<p>A solenoïd magnetic field generating part (5) is arranged along an electron beam (0) of an electron beam unit, and a high-frequency resonator (4) for inducing cyclotron maser is provided in this part (5). High-frequency waves for inducing cyclotron maser are projected from the high-frequency resonator (4) in the same direction as, or opposite to, the travelling direction of the electron beam (0) to adjust the emittance of the electron beam (0) and to generate a high-intensity beam. <IMAGE></p> |
