Design of the magnets for the HEPS injector

Abstract

Purpose

The high energy photon source (HEPS) is a diffraction-limited storage ring light source being built in Beijing, China. The HEPS accelerators consist of the storage ring and its injector which includes the linac, booster and beam transport lines. The magnet system is one of the most important systems for the accelerators. In this paper, the field design, mechanical design and some special issues of the main magnets for the injector are presented.

Methods

The magnets for the linac and transport lines work at DC mode, whereas the magnets for the booster work at dynamic mode. So the module of OPERA/TOSCA is used to design the DC magnetic field and the module of OPERA/ELLEKTRA is used to design the dynamic magnetic field. The CAD programs are used to design the mechanical structures of the magnets.

Results

The magnetic field simulation results of all the magnets for the injector can meet the physical requirements, the mechanical designs of all magnets are reasonable, and engineering drawings of the magnets for production are finished.

Conclusions

Both the magnetic field design and mechanical design of all magnets are satisfied with the physical requirements of the HEPS injector; the production of all magnets has been started up.
