PURPOSE:To generate an electromagnetic wave of the large power by constituting a resonance part while using an axially symmetrical partially transmissive mirror. CONSTITUTION:The electromagnetic wave of an electron beam 19 is oscillated and amplified by a partially transmissive mirror 22 for being transmittd in the direction of a mirror 23. The reflection face of the mirror 23 has an oval face 40 having two focal points, namely the center 37 of the partially transmissive mirror 22 and the center 39 of the reflection face 38 of a mirror 24. Similarly, the mirror 24 has two focal points, namely the center 41 of the mirror 23 and the center 43 of the reflection face 42 of the mirror 24, while the electromagnetic wave reflected on the reflection face 28 is reflected on the reflection face 42 for being transmitted in the direction of the mirror 25. Also the mirror 25 has the reflection faces 44 and 45 while transmitting the electromagnetic wave in the Z-direction and the reflection face 45 is formed into an oval rotary face for matching its focuss point on the plasma 46 to be an object of heating. Accordingly, the electromagnetic wave in the radial direction generating from the electron beam is made to resonate while being amplified covering the whole periphery for being efficiently transmitted in the direction of a heating target thus being able to obtain a device of the large power.
