Abstract
The present application provides a method for obtaining strong focusing of an isochronous accelerator by varying the magnetic field gradient in a large radial range. The method is characterized by the main magnet of the isochronous accelerator providing not only a bending effect but also a focusing effect, equivalent to the effects of quadrupole, sextupole, and octupole magnets used in a synchrotron accelerator.

A method for obtaining strong focusing of an isochronous accelerator by varying a magnetic field gradient in a large radial range, wherein a main magnet of the isochronous accelerator provides a bending effect and a focusing effect, which is equivalent to effects of using of quadrupole, sextupole, and octupole magnets in a synchrotron accelerator;
- the method comprises:
- introducing a first-order, a second-order, and a third-order magnetic field gradients in the large radial range of the main magnet of the isochronous accelerator to achieve an enhanced focusing, compensation of chromaticity, handling of resonances similar to that provided by a quadrupole, a sextupole, and octupole lenses, and obtain a transverse focusing force required for an isochronous continuous wave acceleration from 1 GeV to 2 GeV.
