摘要：

The x-ray optics for a thin-crystal Si (400) Bragg transmission phase plate have been constructed for the production of 5 to 12 keV circularly polarized x rays. Using multiple beam diffraction from a GaAs crystal, a direct measurement of the degree of circular polarization as a function of off-Bragg position was made. These measurements indicated nearly complete circular polarization (|Pc|≥0.95) and full helicity reversal on opposite sides of the rocking curve. © 1995 American Institute of Physics.
