A variety of synchrotron radiation monitors has been developed to study the stability, size and emission angle of the source produced by bending magnets and insertion devices in the BESSY II storage ring. A new type of self-calibrating blade monitor called staggered pair monitor (SPM) installed in all bending magnet and wiggler front ends yields fast vertical position information with sub-micron precision. For undulator beams, results of position detection using 4-blade spectrometers capable of suppressing dipole radiation will be presented in combination with results of a mapping of undulator radiation using a high precision pinhole detector. Three optical monitors produce images of a cross section of the electron beam: a telescope based on Bragg-Fresnel optics and two pinhole array cameras to obtain size and emittance. © 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...
