【Abstract】 The large area scintillation detector system, which is designed for the cosmic γ ray burst observation to be carried on by our own satellite by the end of this century, is described briefly in this paper. It includes the technical design, selection of key components and structure materials, measures taken to ensure the system’s safety and reiability and protection of the detector when it passes the South Atlantic Anomaly (SAA) region. Especially, the primary experiment results by complementary method for higher energy resolution, space environment simulation as well as the electromasnetic compatibility (EMC) test are presented. The γ ray burst observation sensitivity using such system is evaluated based on these studies. (更多还原
