摘要
为满足ALICE FoCal量能器升级中对高精度电荷读出和高速数据传输的需求,中国原子能科学研究院开展了基于现场可编程门阵列(FPGA)线性放电技术的高精度读出电子学研究。搭建了塑料闪烁体与SiPM耦合的测试平台,并开发了一套读出电子学原型系统。该系统采用放大器芯片配合表面贴装电容和电阻搭建模拟前端,并利用FPGA线性放电技术实现高精度电荷数字化,同时集成了多板同步、数据获取和数据压缩功能,能够满足FoCal中密集SiPM信号读取以及高速数据传输和处理需求。实验结果表明,该系统实现了1100 pC的动态范围和0.25 pC的电荷分辨率,能有效应对FoCal的挑战。
High-precision readout electronics based on field-programmable gate array(FPGA)linear discharge technology have been developed at the China Institute of Atomic Energy for the ALICE FoCal upgrade,which requires high-precision charge readout and high-speed data transmission.A test platform has been established with plastic scintillators coupled to Silicon photomultiplier tubes(SiPMs),and a prototype readout electronics system has been developed.The system used amplifier chips and surface-mount components for the analog front-end,and FPGA-based linear discharge technology for charge digitization.Additionally,the system incorporated multi-board synchronization,data acquisition,and compression functions,thus meeting the demands for dense SiPM signal reading,high-speed data transmission,and processing.Experimental results demonstrate the system’s capability to achieve a dynamic range of 1100 pC and a charge resolution of 0.25 pC,effectively addressing the challenges posed by FoCal.
