Abstract :
Slow orbit movement in the horizontal and vertical planes at the Pohang Light Source (PLS) storage ring is analysed with the accumulated data of BPM and environment variables such as the ambient temperature of the storage ring tunnel, the LCW temperature, the outside weather condition, and the tunnel floor elevation. Each factor causes an orbit variation with different pattern and magnitude in the horizontal and/or vertical planes. Facts and causes of slow orbit movement are described as well as the orbit feedback in use or under preparation
