Abstract

There are 46210 magnets in the CEPC Booster and Collider, of which the total length is about 160 km. So the magnets cost is a significant concern in the design of the magnets, particularly of the dipole magnets. In order to get the reasonable as well as economic schemes of the magnets for the Booster and Collider, some prototype magnets were developed and studied in TDR stage, some are designed and developed in EDR stage. In this paper, the design of the prototype magnets as well as an automatic magnet production line for the CEPC EDR are presented.
