225 and A206 integrated circuits. This solution allows miniaturization of the spectrometric system, as the preamplifier and the amplifier are in a form of one PXI module, which is built in the compact PXI chassis. There is also no need for an additional power supply, as the developed module is powered by the PXI connector included in the PXI chassis. The study deals with a comparison of the developed PXI-compatible amplifier and preamplifier board with the Amptek PC25 board in the standalone box (powered by a laboratory power supply), and with the ORTEC commercially available amplifier (572A) and preamplifier (142PC). The focus of the study is a comparison of those setups considering the false detections, lost detections, the multichannel analysis spectra, the M¨ossbauer spectrum quality, and the resonance effect of M¨ossbauer spectra.
