Simulative Development of the Mössbauer Spectroscopy With Focus on the Transimpedance of the Photodiode Circuit -- Part I

Abstract In the context of planetary exploration, the MIMOS II (miniaturized Mössbauer spectrometer) serves as a proven and reliable measuring instrument [1]. The MIMOS II originally devised by Göstar Klingelhöfer, is further developed by the Renz group at the Leibniz University Hanover in cooperation with the Hanover University of Applied Sciences [1] [2]. In this context here, the transmission behavior of the initially simulated amplifier circuit is to be determined and can serve as a basis for a later control [3]. Here, the results, are collected of the the circuit version intended for practical tests. The electrical circuit used in this elaboration is a modified version of a photodiode amplifier [3] [4]. The amplifier combines and replaces the usually switched multiple filters and the signal pickup of the photodiode current and the design should help to weigh advantages and disadvantages against other simulated circuits in order to optimize the MIMOS II for the terestric and extraterestric measurment.
