摘要

In order to adjust the beam time structure and convert the continuous wave beam into a pulsed one,a server hardware system based on FPGA and W5300 Ethernet interface is designed,and the client interface running on PC is designed with the help of Visual Sdudio development platform.The pulse voltage output with adjustable delay,variable cycle and pulse width can be made at either single pulse mode or continuous pulse mode.In a long term test,the system worked reliably and stably,and the precision of output pulse time can reach 20 ns,which meets system requirements.
