The transfer line design for the HEPS project

Abstract

Purpose

The high energy photon source (HEPS), a 6-GeV synchrotron radiation facility with ultralow emittance, is under construction in China. Three transfer lines are designed for HEPS. One low-energy transfer line is used to deliver the 500 MeV beam provided by the linac to the booster. Two high-energy transfer lines are used to connect the booster and the storage ring to realize beam accumulation in the booster at 6 GeV.

Method

The design of the transfer lines is closely related to the layout and optics design of the storage ring, booster and linac. Based on the physics design of the storage ring, booster and linac, the design of the transfer lines has been adjusted.

Results and conclusion

In this paper, the considerations and design of the latest lattice of transfer lines are described. The design satisfies the requirements of the high efficiency transmission and injection.
