Abstract
The present invention is to provide a method and an apparatus which are able to inject a large amount of charged particles to a circular accelerator. In order to inject a large number of charged particles, the charged particle beams are injected into a region of a vacuum duct other than the region which is defined as having a height equivalent to the height of the injected beam and a width from the injected point in the vacuum duct to the symmetrical point to the injected point with respect to the geometrical center of the vacuum duct.
Claims16
A circular accelerator comprising:
- means for constituting a center closed orbit;
- means for injecting a beam of charged particles into the center closed orbit;
- means for accelerating said beam;
- and
- additional means, operative only during injection of said beam, for shifting an orbital path of said beam injected into the center closed orbit in a horizontal direction toward a side opposite to the injection side.
A method of injection of a beam of charged particles into a circular accelerator having means constituting a center closed orbit, comprising the steps of:
- injecting the beam of charged particles into the center closed orbit;
- accelerating the beam;
- and
- shifting an orbital path of the beam injected in the center closed orbit in a horizontal direction toward a side opposite to the injection side.
