The acquisition of a single Silicon Photomultiplier require multiple and expensive electronics modules as : preamplifier, discriminator, bias voltage power supply, temperature monitor, Scalers, Analog to Digital Converter and Time to Digital Converter . The developed ArduSiPM is a compact cost effective and easily replicable Hardware software module for SiPM detector readout. The ArduSiPM uses an Arduino DUE (an open Software/Hardware board based on an ARM Cortex-M3 microcontroller) as processor board and a piggyback custom designed board (Shield), these are controlled by custom developed software and interface. The Shield contains different electronics features both to monitor, to set and to acquire the SiPM signals using the microcontroller board. The shield embed a controlled bias voltage power supply, a fast voltage preamplifier, a programmable fast discriminator to generate over threshold digital pulse , a peak hold to measure the pulse height, a temperature monitor system, a scaler to monitor over threshold rate and arrival time of the pulses. A TCP/IP Wi-Fi or Ethernet connection is used both to control and to acquire the ArduSiPM remotely with either a PC software or a Tablet APP (depending on the application).

PETALO read-out: A novel approach for data acquisition systems in PET applications
PETALO(a Positron Emission Tof Apparatus based on Liquid XenOn)是一种基于液体氙的正电子发射断层成像新方法。PETALO探测器的目的是利用其均匀的响应和连续性来捕获由闪烁产生的光。与其他PET探测器相比,该策略将导致无几何失真行为。为此,选择用于光读出的传感器是SiPM,其提供大面积、高增益和非常低的噪声。为了利用PETALO探测器的独特特性,读出架构必须设计为满足以下规格:与探测器相关的电子设备(前端和读出本身)必须在探测器尺寸方面完全可扩展。读出方案必须与探测器的非分段结构兼容。飞行时间(TOF)的能力必须在扫描器级别得到保证,也就是说,前端和读出电子设备不应降低LIFE时间性能。在这些程序中,引入了一种新的读出概念,它与PETALO等完全连续的介质探测器兼容。结果表明,该系统是可行的,与快速压缩技术的引入,以进一步降低数据带宽的要求。
