Abstract

At the Taiwan Light Source (TLS), the stability of the electron beam orbit is sensitive to the utility conditions. The beam position showed strong correlation with the temperature while the tunnel temperature variation was more than 0.4°C. In this work, the coolant temperature and the air temperature in the storage ring tunnel were tuned to test the sensitivity of the electron beam orbit. The temperature difference of the devices in the TLS might be as high as 10°C between the system shutdown and operation. These temperature variations affected the beam stability through some specific routes. Some modeling technique was also applied to identify the correlation factors among the beam position and the utility conditions
