Abstract：
The electron beam measurement system for Dragon-I must work synchronously with the beam production and transportation accurately in order to obtain correct data．The synchronization with about 1ns is important．The output waveform of Blumlein lines in pulsed-power system is of amplitude of about 250kV and 20ns active edge time(following edge)．The electron beam will hit the conversion target in about 145ns later steadily and the jitter time is about 1—2ns．The synchronization precision with the same level of the jitter time will be reached if the sharp following edge of waveform is selected to be the time base．The synchronization trigger signal for measurement system can be obtained by the way of differentiating the following edge and the accuracy of about ns can also be reached with suitable circuit parameters．The optical fiber is also adopted to remove the interference on the measurement system from the high voltage system．This kind of burst trigger mode overcomes many disadvantages such as low accuracy, long delay time, large jitter in normal trigger mode and can provide the trigger time accurately．It can meet the need to measure the electron beam parameters at any required time．
