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： A new cavity which is separate from a rf (radio frequency) accelerating cavity is provided on the orbit of charged particles in a ring-shaped accelerator, and an external oscillator and a coupled antenna which serve to excite a rf electromagnetic field in the separate cavity are provided. Using the external oscillator and the coupled antenna, a deflection mode which has electric field components in the direction of the central orbit of the charged particles and in which a magnetic field in a direction perpendicular to the plane of the central orbit develops on the central orbit of the charged particles is excited in a beam duct part of the separate cavity through which the charged particles pass. The resonant frequency of the deflection mode is set at integral times that of a fundamental rf mode in the rf accelerating cavity, and the phase relationship between the rf fields of the rf accelerating cavity and the separate cavity is so held that, when the rf electric field intensity of the rf accelerating cavity has a phase of zero, the rf magnetic field intensity of the separate cavity rises in phase.

摘要： A wake field acceleator in which a current to be formed by a driving charged particle bunch that excites a wake field is controlled so as to compensate a Joule heat loss on the wall surface of a cavity constituting the wake field accelerator, and to subject the driving charged particle bunch to a substantially uniform deceleration voltage. With the wake field accelerator, the maximum transformer ratio can be realized with a small beam length of the driving charged particle bunch, and an energy extraction efficiency of approximately 100% can be realized.

摘要： An electron storage ring has bending magnets, quadrupole magnets, and sextupole magnets arranged in a ring for constraining a beam of electrons along a path. When the beam is injected, a control means controls a power source for the magnet so that the beam has a high equilibrium emittance. This gives the beam a large dynamic aperture, simplifying beam injection. Once the beam has been injected, the field strengths of the magnets are varied to cause a reduction in the emittance to a low value, at which the beam is stored. Synchrotron radiation is generated which has a high brightness because the low emittance means the beam has a small diameter. During the reduction in equilibrium emittance, the betatron oscillation frequency is maintained on a stable operation region and the chromaticity is maintained substantially zero.

摘要： In an electron storage ring comprising: a bending magnet for bending an electron beam; a focusing magnet for focusing the electron beam; a radio-frequency accelerating cavity for accelerating electrons; and a vacuum chamber, a voltage component fluctuating with time, e.g., sinusoidally is superposed on the power source of the focusing magnet, in case the electron beam is to be accelerated, to fluctuate the intensity of the focusing magnet. As a result, the number of the betatron oscillation of electron can be changed each time the electrons pass through the focusing magnet so that the damping rate can become higher than the growth rate of the instability of the beam to suppress the instability of the electron beam.

摘要： In an accelerator for accelerating charged particles by using electro-magnetic wave, in which a plurality of cells are disposed periodically, a washer-shaped electrode separated from the cylinder wall is located at the boundary of each of the cells, which electrode has a hole, through which accelerated charged particles pass, at its center portion and an approximately uniform thickness. The thickness and the diameter of said washer-shaped electrode and the gap between said washer-shaped electrode and the inner surface of said cylinder are so chosen that the average strength of the accelerating electric field is highest. The peak strengths of the electric field are approximately equal at the outer and inner peripheral portions of said washer-shaped electrode.
