Abstract

A PXI-compatible amplifier and preamplifier module for the ⁵⁷Fe Mössbauer spectroscopy is presented in this paper. This PXI-compatible amplifier and preamplifier 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 Palacký University Olomouc. The module is based on the Amptek A225 and A206 integrated circuits. This solution allows miniaturization of the spectrometric system, as the amplifier and the preamplifier 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. This study deals with a comparison of the developed PXI-compatible amplifier and preamplifier board with the Amptek PC25 board in the stand-alone box (powered by a laboratory power supply), and with the ORTEC commercially available amplifier (572A) and preamplifier (142PC). The focus of this study is a comparison of those setups considering the false detections, lost detections, the multichannel analysis spectra, the Mössbauer spectrum quality, and the resonance effect of Mössbauer spectra.

与 PXI 兼容的莫斯鲍尔光谱比例气体计数器前置放大器和放大器

摘要本文介绍了用于 57Fe 莫斯鲍尔光谱分析的 PXI 兼容放大器和前置放大器模块。该 PXI 兼容放大器和前置放大器的开发目的是与对 14.4 keV 低能量伽马射线敏感的比例气体计数器配合使用，作为奥洛穆茨帕拉茨基大学开发的基于 PXI 的光谱仪的一部分。该模块基于 Amptek A225 和 A206 集成电路。由于放大器和前置放大器采用一个 PXI 模块的形式，并内置在紧凑的 PXI 机箱中，因此该解决方案可实现光谱系统的小型化。此外，由于开发的模块由 PXI 机箱中的 PXI 连接器供电，因此无需额外的电源。本研究比较了所开发的 PXI 兼容放大器和前置放大器板与独立机箱中的 Amptek PC25 板（由实验室电源供电），以及 ORTEC 市售放大器（572A）和前置放大器（142PC）。本研究的重点是对这些设置进行比较，其中考虑了误检、漏检、多通道分析光谱、莫斯鲍尔光谱质量以及莫斯鲍尔光谱的共振效应。
