Abstract

The invention discloses a particle injection system and an annular particle accelerator. The particle injection system adopts jumping magnet to provide a pulse magnetic field having a preset cycle to an injection beam, and the jumping of the transmission speed and the transmission direction of the injection beam occur, when the injection beam passes through the incident gap of the jumping magnet, and the jumping of the emittance phase ellipse of the injection beam occurs, and therefore the emittance phase ellipse of the injection beam falls into the acceptability phase ellipse of the annular particle accelerator, and the injection process of the injection beam is completed. The ratio between pulse width of the pulse magnetic field provided by the jumping magnet and the circling cycle of the storage beam of the particle accelerator is smaller than a set value, and therefore the injection beam can be captured by the radio frequency acceleration electric field of the annular particle accelerator after entering the annular particle accelerator with help of a horizontal oscillation amplitude damping oscillation attenuation process. Because the pulse width of the pulse magnetic field is small, disturbances on the storage beam of the annular particle accelerator cannot be caused by the pulse magnetic field.

Description

technical field

[0001] The present application relates to the technical field of accelerator physics, and more specifically, to a particle injection system and a circular particle accelerator. Background technique

[0002] The circular particle accelerator is not only one of the important equipment for exploring particle physics, but also one of the important equipment for modern advanced light sources. The process of injecting particles into the circular particle accelerator is also an important stage of the circular particle accelerator. The process of injecting particles into the annular particle accelerator in the prior art is mostly the process of moving the acceptance phase ellipse of the annular particle accelerator by combining impact magnets or convex rail magnets, so that the acceptance phase ellipse covers the injection beam emission phase ellipse, Commonly known as convex rail injection process, the specific process refers to Figure 1(a), Figure 1(b), Figure 1(c)...
