Hard x-ray polarimetry with a thick CdTe position sensitive spectrometer

摘要: Even though it is recognized that the study of polarization from cosmic high-energy sources can give very important information about nature emission mechanism, to date few measurements have been attempted. For several years we proposed use a thick CdTe array as position sensitive spectrometer for hard X- and soft gamma-ray astronomy, design which also efficient polarimeter at energies above approximately 100 keV. Herein describe preliminary results our based on 4096 microcrystals would like develop high altitude balloon experiment. We present telescope concept with description each subsystem together some activities devoted optimization detector units' response. Furthermore an evaluation performance in terms achievable spectroscopic polarimetric performance. In particular will show Monte Carlo simulations developed evaluate efficiency X ray polarimeter.
