Gas Chamber

A two-dimensional microstrip gas chamber (MSGC) with a 5 cm × 5 cm detection area has been developed. It has 254 anodes and 255 back strips, both with 200 µm pitches. Using this MSGC, linear polarization of X-rays was successfully measured in the energy range 6–14 keV. In addition, the performance of the MSGC as an X-ray imaging polarimeter has been simulated using the EGS4 program (Electron Gamma Shower, Version 4) modified for this purpose. In this article, the results of both the polarization measurement and the simulation are reported.

Linearly Polarized

The capabilities of an Si(511) channel-cut monochromator used with an X-ray tube with copper anode are presented. By passing this Si(511) channel-cut crystal, X-rays become both monochromatic and linearly polarized. The monochromaticity of the resulting beam is proved by angular dispersive measurements. Elastic scattering was used to characterize the degree of linear polarization.
