论文摘要
Caribou是一种灵活的开源DAQ系统，用于在几个协作框架（CERN EP R＆D，RD50，AIDAINNOVA）中，用于实验室和高速束测试，并易于整合新的Silicon-Pixel-Pixel检测器原型。它使用共享不同项目共享的常见硬件，固件和软件组件，从而大大降低了此类读取系统的开发工作和成本。 这项贡献引入了FastPix，APTS和DPTS探测器，该检测器最近集成在驯鹿及其在波形采样和数字脉冲时间方面的要求。开发了Caribou FPGA中实现的数字连接器，以克服先前使用的基于示波器的读数的局限性。它允许在fastpix和DPTS测试芯片中使用异步数字读数中使用的时间跨度，阈值时间和位置编码所需的大量时间跨度。校准后的时间分辨率大于10 ps。
Caribou is a flexible open-source DAQ system developed and used within several collaborative frameworks (CERN EP R&D, RD50, AIDAinnova) for laboratory and high-rate beam tests and easy integration of new silicon-pixel detector prototypes. It uses common hardware, firmware and software components that are shared across different projects, thereby reducing the development effort and cost for such readout systems significantly. This contribution introduces the FASTPIX, APTS and DPTS detectors recently integrated in Caribou and their requirements in terms of waveform sampling and timing of digital pulses. A Time-to-Digital-Converter implemented in the Caribou FPGA was developed to overcome the limitations of the previously used oscilloscope-based readout. It allows for precision timing over large time spans required for the Time-of-Arrival, Time-over-Threshold, and position encoding used in the FASTPIX and DPTS test chips with asynchronous digital readout. A time resolution after calibration of better than 10 ps is achieved.
