Simulation studies were carried out on newly designed compact 100 GHz range backward-wave oscillator (BWO) with an interdigital slow-wave circuit: teeth of two combs are facing each other. A steady radiation at a frequency 100 GHz with output power of 700 mW was observed. The output power is about five times larger than the present BWO with a same range. We have started the construction of proto-type BWO with 40 GHz and 100 GHz range. We designed and constructed the thermionic electron gun that produces an electron-beam running in a homogeneous magnetic field formed by Nd magnets with sufficient energy and emission current for the radiation.
