Description

The data transfer interface of the Front End Electronics (FEE) is designed in for the Water Cherenkov Detector Array (WCDA) in Large High Altitude Air Shower Observatory (LHAASO). To meet the requirement of high-speed data transfer over many front end nodes scattered in a large area, a data transfer interface is specially designed based on the TCP/IP protocol and 1000 M ethernet, which is implemented using the embedded system in an FPGA device. Test results in the laboratory indicate that a data transfer rate more than 237 Mbps is achieved, beyond the application requirement. We also conducted 24-hour tests to evaluate the stability of the data transfer speed, also with good results as expected. (authors)
