  • Electron accelerator and radiotherapy apparatus using same
    Patent number: 7190764
    Abstract: A small and light-weighted electron accelerator (2, 40, 60) using a fixed-field alternating gradient of high electron beam intensity is provided with a vacuum container (10), an electric magnet (20) provided in the vacuum container, an electron beam inputting part (11) to input electron beam into the vacuum container (10), an accelerating apparatus (13) to accelerate electron beam, and an electron beam transporting part (26) to transport the accelerated electron beam from the vacuum container (10), and the electric magnet (20) is either an alternating gradient electric magnet made up with a converging electric magnet (21) and divergent electric magnets (22) provided at its both sides, or an alternating gradient electric magnet made up with a converging electric magnet (21) and divergent parts provided at its both sides, and an internal target (25) to generate X-ray is provided inside the vacuum container (10) right before the electron beam transporting part (26), and the accelerated electron beam and X-ray ar
