Funding: This material is based upon work supported by the U.S. Department of Energy, Office of Science, Office of Nuclear Physics under contract DE-AC05-06OR23177. JLEIC is the high luminosity and high polarization electron-ion collider (EIC) currently under design at Jefferson Lab. Its luminosity performance relies on the beam stability under high-intensity electron and ion beam operation. The impedance budget analysis and the estimations of beam instabilities are currently underway. In this paper, we present the update status of our back-of-envelope estimations for these collective instabilities, and identify area or parameter regimes where special attentions for instability mitigations are required. |

WEOBB05 | CEPC Collider and Booster Magnets | sextupole, quadrupole, booster, collider | 247 |

Funding: Work supported in part by the Yifang Wang scientific Studio of the Ten Thousand Talents Project. A Circular Electron Positron Collider (CEPC) with a circumference of about 100 km, a beam energy up to 120 GeV is proposed to be constructed in China. Most mag-nets for CEPC Booster and Collider ring are conventional magnets. The quantities of the magnets are large, so the cost and power consumption are two of the most im-portant issues for the magnet design and manufacturing. The dual aperture dipole and quadrupole magnet with low current high voltage are used in the collider ring. While in the booster the dipole magnet works at very low field, so a low packing factor dipole magnet or a coil type without iron design will be investigated and chosen. In this paper, the conceptual design of the CEPC main mag-nets are in detailed and the R&D plan is presented. |
