Abstract

The invention provides a jumping magnet, which comprises a metal box (101) and a second metal plate (103). The cross section of the metal box (101) is a U-shaped structure. The opening of the U-shapedstructure is sealed by a first metal plate (102) with area larger than the bottom area of the U-shaped structure, so that an inner chamber is formed inside the metal box (101). A gap (104) is arranged on a central axis of the first metal plate (102), and the gap (104) is used for the incidence of a charged particle beam and used as a transverse channel of the charged particle beam. The second metal plate (103) is arranged in parallel with the first metal plate (102). The opposite sides of the first metal plate (102) and the second metal plate (103) have the same structure. The first metal plate (102) and the second metal plate (103) form an outer chamber. The jumping magnet can form an effective pulse magnetic field up to hundreds of Gauss meters, which is enough to meet the jumping demand of electrons and positrons with energy below 3.5GeV at a track slope change of 1mrad.

Description

technical field [0001] The present disclosure relates to the technical field of circular accelerators, in particular to a jumping magnet. Background technique [0002] The goal of the injection process of the charged particle circular accelerator is to store a higher flow intensity. During the working process, the local convex rail shrinks so that the subsequent damping process will send the incident beam to the acceptance space of the ideal closed rail. Due to the influence of the circular accelerator's nonlinear magnetic field, the transverse kinetic apertures of charged particle circular accelerators often have different scales. When the dynamic aperture is large enough, especially larger than the physical aperture of the charged particle circular accelerator, the injection process of the incident beam will be relatively smooth. With the development of circular accelerators, such as the high-brightness operation of storage rings, their dynamic apertures gradually become ...
