Elliptical multipole wiggler for the production of variably polarized radiation
- Advanced Photon Source, Argonne National Laboratory, Argonne, Illinois 60439 (United States)
A new insertion device has been designed, manufactured, and tested as a result of a collaboration between the Advanced Photon Source, the Budker Institute of Nuclear Physics, and the National Synchrotron Light Source. The device{emdash}an elliptical multipole wiggler (EMW){emdash}is a source of variably polarized x-rays. It has a period of 16 cm and consists of two magnetic structures. The hybrid magnet structure produces a vertical wiggler field with a peak value of 8 kG. The horizontal wiggler field (1 kG) is generated by electric coils capable of operating with a switching frequency up to 100 Hz. After fabrication, the EMW was measured and magnetically tuned. When installed on the NSLS X-ray Ring, the EMW produces variably polarized radiation in the 1{endash}10 keV energy range. {copyright} {ital 1996 American Institute of Physics.}
