  The prototype of TPS injection girder system was designed and installed in a temporary factory. As the leakage field of the kicker magnet in the prototype was found to be too large according to both simulation and measurement to be acceptable, the lattice was altered to fit the requirements. In this paper, we present the design modifications of the injection girder system due to the new lattice. The DC septum magnet is replaced by a pre-AC septum magnet, of which its adjustable stage must be redesigned. The positions of vacuum components in the injection girder are also altered; we add some new holes in the prototype girder. The prototype of an injection girder system after modification has been installed in the tunnel of Taiwan Photon Source. The accuracy of position of three girders installed, and the stages for the septum or kicker magnet are within 0.25 and 0.08 mm, respectively.

  Taiwan Photon Source (TPS) is a new 3-GeV ring under construction at NSRRC in Taiwan. There are hundreds of magnets placed on girders that must be aligned correctly to keep the electronic beam in the desire orbit. Due to the reasons of manpower, set up time, accuracy of adjustment, deformation of the floor, and limited space, an auto-alignment girder control system was designed to meet this requirement. The auto-alignment test was completed with one double-bend cell at NSRRC. The Auto-alignment process will be tested with some sections of magnet girders to confirm the control system and the algorithm in the TPS. The status and test results will be described in this paper.
