AbstractThis work presents the design, implementation and measurements of a complete electronic front-end intended for high-resolution spatial detection of ion beams at counting rates higher than 10^6 particles per second. The readout system is made up of three main multi-channel building blocks, namely: a transimpedance preamplifier, a signal-conditioning line receiver and a charge-to-digital converter, as well as some off-the-shelf components. The preamplifier and the line receiver have been specifically designed and optimized to minimize the overlapping probability of ion beams tracking, at high counting rates, in low-pressure gaseous secondary electron detectors. Experimental results are shown, considering alpha particles sources and particles beams, featuring an adaptive shaping time frame of 170-to-230 ns with a peak signal-to-noise ratio of up to 25 dB. These performance metrics are competitive with the state of the art, demonstrating the suitability of the reported data acquisition and instrumentation system for precise and fast particle tracking detection.
