ABSTRACT
A new gap separation mechanism for use with the standard Advanced Photon Source (APS) 3.3-cm-period undulator magnetic structures has been designed and built, and the first system has been installed in the APS storage ring. The system allows a minimum magnetic gap of 10 mm for use with the APS 8-mm insertion device vacuum chambers. The mechanism is a bolted steel frame structure with a simple 4-motor mechanical drive train. The control system uses servomotors with incremental rotary encoders and virtual absolute linear encoders. © 2000 American Institute of Physics.

    The Advanced Photon Source (APS) is a third-generation synchrotron with major emphasis on insertion device (ID) sources. In the storage ring there are 35 straight sections, each about five meters in length, for possible insertion devices. Most of the insertion devices at the APS are 2.4 meters...

    A unique capability to vary the length of magnetic period in an undulator can be achieved with a geometry based on staggered arrays of permeable poles placed in a magnetic solenoid. The new classes of solenoid-derived undulators, which do not use permanent magnets, have the potential to provide...
