The Implementation of Data Acquisition and Summary Circuits Based on FPGA in Keda Torus eXperiment

An active control electronics system has been implemented for Keda Torus eXperiment (KTX). The printed circuit board (PCB) for active control follows a modular design based on PXI Express. Field-programmable gate array (FPGA) is the core component of the PCB. The scalable FPGA mezzanine card (FMC) standard is adopted. One FMC carrier card and two FMC mezzanine cards for data acquisition and summary transmission have been developed. This article introduces the selection of each chip and the functional design of the PCBs in detail. Results indicate that the PCBs can work normally.
