Peniotron development activities at Research Institute of Electrical Communication, Tohoku University in Sendai are directed along three directions, auto-resonant peniotron oscillator (ARPO) with a high efficiency, the backward wave peniotron oscillator (BWPO) with a wide band frequency tunability and higher cyclotron harmonic peniotron oscillator for a high frequency generation. This paper will review the recent work performed in these three fields.
