In the first phase, 15 front ends will be installed, including 14 ID front ends and 1 BM front end. These front ends are divided into three categories: the standard undulator front end, the wiggler front end, and the BM front end. The peak power density that the front end bears is about 868kW/mrad², the total power is about 47kW. This paper describes the general layout design of the three different types of front end, the functions of the main components, and the finite element analysis of key devices in the HEPS front end.
