摘要：

An asymmetric wiggler for the production of intense circularly polarized X-rays has been designed and tested successfully at HASYLAB. The device has ten periods and a period length of 240 mm. The magnetic design, device parameters and the results of magnetic field measurements are described. In order to characterize the circular polarization of the emitted light, the results of an experiment using this device for spin-dependent photoabsorption at the Gd and Pt L3 edges in Gd metal and in an PtFe alloy are presented. © 1990.
