Design of the readout electronics system with high event rate based on the Micromegas Detector

Abstract

This paper presents a multi-channel readout electronic system with a high event rate. Its primary purpose is to meet the increasing collision luminosity in large particle physics collision experiments in recent years, thus bringing about the requirement of high event rates for readout electronics systems. This system is designed for Micromegas detectors and consists of front-end readout boards (FEB) and a data acquisition board (DAQ). It realizes that at 128 channels simultaneous readout, each channel can work at the maximum 2.2 Mhits/s event rate. Each event data contains amplitude and time information, which is read out by FEB. The event data will be sent to DAQ by the GTX transceiver at 3.2 Gbps and then transferred to the data acquisition software. In the data acquisition software, each particle hit position and track will be analyzed and reconstructed. The specific characteristics and implementations of this readout electronic system are described in detail.
