Abstract :
In general, mechanical systems for particle accelerators are designed to remain stationary after they have been aligned. At the Advanced Photon Source (APS), a new device has been developed for the low-energy undulator test line (LEUTL), an experimental free-electron laser, that allows the components to be easily installed, removed, or exchanged without additional survey or alignment. A pair of high-precision linear guide rails fastened to a welded aluminum box beam provides the structure for this versatile and innovative method. The precision of this system exceeds ±380 μm along the beam axis and transverse to the beam. Design details and analysis are described as well as the present capabilities and those planned for the future
