| Outline of Final Research Achievements |
Since 1960', many gamma-ray bursts have been observed with various observation methods. However, the radiation mechanism has been not clarified, yet. Recently, it is recognized by the observations of polarization for a few gamma ray bursts that the measurements of the polarization are useful for the clarification of the radiation mechanism. So we are developing larger polarimeter with higher sensitivity. It consists of multianode photomultiplier with ultra bialkali photocathode and GAGG scintillator and we have constructed the bread board model. From basic experiments and computer simulation, we recognized that it can obtain both 10% detection efficiency and 36% modulation factor even for 30 keV.
