摘要:

美国宇航局费米伽马射线太空望远镜的科学目标之一是研究伽马射线暴(GRB)。费米伽马射线暴监测器(GBM)的设计目的是探测和定位费米任务的爆发。通过12个NaI(Tl)(8 keV至1 MeV)和两个BGO(0.2至40 MeV)闪烁探测器的阵列,GBM将费米的主要仪器大面积望远镜的能量范围(20 MeV至> 300 GeV)扩展到当前GRB数据库的传统范围。GBM仪器对伽玛暴的物理探测器响应是通过蒙特卡罗模拟确定的,该模拟得到了地面单个探测器校准测量的支持和验证。我们提出的主要仪器属性,已被确定为能量和角度的函数,包括通道能量关系,能量分辨率,有效面积和空间均匀性。

英文摘要:

One of the scientific objectives of NASA's Fermi Gamma-ray Space Telescope is the study of Gamma-Ray Bursts (GRBs). The Fermi Gamma-Ray Burst Monitor (GBM) was designed to detect and localize bursts for the Fermi mission. By means of an array of 12 NaI(Tl) (8 keV to 1 MeV) and two BGO (0.2 to 40 MeV) scintillation detectors, GBM extends the energy range (20 MeV to > 300 GeV) of Fermi's main instrument, the Large Area Telescope, into the traditional range of current GRB databases. The physical detector response of the GBM instrument to GRBs is determined with the help of Monte Carlo simulations, which are supported and verified by on-ground individual detector calibration measurements. We present the principal instrument properties, which have been determined as a function of energy and angle, including the channel-energy relation, the energy resolution, the effective area and the spatial homogeneity.
