Abstract

Abstract

Environment temperature is an important factor affecting the stability of electron beam orbit . Most accelerator laboratories of the world have built environment temperature monitoring systems and air-condition systems. HLS is a light source of the second generation, the shift of the global beam orbit is required to stabilize within 100 mm in vertical plane. An environment temperature monitoring system was built recently for analyzing the environment temperature influence on beam orbit. The structure of the system and the problem of radiation interference are described. The data analysis indicates that beam orbit fluctuation is strongly correlated to temperature variation and the beam orbit in vertical plane varies 10~20 mm when the environment temperature changes 1 ℃.
