Abstract
Taiwan Photon Source (TPS) is a new 3-GeV ring under construction at NSRRC Taiwan with high brightness and low emittance characteristics. Due to the stability consideration, the whole building is constructed half underground, so the survey and alignment works are quite confined and difficult. For positioning magnets precisely and quickly, a high accuracy auto-tuning girders system...

The ongoing NSLS II project requires +/-30 micron alignment accuracy for the 6 or 7 mangets in each girder assembly. The vibrating wire technique used to alignment magnets in one girder can achieve a couple of micron precision. However, the tranportation and manner change of supporting will change the girder profile, hence the magnet alignment, to the extent of bigger than +/-50 micron.This...

To determine how well the modules of the NOvA far detector are aligned, a laser scanner measures the positions of points on the upstream side of each layer.
