Notes:
In December 1994, an elliptically polarized wiggler was installed in the X13 straight section of the NSLS X-ray Ring. This device generates circularly polarized photons in the energy range of 0.1–10 keV with AC modulation of polarization helicity. The vertical magnetic field is produced by a hybrid permanent magnet structure, and the horizontal magnetic field is generated by an electromagnet capable of operating with a switching frequency of up to 100 Hz. The elliptically polarized wiggler was commissioned during spring 1995 at an operating frequency of 2 Hz. Here, we discuss the compensation of the residual-orbit motion-utilizing trim coils at the wiggler ends and the high precision orbit measurement system of the X-Ray ring. © 1996 American Institute of Physics.
