Abstract
A two-dimensional microstrip gas chamber (MSGC) with a 5 cm x 5 cm det ection area has been developed. It has 254 anodes and 255 back strips, both with 200 mu m pitches. Using this MSGC, linear polarization of X -rays was successfully measured in the energy range 6-14 keV. In addit ion, the performance of the MSGC as an X-ray imaging polarimeter has b een 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.
