| Research Abstract |
A detector system for position determination of gamma-ray bursts aboard the very small satellite for gamma-ray polarimetry was developed. The detector consists of CsI scintillator coupled with avalanche photodiodes, which enabled a lower detectable energy of 30 keV even at a room temperature. To evaluate the performance of the system on orbit we ran ray-trace simulation reflecting the whole geometry of the satellite, and confirmed that our detector system can determine the position of GRBs within a tolerance of 5 degrees.
