A method to clear plastic mines together with an apparatus to use it, is described in order to get an efficient, fast, cheap and reliable civil clearance of explosive devices, especially land mines and antipersonnel mines. The method consists of emitting focused high-power microwaves and radiating the minefield, or the location of a mine. To locate the hidden mines, the minefield is irradiated by low-power radiation and the back-radiation is received in the microwave and/or the infrared spectrum. Then specific concentrated high-power microwave radiation is used to burn down the mine. We suggest to generate the high-power microwave radiation with a gyrotron oscillator. It consists of an electron gun (1) forcing electrons within a resonator cavity (2) into spiral orbits by magnets (3). The so generated coherent microwave radiation (6) leaves the gyrotron through a microwave transmission window (4) and will be reflected and focused afterwards by quasi-optical reflectors (5) and (5').
