SiPM and PMT driving, signals count, and peak detection circuits, suitable for particle detection

摘要

The signals received from the optical receivers like SiPM and PMT due to the collision of energetic particles with the scintillators attached to these optical receivers are weak and fast. Optimizing signals is necessary to measure the number of signals and their peak height with electronic circuits. This text presents an example of SiPM's driver circuit, signal counting, and peak measurement. Also, the electronic circuits necessary to optimize the signals, including amplification, removing background noise, converting the signal to digital, and increasing the duration of the signal, are presented in this text. In the end, we provide two tests to confirm the correct operation of the circuits. Such a system has several advantages. This set has a small volume and is portable. Its operating voltage is 12 volts, with a current of about 0.3 amps; as a result, it is easily possible to use this set in any experiment. In addition, the cost of building such a system is much lower than providing similar ready-made designs. The most important achievement here is to convert the standard signal taken from the detector into an almost ideal optimized signal for signal counting and peak measurement. Therefore, it seems that using all or part of these circuits can be helpful for researchers. This text presents a particular method for signal optimization and provides the reader with a coherent and complete process of building and testing circuits. If the reader is familiar with the basics of electronics and detectors, they can reconstruct the circuits without any problems. Therefore, parts of this text may have an educational and review form.
