摘要： There is provided a circular accelerator that accelerates a beam of charged particles circulating in a magnetic field such that a closed orbit for each energy of the beam is eccentric. The circular accelerator includes a beam extraction port for extracting beams of different energies from the closed orbit, a first bending magnet and a second bending magnet that bend the beam extracted from the beam extraction port, and a control unit that controls magnetic field strengths of the first bending magnet and the second bending magnet in accordance with the energy of the extracted beam. When the energy of the extracted beam is a designed maximum energy of the circular accelerator, the control unit excites both the first bending magnet and the second bending magnet to bend the beam.

摘要： The present invention is concerned with an electron beam intraoperative radiation therapy system using race-track microtron. In the preferred embodiment, the electron beam intraoperative radiation therapy system comprises a race-track microtron placed in a housing playing the role of the vacuum chamber, which is supported by a positioning means providing its motion with six degrees of freedom with respect to a patient. The positioning means is a part of a mobile mechanical structure which houses an ion pump, a microwave source, waveguide elements, a modulator with a pulse transformer and a cooler. The intraopearative radiation therapy system comprises a tube-like unit which couples the vacuum chamber with the mobile supporting mechanical structure and provides three functions, namely pumping out of the air from the vacuum chamber, feeding of the race-track microtron accelerating structure with radiofrequency power and rotation of the vacuum chamber with respect to the horizontal axis of the unit.

摘要： An electron beam and a positron beam are independently accelerated and accumulated up to a predetermined energy level, and are combined together (in a predetermined direction) to generate a beam of free positronium. This enables a monochromatic gamma ray having a maximum energy twice as great as the electron energy to be generated on the axis of the positronium beam, and further enables a monochromatic X-ray having a photon energy 1,3/100000 times that of the gamma ray to be generated as radiant light on the axis of the positronium beam.
