Beam diagnostic beamlines at HEPS storage ring

High Energy Photon Source (HEPS) is a 6 GeV dif-fraction limited storage ring light source. An ultralow emittance of ~34 pm·rad is designed with a multiple-bend achromat lattice at storage ring. The transverse beam sizes at the dipoles will be less than 10 µm. In order to measure such small beam sizes in both directions, an X-ray beam diagnostic beamline is designed with bend-ing magnet as source point. X-ray pinhole imaging and KB mirror imaging are used compatibly and comparably to capture beam image. A visible light beam diagnostic beamline is designed to measure bunch length with streak camera. During the first phase storage ring commissioning time, both diagnostic beamlines captured the first light.
