POLAR探测器是一种基于空间的伽玛射线暴（GRB）偏振计，具有宽视场，几乎覆盖了半边天。该仪器使用康普顿散射的伽马射线在一个塑料闪烁反射镜来测量入射光子的偏振。该仪器已于2016年9月15日在中国空间实验室天宫2号上成功发射。本文介绍了仪器部件的结构。详细介绍了在施工阶段遇到的问题及其解决方案。仪器在轨道上的初步性能符合地面试验和蒙特卡罗模拟的预期。(C) 2017 Elsevier B.V.版权所有
The POLAR detector is a space based Gamma Ray Burst (GRB) polarimeter with a wide field of view, which covers almost half the sky. The instrument uses Compton scattering of gamma rays on a plastic scintillator hodoscope to measure the polarization of the incoming photons. The instrument has been successfully launched on board of the Chinese space laboratory Tiangong 2 on September 15, 2016. The construction of the instrument components is described in this article. Details are provided on problems encountered during the construction phase and their solutions. Initial performance of the instrument in orbit is as expected from ground tests and Monte Carlo simulation. (C) 2017 Elsevier B.V. All rights reserved.
