Alignment Design and Status of Taiwan Photon Source

Abstract

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 concerned by the change of temperature critically. In this paper, the whole process of alignment work in the TPS storage ring with the relation of survey network and thermal issues of the environment will be described. We analysed these survey data so that the correction of survey network could be estimated by the change of temperature, thus all the elements for example, booster, pedestals, and girders could be positioned within the shortest time.
