The extended-interaction oscillator with disk-loaded waveguide is presented as a new terahertz vacuum electronic radiation source. The device consists of an input cavity resonator with disk-loaded waveguide, a drift tube and an output cavity. A two and one half dimensional electromagnetic particle-in-cell simulation code is used to investigate it and the results demonstrate that the total length of the slow wave structure, the length of the drift tube and the radius of the output cavity affect the output power and frequency remarkably. It is found that under the condition of the electron beam with voltage 24.85 kV and current 20 mA, peak output power of 1.322 5 W at 755.5 GHz can be generated.
