Insertion device commissioning at SRC

The Synchrotron Radiation Center (SRC) has been installing undulators on its 1-GeV electron storage ring, Aladdin, over the last 15 years. Commissioning these devices is subject to fairly demanding requirements related to the needs of the user community. A number of topics are discussed, including injection, trim-control, steering correction, beam size stabilization, and lifetime preservation. Experiences, problems, and solutions are presented from both machine and beamline aspects.
