Reflection enhanced gyrotron

The invention discloses a reflection enhanced gyrotron, and belongs to the technical field of millimeter wave devices. The reflection enhanced gyrotron is mainly characterized in that an electromagnetic wave reflector is arranged on the inner side or the outer side of an output window of the gyrotron so as to reflect part of electromagnetic waves output by the gyrotron back into the gyrotron body,that is, a feedback process is introduced, so that the beam-wave effect of the whole gyrotron in a working mode is enhanced, the requirement for overcoming mode competition is reduced, and the gyrotron can more easily achieve single-mode work in a specified mode. In addition, a special-shaped quasi-optical mode converter is further arranged, so that the peripheral electromagnetic beams deviate from the original direction and turn over in the gyrotron, and the beam-wave interaction is further enhanced. 本发明公开了一种反射增强型回旋管，属于毫米波器件技术领域，其主要通过在回旋管的输出窗内侧或外侧设置电磁波反射体，以将回旋管输出电磁波的一部分反射回到管体内部，即引入一个反馈过程，从而增强整个回旋管在工作模式下的束波作用，进而降低克服模
