Practical Filter & Simulative Controller Design for Radiation Signal Processing with Applications in Mossbauer Spectroscopy for Space Exploration

The miniaturised Mossbauer spectrometer II (MIMOS II) has proven to be a reliable measuring instrument for planetary exploration over many years. This paper presents a completely revised amplifier electronics in the radiation processing of Mossbauer spectroscopy and its optimisation. The overall electronics are divided into three parts, with this paper focussing exclusively on the first and second part of the signal chain for evaluating photons in experiments with gamma rays. The design makes it possible to weigh up the advantages and disadvantages compared to other simulated circuits in order to optimise MIMOS II for terrestrial and extraterrestrial measurements. First, the first two sections of the electronics are derived, analysed and then compared with measured values of the real circuit. The system behaviour results in a bandpass with cut-off frequencies between 10(1)Hz and 10(12)Hz, which is suitable for radiation measurements. Following the system analysis, a reduced state feedback with a realisable circuit geometry is developed to ensure implementation for real measurements.
