Design and measurements of a preamplifier for particles tracking in secondary electrons detectors

This paper presents a preamplifier design and experimental characterisation to be used in the Front-End Electronic (FEE) requiered for spatial resolution measurements in low-pressure gaseous Secondary Electrons Detectors (Se D). The circuit - implemented in a Printed Circuit Board (PCB) as a probe of concept - achieves a transimpedance of 80dB, a DC-gain of 18dB, a Signal-to-Noise Ratio (SNR) of 36dB and a chaping time of 140-170ns. These characteristics allow us to minimise the overlapping probability in tracking detection for Radioactive Ion Beams (RIB) with a counting rate higher than 10(6) particles per second.Peer Reviewe
