Abstract：
The double pulsed electron beams' characteristics such as the movement position, the beams spot and the emittance were experimentally studied in the time-resolved mode. In the experiments, beam bugs were usedto detect the beam currents and the beam positions, and the Cerenkov radiation generated by the electron beams interacting with a quartz plate was used to get the information of the beams. The radiation was recorded by an 8 film streak camera. The experimental results indicate that the double pulsed relativistic beams emission from velvet has almost the same centroid movement, the same beam spots and the same emittances. The vacuum diode voltages are 1.75MV and the beam currents are about 1kA.
