A double pulsed beam generator is built based on 2MeV linear induction accelerator (LIA) injector. The second power source and 8 inductive cells of the injector are divided into two groups and work alternatively. Electron energy of each beam is up to 1MeV and the beam duration is 120ns with adjustable pulse interval (from 200ns to 800ns). The voltage amplitude difference of the two pulses can be less than 2%. The electron beams are emitted from a velvet cathode in a vacuum diode. The beam currents are up to 3kA, measured both by a Faraday cup in anode hole and by a shunt resistor at the rail of the LIA injector. This device can be used to study multi-pulse diode physics and emitting physics of different materials under multi-pulse mode.
