Electronic Circuit Design for Radiation Signal Processing with Applications in Mössbauer Spectroscopy for Space Exploration

The present work describes the further development of the transmission behaviour of the electronics in Mössbauer spectroscopy and its optimisation with regard to the use of predominantly commercially available electronic components. Due to the design developed here, the system order is reduced from $n_{\mathbf{pre}}=16$ to $n_{\mathbf{now}}=5$ and this simplifies the modelling. The overall electronics are divided into three parts, with this elaboration focussing exclusively on the first and second part of the signal chain for evaluating photons in experiments with gamma radiation. The design makes it possible to weigh up the advantages and disadvantages compared to other circuits in order to optimise MIMOS II for terrestrial and extraterrestrial measurements. The first two sections are derived, analysed and then compared with measured values of the real circuit. The system behaviour leads to a bandpass with cut-off frequencies between 10¹ Hz and 10⁷ Hz, which is suitable for radiation measurements.
