摘要
A simple design and easily installed tool for alignment has been developed for time-sharing undulator beamlines. A laser beam is directed onto a beam splitter inside the vacuum chamber, then reflects 90 degrees along the synchrotron beam path; this beam serves as a reference to mimic the synchrotron beam path. Use of this tool greatly abbreviated alignment of an end-station after beamline switching; both beamline diagnosis and end-station development can be completed before the synchrotron beam time begins.
