Large bandwidth opamp-based preamplifier and shaping filter for smart rad-hard fast detection systems.
Castoldi A., Guazzoni C., Naggi A.
Different application fields require the development of fast preamplifiers and shaping filters to be coupled with dedicated radiation detectors. In view of fast prototyping and targeting a medium number of readout channels, we present the feasibility study, design and qualification of a large-bandwidth, opamp-based, preamplifier and shaping filter suited to equip a smart rad-hard detection system intended for the diagnostics and tagging of Radioactive Ion Beams (RIBs) at high intensity ({106 ${pps}$ or higher) The contribution illustrates the conception and design of the fast readout system and presents the detailed analysis and qualification of its performance in view of the design of a network of smart sensors, equipped with optimized frontend electronics, DAQ with Data Real-Time Management capabilities and a dedicated software layer implementing Artificial Intelligence and machine learning techniques as a tool to improve the production, transport and use of RIBs. Different prototypes have been produced and their performance experimentally compared in terms of noise, bandwidth, resolution,\,\ldots\,. both as a standalone circuit and coupled with a sample detector prototype.
