Description
As part of the RF2.0 project*, a permanent-magnet (PM) gradient dipole has been designed at MAX IV Laboratory to replicate the performance of a conventional electromagnet gradient dipole in Unit Cell-1 of the MAX IV 3.0 GeV storage ring. The new PM gradient dipole follows a modular design and utilizes NdFeB permanent-magnet blocks. The main advantage of this design is an expected reduction of up to 42% in the power consumption of the ring’s magnet system, assuming replacement of all dipoles. Moreover, the use of PMs enables a more compact dipole magnet, potentially freeing space within the existing Unit Cell footprints for the integration of higher-performance multipole magnets anticipated for the MAX 4U upgrade. This report summarizes the electromagnetic and mechanical design, installation planning, and the overall project status.
