TI - Status of Interaction Region Magnets for CEPC J2 - Proc. of eeFACT2022, Frascati, Italy, 12-16 September 2022 CY - Frascati, Italy T2 - ICFA Advanced Beam Dynamics Workshop on High Luminosity Circular e+e- Colliders T3 - 65 LA - english AB - High gradient quadrupole magnets are required on both sides of the interaction points in the proposed Circular Electron Positron Collider (CEPC). There are three double aperture superconducting quadrupoles with a crossing angle between two aperture centerlines of 33 mrad. It is challenging to meet stringent design requirements, including limited space, magnetic field crosstalk between two apertures, magnetic field gradients up to 142 T/m, etc. In this paper, status of superconducting magnets in CEPC interaction region in the technical design stage is described. Magnetic design of superconducting quadrupole magnet with three kinds of quadrupole coil structures, including cos(2theta) coil, CCT coil, and Serpentine coil is presented and compared. In addition, the development status of a single aperture short model quadrupole magnet with a magnetic length of 0.5 m is presented.
