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.

气体像元探测器(GPD)是为高灵敏度天文X射线偏振测量而设计和研制的,是近几年内即将打开的一扇新窗口。由于GPD的小质量,低功率和紧凑的几何形状,我们提出了一个立方体卫星任务偏振光(PolarLight)来演示和测试该技术直接在太空中。没有光学器件,只有一个准直器将视场限制在2.3度。充满0.8大气压的纯二甲醚(DME),并由100微米厚的铍窗密封,灵敏面积约为1.4 mm × 1.4 mm,PolarLight允许我们观察天空中最亮的X射线源,计数率为,例如,~0.2计数/秒来自蟹状星云。PolarLight大小为1U,安装在6 U CubeSat上,于2018年10月29日发射到低地球太阳同步轨道,目前正在测试中。计划在2019年推出更多改进设计的产品。这些测试将有助于提高未来任务的技术准备程度,如增强型X射线定时和偏振测量(eXTP),更好地了解轨道背景,并可能有助于通过观测最亮物体来限制物理学。
