<p>A CHARGED-PARTICLE ACCELERATING DEVICE FOR METRIC-WAVE OPERATION The particle-accelerating device comprises a charged-particle source, a linear accelerating structure formed by a series of accelerating resonant cavities, an electromagnetic wave generator for emitting a signal to be injected into at least one of the resonant cavities. Means are provided for applying a pulsed high voltage to the particle source and for scanning a target with the pulsed beam of accelerated particles. The electromagnetic wave generator comprises a thermionic tube having a cathode, an anode and at least one grid. At least one of the resonant cavities is electromagnetically coupled to the grid-anode space of the tube.</p> |
