Abstract: 3.5MeV injector is the electron beam source of Dragon-I induction linac. Electron beam is extracted by the magnetic field from diode powered by an induction voltage adder, which is composed of pulsed power system, induction cavities, cathode/anode stem and radial insulator. Innovation is adopted in the development such as Pierce-like cathode, 800mm OD ferrite torroid and solenoids placed inside cathode/anode.Measurement shows that this injector is of high performance with output beam of 2.8kA,3.7MeV, and normalized emittance of 1040 p×mm·mrad, energy spread of 2.1%.
