摘要： When accelerating charged particles on synchrotron acceleration basis by using a circular accelerator having a RF acceleration cavity, the detuned amount representative of an offset between oscillation frequency of a RF oscillator for the RF acceleration cavity and resoance frequency of the RF acceleration cavity and the RF power for supplying the charged particles with energy are controlled in compliance with changes in energy of the charged particles without changing the oscillation frequency. A great number of charged particles injected into the circular accelerator can be accelerated to the ultimate storage energy during the acceleration on synchrotron acceleration basis without causing charged particle beam loss.

摘要： An acceleration device for charged particles has an acceleration cavity through which passes a beam of the particles. High frequency power from a suitable source is transmitted to the cavity via a suitable transmission means (antenna) to transmit the energy to the particles and so accelerate them. The transmission means is controlled by a suitable control to control the coupling constant of the transmission means when power is applied. Also, the device may have a looped conductor in the cavity controlled by the control to couple to the field in the cavity and to extract power from the field, thereby to control the de-tuning of the applied power relative to the power transmitted to the particles. By controlling the coupling constant and/or the de-tuning, power may be transmitted efficiently to the beam of particles.

摘要： A circular accelerator is arranged to circulate a charged particle beam through a bending function provided by a bending magnet, set a tune of the charged particle beam being circulated as it is betatron-oscillated to a predetermined value through the effect of a quadrupole magnetic field, resonate the charged particle beam being circulated at the tune set to the predetermined value in a manner to increase an amplitude of the betatron oscillations over the stability limit of resonance, thereby extracting the charged particle beam. The circular accelerator includes a bending magnet formed to generate a quadrupole magnetic field component for horizontally focusing the charged particle beam being circulated and vertically defocusing the beam and another bending magnet formed to generate a quadrupole magnetic field component for horizontally defocusing the charged particle beam being circulated and vertically focusing the beam. The accelerator is reduced in size, easily operated, and enables to keep the location of the beam extraction and the diameter of the beam constant and output an excellent charged particle beam.

摘要： A small-sized circular accelerator capable of generating radiation of high brightness, an operation method of the circular accelerator, and a semiconductor irradiation system capable of using radiation of high brightness. An electron beam emitted from a pre-accelerator is injected to the inside of the storage ring by an injector, and accelerated and stored. Thereafter, each of insertion devices respectively disposed in linear orbit sections between main bending magnets and auxiliary bending magnets are excited to generate an alternating field therein. A meandering or spiral movement of the electron beam is caused by this alternating field. By superposing radiations emitted from vertexes of the meandering orbit or the spiral orbit, radiation having high brightness is generated.
