Measurement of Nanosecond Pulse Based on Time-of-Flight

LIU Chuanjun1,2,REN Qiongying2(1.Graduate School,Chinese Academy of Sciences,Beijing,100080,China;2.Center for Space Science and Applied Research,Chinese Academy of Sciences,Beijing,100080,China)  
To better explore the space plasma composition,measurement system of nanosecond time interval based on the time-of-flight is studied.The main module for CPU,time interval measurement and data transmission in this system are introduced in this paper.The measurement method of nanosecond time interval,the chip of TDC-GP1 are intraduced in a detail.The firmware and drivers of data transmission module are given as well.The result of experiment show that the measurement system could meet the demands for space exploration.
