International Workshop on Accelerator Alignment

After the construction of Taiwan Photon Source (TPS) was finished, the variation of the survey fiducials was stable. However, the following precise alignment work is influenced by the change of temperature critically. In this paper, we will describe the whole process of alignment work in the TPS storage ring with the relation of the survey network and the temperature of the environment. We analysed these survey data so that the correction of survey network could be estimated by the change of temperature, and all the elements of booster, pedestals, and girders could be positioned in the shortest time.
