Kd. Finkelstein et al., A MULTIPURPOSE POLARIMETER FOR X-RAY STUDIES, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 347(1-3), 1994, pp. 124-127
A compact polarimeter for the characterization of X-ray polarization h
as been built and tested. The device permits the measurement of linear
polarization by Bragg diffraction and the determination of circular p
olarization by means of multiple-beam diffraction [1]. This device is
small enough to be mounted on the two-theta arm of a 4-circle spectrom
eter so that the polarization properties of a beam emerging from an X-
ray experiment can be determined. We present several schematic views a
nd important details of the device design. In addition we present resu
lts obtained in using the polarimeter to characterize both the angular
distribution of synchrotron radiation at the CHESS F3 station and fro
m measurements of resonant diffraction in hematite (alpha-Fe2O3) near
the iron K-edge.
