摘要:

POLAR是一种新的星载探测器,旨在测量50-500 keV能量范围内前所未有数量的伽马射线暴的偏振。该仪器于2016年9月15日在中国天宫二号空间实验室上发射,旨在通过测量入射光子的方位角散射角分布来测量硬X射线通量的偏振。为此,需要详细了解旋光仪,特别是由仪器的非均匀性引起的系统效应。为了研究仪器对偏振的响应,POLAR在法国的欧洲同步辐射设施进行了光束测试。本文将介绍束流试验和仪器性能。随后概述了为该仪器开发的蒙特卡罗模拟工具。最后,将提供测量和模拟仪器性能的比较,并给出仪器对偏振的响应。

英文摘要:

POLAR is a new satellite-born detector aiming to measure the polarization of an unprecedented number of Gamma-Ray Bursts in the 50-500 keV energy range. The instrument, launched on-board the Tiangong-2 Chinese Space lab on the 15th of September 2016, is designed to measure the polarization of the hard X-ray flux by measuring the distribution of the azimuthal scattering angles of the incoming photons. A detailed understanding of the polarimeter and specifically of the systematic effects induced by the instrument's non-uniformity are required for this purpose. In order to study the instrument's response to polarization, POLAR underwent a beam test at the European Synchrotron Radiation Facility in France. In this paper both the beam test and the instrument performance will be described. This is followed by an overview of the Monte Carlo simulation tools developed for the instrument. Finally a comparison of the measured and simulated instrument performance will be provided and the instrument response to polarization will be presented.
